Is there any good digital designer?
it seems digital design is harder than analog design.

good Q&A Charles Hansen, Gordon Rankin:
http://www.audiostream.com/content/draft#Jwd0w77ZLMYORVJa.97
http://www.audiostream.com/content/theres-no-such-thing-digital-conversation-charles-hansen-gordon-rankin-and-steve-silberman-p#HKAQvHqIkeqmVDhM.97

Charlie Hansen: "All of this can be boiled down to a simple phrase. “All of the problems with digital are analog problems.”

This is the primary reason that digital audio has taken so many decades to come close to the sound of analog.

The thing to remember is that digital systems are not immune to degradation due to noise. They tend to be much more highly resistant to noise than analog systems, but noise in any system will cause performance degradations."


Gordon Rankin: "But since digital audio is a streaming system, the timing of the bits is critical. If the bit changes to the correct state but at the wrong time, this is equivalent to changing to the wrong level at the correct time.

Another area to tackle is what is referred to as signal integrity. The signal leaves a transistor or IC chip and it has to make its way across the PC board, component-by-component so that the signal is degraded as little as possible. When you are talking about what makes one transport a “good sounding” one, again we are talking about treating so-called “digital” products as very high speed analog circuits. The clock frequencies in these units are typically between 10 and 100 MHz. When considering a square wave, a convenient rule of thumb is that the bandwidth must extend in both direction (higher and lower frequencies) by a factor of at least 10x to preserve the waveform fidelity.
So designing a high performance digital circuit means that you are essentially designing high performance analog circuits that have a bandwidth extending up to at least 100 MHz, and in some cases all the way to 1 GHz. The traditional rules of PCB layout connectors, signal routing, ground planes, solder joints, PCB materials, and even PCB coatings break down at these high frequencies."

More moronic blah blah?
It seems that brainlessness knows no limits. Both Mr. Hansen and Mr. Rankin speak nonsense. Wasting time on text like this is like reading the brochures from extreme audio equipment. All the things that "audiophiles" expect someone to say, get said with absolutely no indication that they understand what they are talking about.

I 100% agree there is no useful information in the text but this Q&A is telling me  "digital design is not easy".

both Gordon and Charles are good designers in comparison by others. gordon rankin was the first man who converted PC to a good transport.

I know this forum is not a place to writing and expanding moronic ideas but i should say non of audiophiles in this forum do not know "whats the secret of transport design?".
which of you knows why CEC TL0-X sounds completely different to other transports?

Looking for a good external Power Supply
I am looking for a good external power supply for ATX motherboard and Sotm pci to usb card.
i need 12v, 3.3v , 5v, -12v , 9v


sometimes i think if i use CEC TL0-X power supply it may help but i did not measured it's output voltage.
CEC TL0-X has 4 transformer with 7-pin dc output.

some battery power supply are in the market like acoustic revive and red wine audio but i think battery is a little dead at lower frequency harmonics.
very few companies sell external power supply in the market.

is there any idea?

Simple and cheap
hi Amir
Ive been experimenting for long with this till i discovered it can be so easy and cheap. 
Just get a isolation transformator and an HF blocker. In this order respectively, for the pc only. Available for small money from industrial purpose, 2nd hand. 
Got plenty of DC and scam in my industry city as well as routers and chinese switching supplies at home. Running the worst and the most sensitive devices isolated like above, its 100% clean (in relevant dimensions). 
CheersJosh

Purepower 3000 is on the way

Armen my friend in iran is importing PurePower 3000. i will use PP3000 and i guess it will sound good.
about isolation i should test some stuff but now my problem is finding a good PSU for my PC .

Isolation is everything
There is no problem if you isolate it. Theyre all crap so take any, isolate the AC, go out via Toslink or Usb transformator to cut it off galvanic.

PC Audio
I spend my time/effort/money to get a good sound from computer or MacBook.my trial and error proved me that I could not attack CEC TL0-X by Computer Audio.I also lost my money 4500$ in ordering external PSU to Paul Hynes. Paul is not trusted and do not pay him if you need external psu.
check computer audio forums like "computeraudiophile" and you will find every day news to get better sound but I think it is hype.the money you pay for PC Audio (motherboard/external clock/pcie to usb cards/cables/external psu/shield/chassis/ram/cpu/ground/network/software/dual setup/optimise codes/usb purifier/network streamer) maybe even more than a good transport.
after those trial and errors you will find CEC TL0-X sounds better than PC Audio at lower price :-))
I also paid for CAD GC3 Ground Control. GC3 is designed by Computer audio design from UK. GC3 claims to remove noise of ground line but in my system Audio Note/2way Living Voice the GC3 was not good in my system. it kills micro dynamics and I do not know why it's sound is bad.

I think Computer Audio will bother you if you think you can beat CEC TL0-X. 
my orders:macbook pro 1500$USB Cable 2000$Roon software 500$audirvana 140$Paul PSU 4500$GC3 Ground 3200$motherboard cpu ram 1500$berkeley alpha usb 2000$chassis 300$external psu 1500$optimise code and play 200$shipments 1000$

Toslink might help
Amir,
You can try to connect Toslink cable to your MacBook headphone jack, if your model supports this. In my case, it made a huge difference vs the USB interface. And then you can compare it to Toslink output from your CEC. Unfortunately, different software players sound different.

Max I have paid for all types of pc audio like dual PC setup , Single PC setup, linux on alix boards, old macbook , new macbook , optical , usb ,high speed cpu , low power cpu , jplay, windows , mac ,roon , async adaptive , all you find in computer audio have been tested.You can get decent sound from computer even better than many transports but it is impossible to attack CEC TL0-X.If you would like to have best sound i recommend you Do not waste your money and go for CEC TL0-X.CEC TL0-X is also very different to other transports and you get so much low level dynamics information from it .Don’t forget your system should be very transparent and linear bass response to compare CEC to your pc audio.
If your system is not so transparent then you could not get full potential of CEC.We could not stop computer audio and CDs will be replaced By files but i will not pay more on pc audio.

AES67
Hi.

Anyone in here have experience with AES67 (aka RAVENNA) interfaces? This kind of networked interface are getting a lot of traction on the pro-market.

I am particulary interested on the Merging HAPI.


Thanks!

Can you burn CD from Spotify?
Thanks for sharing this tips on playing audio files on CD. However, as I know, most audio files are protected by DRM. In this case, you can't save Spotify songs to your local computer let alone converting them to CD. But please just take it easy, as long as you get the DRmare Spotify Converter, you should have no problem burn cd from spotify. Just take a look at this tips and I am sure it should helps you out.
