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.

For everyone's reference, Lumin is at:

I did not find US prices on the site, but according to Mike Bovaird's review on Audioshark.org, the Lumin digital streaming player price in the USA is $7200.

We've had this discussion with him in another thread, explaining that I'm getting great audio quality over USB, and to him this is all a fig newton of my imagination. He doesn't care if aliens from 5000 years into the future show up with some nanoo-nanoo technology that makes USB sound like angels caroling in your ears - he'll tell the aliens the same thing, "you aliens need to use SPDIF". The fact that, just for example, the Oppo BDP-105 (which I don't own, but may buy for a 2nd system) is getting rave upon rave reviews, including for its sound quality over USB (it has XMOS chip + asynch USB), has no bearing in Cerrot's thinking. To him, all those reviews are a USB conspiracy, not unlike the Loch Ness conspiracy. The ONLY thing USB should be used for, other than computer mice, is to put some marinara sauce on top and to be enjoyed with a nice Chianti.

You get a gold star for using creative writing to rant....

BTW, while back in MN for a wedding, I heard a top dollar system fronted by Magico S5s that had as its digital source an Exemplar Audio modded Oppo 105. I brought a USB flash drive of music to use as test tracks, plugged it in, and it gave the Brinkmann turntable a run for its money. So yes, its a matter of IMPLEMENTATION.

That aside, my system is without a dedicated digital transport at present, and I succumbed to using an unmodded Mini with a Belkin USB cable, and it sounded liked rat piss. I understand why the naysayers nay....

Get a sound card. ESI juli@ for $149. Spdif out. All you need, plus a coax cable into your dac.

That is an option, and one that the Alpha Berkley crowd runs with....

"Is computer Audio a Bust?"

Is this a serious question?? If so, the one asking is grossly uninformed and/or naive.

No, just a rhetorical question to stimulate discussion. As you can see, some people do actually feel that way, and its still a valid opinion...

I should add that the PC or Mac/DAC combo introduces variables that can result in inferior SQ. The Lumin eliminates these variable by combining the computer and the DAC in one housing, with the power supply in another, thereby eliminating the USB or other interface and clocking problems. The designer has total control of the results.

Indeed. I actually looked at one. It does however take away some of your own control over SQ. I would rather have a dedicated digital transport and a DAC of my choosing....
