Is computer audio a bust?


In recent months, I have had several audio acquaintances return to CDPs claiming improved SQ versus their highly optimized computer transports (SS drives, external power supplies, etc, etc).

I wanted to poll people on their experiences with computer "transports." What variables have had the most impact on sonics? If you bailed on computers, why?

I personally have always believed that the transport, whether its a plastic disc spinner or computer, is as or more important than the dac itself and thus considerable thought and energy is required.

Fidelizer opened my eyes with respect to computer audio. JRiver alone didn't do a whole lot for me in terms of sound quality. Running fidelizer made all the difference in the world and encouraged me to go down the computer audio rabbit hole. Now I'm running Audirvana on a mac mini while my cd player is literally sitting by its lonesome in the spare bedroom. Audirvana will soon have it's own file management and will no longer be tethered to itunes. Can't wait.
ANyone who has an Amazon Fire TV device already, or thinking of getting one, I am getting very good results from that running Plex ($5 app for Fire TV) to stream same .FLAC files as my current Squeezebox system that I have run happily for several years now.

Amazon Fire TV ($99) is a fairly decent powered, Android computer specialized for streaming high res audio and video. It has toslink out that can run into most any DAC. PLEX connects to PLEX server you run on your computer file server.

An added benefit of PLEX is that you can access your media (video, photos, music) from anywhere with an internet connection. I use an Ipod with good quality earbuds at the local pool for example and sound quality is top notch.

Its all very good stuff. Not a bust by any stretch.

You would be mistaken. All of my interfaces are custom designed by me.

I have modded many CD transports in past years. Some of these became references. None of them hold a candle to my computer audio interfaces. It helps to have 30 years of digital design experience in the computer industry.

"According to Steve Nugent, wireless/ethernet is supposedly a superior interface in terns of jitter"

True, but still only as good as the designer designing it.

"Does having a asynchronous USB help with jitter and obviate the need for reclocking or SPDIF converters, as claimed here?"

It does eliminate some sources of jitter, namely the computer clock, however jitter can still be introduced by common-mode noise and RFI. The master clock and the associated clocking circuitry in the interface is also critical to getting a good result. The design will determine whether Async USB interface is good or not. There are a lot of mediocre ones out there.
