capacitors for each DAC may not be what is claimed in literature: http://www.head-fi.org/forums/f7/valab-dac-first-impressions-378459/index5.html

So, if I go budget, I'm leaning toward the Vintage Audio Lab; if I splurge, I think that the Cambridge Audio may be the way to go.

If anyone here owns any of these products and would like to comment....

It's not enough to simply have a USB input on a DAC. Implementation is tricky and only a few manufacturers are doing a really good job of it. (I've ordered a Keces to check it out.) For example, with my Bel Canto DAC3, I prefer Toslink out of my Mac Mini to USB out to the Bel Canto's USB input. Bel Canto has just introduced an accessory box to convert USB to S/PDIF. They claim superior sonics as well as 24/96 capability. You are definitely not hearing the Bel Canto at its best when using the USB input. And they are not alone in this regard -- most manufacturers are not doing USB right.

I've thought about taking that route but wondered if having one more converter in the line would be a plus or a minus. Do you have an idea how much the Bel Canto accessory box will cost? A product like that would open a wider range of DAC options.

While I realize that getting the USB connection set is tricky, I wonder if the new crop of DACs have the wrinkles ironed out? The DacMagic is getting pretty good reviews.

Most of the USB DAC chips used are not up to the task at hand. There are only a handful of DACs that "properly" implement the use of USB, i.e. the Benchmark DAC-1 (which has other deterrents). You'll repeatedly see chips such as the PCM2702/4/7 and CS102-108 turning up in these products. Bel Canto is a fairly expensive DAC that is looking to better the USB connection, however I'd prefer it in one box not two. Not to say, as an above poster, that having everything in one box improves sound quality. If it's done right it can. A poorly designed or built integrated amp will suffer as ideally these units will have separation between them. Still less expensive when built properly?

The Bel Canto box is $500. Includes a short length of Stereovox digital cable. I don't believe they are gouging us at this price. Rather, it shows what it takes to do USB right.
