PC-Audio vs. High-end CD Player-GAME OVER


Hi All,
I just auditioned the Wavelength Audio Cosecant DAC on a very nice system at the local dealer. It was run through a Hovland 200 preamp , a Plinius amp and Avalon Eidolon Diamond speakers. This is all in a very well treated, good-sounding room.
It was, in a word spectacular. Beautiful tone, excellent bass, imaging soundstaging, etc. What was really amazing was a sense of space, or ambience that was imparted. We then compared the same CD's (Diana Krall, Jennifer warnes, some jazz), on a Levinson CDP. I'm not saying that the levinson is the last word in players, but it was what he had on the shelf.While it sounded good, it was much more bright, and "constricted".
Control was through an Imac using I-tunes, and the CD's had been nurned using Apple Lossless.
I ordered my Crimson on the spot.

Goatwuss, Empirical's solution is a good alternative, but there is still another one: Logitech/SlimDevices Transporter. It is wireless and has a wordclock input, so that you can connect it to a top-quality DAC like LessLoss with wordclock output and you'd be up there with the big boys. I have been using a Bolder-modded wireless SqueezeBox2 for more than a year and recently added a Monarchy Audio M24 preamp/DAC; the sound I'm getting is extremely good.
The drives, memory, processors and interfaces in the PC-Audio are powered with the noisy switching power. You can isolate this from the DAC but that does not help anything when it comes to the actual data processing.

Isolating the DAC from the PC brings an obvious improvement. Why? Try supplying your DAC from the switching power supply in the computer and see what happens with the sound.

It is very interesting to me that no one acknowledges the fact that PC-Audio remains powered by the noisy switching supply. But it does not end here. How about the fact that your audio data is being transformed to many different protocols inside the computer so it can be processed and stored? Do you really believe this can be a better solution compared to a quiet linear powered and precision clocked dedicated audio DSP directly hooked up to the DAC with 5 inches long cables? Not in my book!

Again, convenience and nice sound is a suitable description for PC-Audio. But when it comes to the best possible audio quality, I will have to disagree.

Finally, I have 5 desktops and 2 laptops here. :-)

Alex,

Have you experimented with the Slim Devices Transporter. This device seems to take out all of the factors of which you complain about PC audio. Linn has even jumped on board with their $20,000 Klimax DS. Both are network servers. So, if you stream wave files over the ethernet cable, no processing. The Transporter with a great DAC should equal or best most stuff on the market. Maybe not your players, who knows, but have you tried a network streaming device. You are right about PC audio. This is probably a dead end, as well as USB DACs, but network streaming seems to combine the best of both worlds. If you added an ethernet port to the NWO, that would be exciting for me.

I have a rubidium clock hooked up to my transporter right now and it sounds pretty good, but the dac is certainly inferior. I would love to hook up my transporter and clock to an Alps DAC. Is it out yet?

Thanks,
andy
The SD Transporter and SB3 are effected by the PC noise. The ethernet port is connected to the PC's noisy switching power supply.

Both the Transporter and SB3 also use SMPS units to power internal circuits.
Alex,

I am trying to understand what you have written about the noisy switching power supply of a computer. I can't see how the digital information would be modified by a switching power supply.

Once it leaves the computer via an optical USB cable, the DAC would have its own linear power supply to process the information.

By the way, I also suspect that you build and design great CD/SACD players.

Thank You
