CD-Ripping Guide

Recommend to use the DVD-Burner made of MediaTek chip,
ASUS DVD-Burner is using MediaTek chip.
There is no clock inside the ASUS DVD-Burner,
If you have good SATA cable & good main board clock,
It will be better than any DVD-Burner with clock inside.

In the other hand,
To ensure the ripping quality,
You will need to use your best sever for the ripping.

DVD-Burner with solid aluminum suspend block

12V lead-acid battery to powered the DVD-Burner

12V & 5V battery adapter for the 12V lead-acid battery

Using 1M SATA cable connect to the server

Please use the Demagnetizing Magnetc Memagnetizer for CD before rip

Very nice music & recording

I am using foobar2000 to rip CD.

So I don't use Lan Isolator.

THE DIFFERENCE OF GRAY,BLUE,RED & JCAT CABLE

2013-09-15T02:34:00.002-07:00

Multi-core conductor has much higher bandwidth than single core conductor and bandwidth is a very important parameter in digital audio applications.

Corresponding to the sound performance,
multi-core conductor will have rich harmonics and detail and with low and high frequency extension.
Single-core conductor will have high denseness to the vocal (mid. and low-mid. range).

The TZ YUN Grey, Blue and Red cables use multi-core conductor so they have a similar sound style.
The main difference between the Grey, Blue and the Red cable is the silver content.
The Grey cable uses 10uM silver plating.
The Blue cable uses 15uM silver plating.
The Red cable uses 20uM silver plating.
Multi-core conductor with 20uM silver plating is expensive,
even more expensive than the single-core pure silver conductor.
My experience is that the multi-core conductor will be the best choice for a digital cable.
That is why I only use multi-core conductor for my digital cables.
Grey, Blue, Red and the JCAT cables have the same basic performance and they are well balanced across the entire frequency range.
Although the JCAT cable is the same grade as the Red cable the JCAT cable is designed according to JPLAY's request.

The main difference between them is the JCAT cable is built using high density Z stranded as the central core with the outside of the inner cable has used mid density S stranded. Please refer to the picture.
This mean that the JCAT cable will combine the strong points from both the single-core and multi-core conductor designs.
This conductor is more expensive than the Red cable,
so the JCAT cable price is slightly higher than the Red cable.

I recommend you to use the JCAT cables with the Jplay Ultrastream mode.
That will be a perfect match!!

The Grey cable has a very high value cost to performance ratio.
In the majority of CATs the Blue cable is a great choice.

The Red cable is designed for a high-end grade CAT.
The Red cable is absolutely the highest performance cable,
it needs an high-end grade CAT to appreciate the full performance.

Power supply for the CAT

2013-05-08T15:06:00.002-07:00

Although it seems everything matter with PC audio(CAT,CACP,PcHiFi...)

But as time goes by ,

We have found out that are only three key points to the hardware.

Power supply,clock & vibration.

All other things are connecting to them.

Same as analog audio devices,
The power supply is the elements of the most basic.
With a good linear PSU,
It will solve many problems with hardware.

Because a full linear PSU for CAT is big & expensive,
A dc to atx psu will be the appropriate choice.

This dc to atx is similar to picoPSU,
But it accept +16V to +24V dc input.
picoPSU accept only with +12 dc input
So picoPSU's +12V output is not a fair supply for MB & CPU
And I choose this wide range input psu for my server

A 120W linear PSU for picoPSU is very important,
If you use adapter for picoPSU,
The SQ will be worse to a good atxPSU.

A single picoPSU is not enough for a full dynamic,
It is nothing to do with the power input.
That is because of MB's power supply circuit structure
You need another 120w linearPSU for CPU
Two linearPSU will improve SQ & dynamic.

Power cable is improtant,
But I won't recommend silver power cable,
Only if you have used linearPSU for picoPSU.
Power supply is the basic of CAT,
All hardware connect to power supply.
Good power supply will improve every hardware,
EX. SATA cable,USB card,CPU,RAM................................................

Use a linear 12 V input for picoPSU will be fine,

But wide range PSU will have a better conversion efficiency.

For example,

A 120W picoPSU need a +12V/10A min. input,

A 120W wide range PSU could be use +24V/5A min. input

Linear PSU will have higher performance and lower cost & heat with low current output.

That is why I choose wide range PSU

A good linear PSU for the picoPSU is very important.

Although DC to ATX PSU will generate EMI,

But a linear PSU or battery PSU will decrease EMI,

And MB have many switching PSU for CPU,RAM.......

You should use EMI shield for chip & cables of course.

That is why I use aluminum block to shield the chips.

And a separate linear PSU for CPU will improve the SQ,
Just insert the PSU with 4pin or 8pin ATX plug into CPU power socket will be fine

Battery PSU is a clean power soure,
OS SSD,USB card with a battery PSU will increase sound stage,high & low extention
Very low noise floor & smooth sonic.

But battery need a vibration control,
It sounds quite different with a wood block for vibration control
Vibration mus be noted to battery supply

This is a battery structure digram,
It has large area of the parallel structures
That is the reason why a battery afraid of vibration.

Unfortunately,
Cheap mobile battery PSU is design only for cell phone,
It will be no better than a linearPSU
So we have to build a audio grade battery PSU

But even so,
You could hear the improvement with a vibration control to this PSU

Why the SATA cable make sound different?

2013-04-01T11:31:00.002-07:00

The SATA BUS contains a transmit and receive 2set of balanced signal
Both contains CLOCK inside the bus
And SATA bus bandwidth up to 3GHz
So SATA cable need a very high performance conductor

Although the regular SATA cable can also be functioning of the PC
But that is because of OS's error correction function
With regular SATA cable
Your CAT will always do a lot of error corrections
So a regular SATA cable will degrade the SQ to your CAT

With my SATA cable
OS's working will became simple & continuous
So my SATA cable do a big improvement in SQ
This improvement do not need you to do a AB blind testing
Just replace my SATA cable
You will hear the big different right away

For general user
You don't need any instruments to prove that
Because my SATA cable make your OS working simple & continuous
So you will get a shorter booting time,
This should prove the performance of my SATA cable

And with the similar reason
Use my SATA cable
You will have a shorter cd ripping time
And got better SQ from cd ripping

The conductor of my cable
Have been fully tested with professional instruments

After a lot of R & D
All conductors of my cable now
Are multi-cores of silver-plated copper alloy
This is the best conductor for digital audio cable I have tried

With my SATA & USB cable
Your CAT will became a wonderful source
Over a year
I had over 500 users world wide now
And have many postive feedbacks from those users.
So use my cable with confidence

ODM of SATA & USB cable is welcome
Any question,please contact
ppastudio@yahoo.com.tw

-------------------------------------------------------------------------------
FYI,
Although these sata cables is not directional in manufacturing process,
But many users claim that my sata cable has a stronger performance for certain direction
For this reason,
All my sata cables have marks on it to identify,
You could try my sata cable's direction before burning the cable,
Higher energy,more smooth will be the right direction for the cable.
And these cables used silver-plated copper alloy,
You should burn these cables 200hrs at least,
And these cables will need 6 months for full performance.

Optimize the Musiland 01USD DDC

2013-01-25T13:24:00.002-08:00

Some friends of mine have heard the modified 01USD.
It sounds good in neutral & well balance.
So they asked me to do some more.

This project is planning to use 4pcs of 18650 Lithium battery-powered
And USB +5V charging the battery
Battery-powered is ideal and cheap to DDC
Because if you use a linear PSU for 01USD
For a better sound quality,
You need to use an expensive power cord.
And battery-powered has a very low noise floor & high resolution to full sonic range.

This is a new development silver wire output transformer for clock generator

Output waveform of low jitter TCXO with buffer

Output waveform of low jitter TCXO with buffer plus silver wire output transformer

As seen from the above waveform diagrams
The clock with better electrical characteristics after plus transformer
The results presented in acoustically
are better texture,more stable image & more 3-dimensional space
And SQ is naturally smooth, low distortion just like analog source!

Testing sample of second-generation resonance control small chassis

With two aluminum brick grip the main chassis
Very nice in the resonant characteristics and sound quality

My Solution with CD RIP

2013-01-15T13:12:00.000-08:00

This is my cat,
Base on a MINI ATX MB with ATOM330 cpu & nVdia ION chip for 1080P video playback
Fanless,Full linear PSU, Sealed full aluminum chassis.
All my ripping & playing with this CAT

I have changed Green Label SATA into TZ YUN III SATA recently
That is because Green Label is monitor style
It is near field listening,
Everything is clear and need a good optimization CAT for better result.
TZ YUN III is more smooth listening but in Green Label acoustics
Something like sitting in the 15th line of music hall to listen.
This CAT is for ripping & playing music
It is not a AV workstation,
So I like TZ YUN III more.
These TZ YUN III are prototype

End product of TZ YUN III SATA

I use CF card as OS & DATA disk

CF need very low power supply & better SQ to SSD

Two 18650 3.7V Lithium battery with auto charge for CF
It is more detail in full range,higher S/N ratio & more extension to high frquency than linear PSU.

This unit has 2 separate +5V output and up to supply 2 SSD in 4pcs 18650 battery.

I use 01USD as USB to SPDIF converter
This 01USD has been modified almost in everything,
Every chips has it's own power supply,replace low jitter Clock,
Superb grade silver pulse transformer for spdif output.
And in a sturdy full aluminum chassis.

01usd has a well balance response and less coloring tone
After modified,It has very good sound quality!

I use DVD burner,
Ripping data via eSATA to CF data disk inside the chassis

DVD burner's power is supply from my cat
My cat support 2 separate linear PSU for DVD burner & HDD

Restore ripping data to HDD in 3 layer anti-vibration platform outside the chassis

Mike Garson's The Oxnard Sessions for ripping demo

DVD burner in single platform

"Green Label" The Professional Audio Grade USB & SATA Cables

2012-04-06T14:36:00.001-07:00

A recording engineer
by profession, 

I specialize in live concert recordings. 

I found most commercial
USB and SATA cables that I use for my digital recording system to be lacking. 

Hence started my journey to build cables that would meet up to my stringent
requirements for sound quality with neutrality and balance figuring very highly
and using live concert sound as the benchmark. 

Some videos of my work.

For professional audio

All equipments must have highly quility in sound performance

Neutral and balanced are basicly requirements

And very clear sound's shape & contour 

The most important thing is those equipments must provide natural living and smooth sense as live concert

So I have developed Green Label USB & SATA for professional audio

In addition to my own use

Green Label USB and SATA is created with the above qualities in mind and is now widely used by other recording engineers here in Taiwan

As analog cables run
low frequency signals and digital cables run higher frequency data and clock
signals, 

analog tuning techniques such as gas fill in, oil fill in, cable ring
and SATT cannot be accurately implemented to digital.

The solution to
overcome this problem is to treat digital cable as a hardware of CAT.

SATA cables tend to be
more difficult to develop as they require a much wider bandwidth.

 To achieve
this the application of SATA Generator, SATA Analyzer and professional AP is
utilized.

 SATA performance also requires the measurement of clock jitter as
well as the transmitted and received signals.

All my cables have been designed with one goal in mind,
and that is to achieve as close as possible transmission of signals in very high end and much more expensive cables that are currently being used in professional PC based audio equipment eg hard disk recorder, a/v workstation, PC recording interface etc… but at a more affordable and realistic price.

Green label has discontinued.
TZ YUN III is Green label upgrade version and in the same price.
It is more fuller & smoth than Green Label.

BEST SATA CABLE FOR AUDIO IN THE WORLD

2012-04-01T09:28:00.003-07:00

In my research,
Sata cable became the weakness point to the modern pc base music source
It is because that has no audio grade sata cable in the market
All sata cable you have seen were costdown products
So I evolved sata cable for my music server half year ago
And that sata cable has great improvement of the sound

Here are feedbacks from users of my sata cable
---------------------------------------------------------------------------
Feedback from High End Speaker designer:
Dear Mr. Pang,
The cables arrived and I installed them on my PC.

I had in general 4 SATA cables (SSC, 2HDD, CD Drive) and removed all and installed yours on the SSC (with Win 7 OS on it) and the other on the one HDD with music.
I let my SATA filters from SotM in place for the first testing.

What to say? I was a huge improvement on the sound.
Much more naturallness in the tone colours and harmonics much more resultion and staging. Incredible.
The only drawback was that I first had the impression of less punch in the bass.
Today I listened again and the bass was o.k.;
may contact settlement or burn in of silver cables.

Overall the improvement is huge.

My system consists of a
- dedicated main power chord in the wall
- Fuructech wall outlet
- Fono Acustica Armonico PC
- Vertex AQ Hi-Res Taga distributor block (2 - one one the digital component; one on the analog)
- Vertex AQ Hi-ResJaya Shunt filters (5)
- PC (feed with Fono Acustica Armonico PC)
- silver SUB lead
- Human Audio Tabla USB/SPDIF converter
- Vertex AQ Aletheia DAC
- Vertex AQ Hi-Res interconnects and speaker cables
- Thrax Dionysus and Spartacus - preamp and poweramp
- Kaiser Kawero Speakers
- 7 Lessloss Blackbodies
- 6 Steinmusic harmonizers
- 32 Tchang sugarcubes
- dedicated room acoustics (more than 60000 Euro invest) with custom tuned absorbers and diffusors

-Analog:
-Kuzma Stabi 4 XL with 4 point tonearme and My Sonic Lab Emminent cartridge -Audio Research Reference 2 phono

I am so satisfied with your cables that I would love to exchange the other Sata cables in my PC as well.

Thank you very much

Feedback from co-auther of cplay:
I received the silver sata cables a few days ago and have allowed for some burn in time in the system.

What can I say, the improvement in SQ is definite!
I get lower a noise floor giving better definition to low level details.
This is like doing a power supply upgrade and more.
Do you understand why this is the case?
Perhaps the all important mobo chipset sees a superior ground connection?

Thank you very much for sharing - I think you should go mainstream and offer this product to the public.

Feedback form co-auther of jplay:
Hello Pang,
I picked up the package today,
thank you for your great service!
I've tried USB cables so far.
I have to tell you that I'm truly amazed by the performance!
Your USB cables, especially green one,
made the most dramatic improvement in my system I can remember!!!
My jaw is on the floor.
And believe me, I have few very expensive USB cables:
SotM 7N silver streamed, Acoustic Revive SP and 1500EUR VertexAQ HiRez Illimani.
And you know what?
They all sound like crap in comparison to your cables.
Even the yellow one is better than VertexAQ!( Who would have thought?
I'm very confused, it looks so modest, but the sound is thrilling.
The green one is the most detailed and yet most enjoyable USB cable I've heard.
Absolutely stunning.
I've had goosebumps all over my body today which hasn't happen for a longer while until today.
Now I have to ask you for your other products,
I just have to, because based on my today's experience,
you're a true genius when it comes to audio.
I bet your other products are on par,

Linear PSU / State of the Art

2012-03-24T11:37:00.000-07:00

現今電腦訊源的應用範圍越來越廣泛
為了能讓電腦訊源的聲音表現能夠與類比器材具有相同的音樂性
一臺設計良好的線性電源就成為了電腦訊源不可或缺的硬體器材

這台線性電源的機箱外部尺寸為(含面板,腳墊,不含開關)
310mm長x120mm寬x130mm高,淨重近8公斤

全機使用8mm-10mm厚的鋁合金來達成良好的電磁屏蔽及諧振控制
不使用風扇散熱,機器也沒有震動
同時由於機箱的結構相當堅固
所以數台的線性電源可以相互堆疊使用而不會減損音質的表現

這台線性電源使用150VA(150W)的電源變壓器
最大可提供120W或10A的直流輸出
例如+12V/10A,+19V/6A,+5V/10A單組直流電源輸出
或是+12V/5A plus +5V/5A合計10A的雙組直流電源輸出

Today's PC base source become more and more extensive range of applications
In order to allow the PC base compared to analog equipment with the same musical
A well-designed linear power has become the indispensable PC base's hardware equipment

This linear power supply chassis outer dimensions (including panels, floor mats, non-switch)
310mm deep x120mm wide x130mm high, net weight near 8 kg

The machine use 8mm-10mm aluminum alloy to achieve good electromagnetic shielding and shock control
No cooling fan and no shake to the chassis

At the same time a very solid chassis structure let the linear power of the number of units
Could be stacked on top of each other use
And will not detract from the performance of the sound

This linear power use 150VA (150W) of power transformer
Maximum available DC output of 120W or 10A
Such as the +12 V/10A, +19 V/6A, +5 V/10A single DC power supply output
Or +12 V/5A plus the +5 V/5A total 10A Dual DC power supply output

一個良好的穩壓電源必須在大,小電流輸出時都能工作的很穩定
為了讓穩壓電源在大電流輸出時仍能夠工作在很穩定的狀況下
所以必須要使用大容量的穩壓ic的輸出電容與負載端的退耦電容
大容量的電容能夠延長電容的壽命
也就是能讓這個線性電源能在長時間的使用下
不至於讓音質劣化
基本上大容量的電容不會讓聲音速度變慢
不正確的電路設計才是造成速度變慢的主因

A well-regulated power supply must be in large, small current output keep stable
To make the power supply in the high-current output is still able to work in very stable conditions
We need large output capacitor and the decoupling capacitors
Large-capacity capacitor could extend the life of the capacitor
That is, let the linear power under a long period of use
Will not let the sound quality deterioration
Basically large-capacity capacitor will not slow down the speed of sound
Incorrect circuit design is the main cause to slowdowns

使用大容量的電容而會有聲音速度變慢的情形的話
往往是送電迴路與供電迴路的問題所導致
這也是我的線性電源必須使用搭棚的原因
自行搭棚可以設定最佳的迴路狀態
因而在負載端大電流的狀下
仍能維持回授網路保持很低的相移
這樣就會有很低的失真

Wrong transmission circuit and power supply circuit
Will be slow down the speed of sound in the case of large-capacity capacitor,
This is why I used scaffolding
Self-scaffolding can set the best state of the circuit
Will able to maintain the feedback network stay in low phase shift
Even large current thus the load end
This will let PSU keep very low distortion

十幾年前我就開始用無熔絲開關來取代保險絲
用無熔絲開關的優點很多
最近連作蚊量級管機的也開始拾人牙慧
開始用無熔絲開關來取代保險絲

雖然我已經用了銀錫
但為了保持良好的接觸來杜絕焊錫的不良影響
所以我焊接大面積的接點時
除了用恆溫烙鐵還要用尖嘴鉗將焊點及線材夾緊
這樣會在製作時會多花好幾倍的時間
這也是我的機器都必須裝很久的原因

使用XLR作為直流輸出
所以只要搭配不同的直流接頭
就可讓所有的週邊使用

This PSU used XLR for DC output
So change different DC connectors
This PSU will fit all devices

有了好的電源迴路後
電源使用好的線材就變的重要了
因為雖然是號稱"電流"
但實際上能量在導體內是不流動的
而是經由電子與電洞的交換位置來達成能量的傳遞
好的線材有很低的電子干涉與繞射的現象
這樣才能有很好的音質
這台線性電源內部全部使用我自行開發的鐵氟龍鍍銀線材
這些自行開發的線材能讓在這台線性電源大電流輸出時
仍能保持穩壓電源保持中性均衡的聲音表現

同時為了確保這台線性電源的輸出性能
電源變壓器不再從市場購買
而是採用我自行繞製的變壓器

Have a good power supply circuit then you need good cord to maxium performance
Good wire will lower electronic interference and diffraction phenomena
So as to have good sound quality
This PSU used my self-developed Teflon silver plated wire for top sound quility
Meanwhile, in order to ensure that the output performance of the linear power
Power transformers are no longer buy from the market
Instead of using my self-winding transformer to control quility

經由實測可以證實
機械震動會放大電子零件的電氣諧震
進而造成聲音的劣化
因而好的電源也還需要一個穩固的機殼

一台好的機器其實就是一連好的細節處理
有了好的平台
零件與電路對聲音的影響性就會降低
現在的HighEnd廠靠的就是如何優化的know how
沒有靠零件或電路就可揚名立萬的品牌

It has been confirmed through the measured
Mechanical vibration will gain electronic components's electrical harmonic shock
Thus resulting in the deterioration of the sound
Good power also need a solid chassis

One great PSU is actually a series of good details of the deal
With a good platform will reduce parts and circuit effect to the sound
The HighEnd audio depends on the know how in optimize to hardware & software
Not rely on parts or circuit
