CES 2010 dCS debussy

Recommended Posts

From CES: introducing their new Debussy digital-to-analog converter. Housed in the sleek U-Clock chassis, Debussy features a wide array of inputs, including dCS' patent-pending asynchronous USB, as well as traditional S/PDIF and AEB/EBU. An LED-based display indicates active input, sample rate, and volume level. The control board and Ring DAC are derived from those in the Paganini DAC, with variable output of either 2V or 6V available on either XLR balanced or RCA unbalanced analog connectors.


Chris, did you have chance to see this piece?

dCS's Async USB implementation requires only the OS built in drivers (a.k.a. Driverless implementation) just like Ayre and Wavelength.






...in my opinion / experience...

While I agree "Everything may matter" working out what actually affects the sound is a trickier thing.

And I agree "Trust your ears" but equally don't allow them to fool you - trust them with a bit of skepticism.

keep your mind open... But mind your brain doesn't fall out.

you don’t need to mess with MIDI Settings on the Mac as it switches resolution and bit depth automatically (i.e. no need for Amarra)


(At least that’s true for the U-Clock, and I guess they have no reason to change it)

I did a couple of quick searches and came up with very little, so I thought I would give this thread a bump.


I haven't found much to read in the way of reviews (in English) or forum buzz regarding this dCS Debussy (USB) DAC.


Are there any people here at CA using them?

I also have one and think it is very good too.

Thanks for the reply Chris. Someone beat me to it, but I was wondering the same thing - how does it sound and in comparison to its peers.


In a few quick searches, I haven't seen it discussed or on the C.A.S.H. list. Did you actually purchase one? or is it in on review loaner?

There's a review of the Debussy on the Stereophile website: http://stereophile.com/content/dcs-debussy-da-processor


Technically, it looks superb. And interestingly, jitter measurements for its spdif/aes inputs are pretty much identical to its async USB input. Async USB/firewire inputs are all the rage nowadays, but it seems 'legacy' inputs, when done right, can still hold their own.

>>We had one here,not bad, a bit digitally sounding I thought?


But of course, you'd say that, wouldn't you? Why comment when it is impossible for you to make an objective one?

We just brought one in for an event we were having as a loaner to drive D'Agostino Momentum Mono's and Wilson Sasha's. Many commented that this was the best they had ever heard Sasha's sound and days later we decided to become a dCS dealer. SInce then we've been enjoying it immensely. Whoever said that the sound it produces is "digital" I would have to respectfully disagree with. The sound we achieved was anything but. The best way to describe the Debussy is that it just sounds correct. I'm not much of a "reviewer" so I'll leave that up to the pro's but I can say that everyone in my store, both employees and customers, have been very impressed. I can't wait till we get the U-Clock!


P.S. Chris: Thanks for continuing to do a great job with this forum. I've learned more about digital audio from posts on here than from the rest of the industry put together.
