Devialet Expert Long Term Experience?

NuForce SC-700 all copper speaker cable were an inexpensive well made sleeper that were a noticeable improvement over the Cardas Golden Reference with all the switching amplifiers I've used. 

I'm sure they're out of production by now. A thick rectangular copper ribbon wrapped in copper strands. I never found a switching amp that liked silver anything.   

Try the Darwin Truth II PC cables with the Dev 200 and you will be amazed with what pure cryoed silver with air dielectric can do. Bass definition like you've never heard before. The wires are thick and what I think is as silver is 7% faster than copper the combination of a huge bandwidth and fast response provides for a PRAT in heaven !! 

So I auditioned the Devialet Expert Pro 220 in my home over the weekend. I listened to it against my current system, which consists of an Audio Research tube power and preamp, PS Audio DAC, and Whest phono stage.  (you can see the details in my virtual system page here on Audiogon).

The Devialet is an impressive piece.  My system is no slouch however and I was not compelled to sell everything with a jumping up and down enthusiasm.  The fact that the little Devialet could run with the more traditional system, and sound on par with it, is a great feat and kudos to the people in France that designed and built this excellent machine!

I may end up getting one, but as I said, it was not the mind blowing experience that would be required to make the decision instantly.  The temporary lack of fully Roon Ready meant that I had some connection issues.  I was able to fix them, but they came back, and I had to fix again.  I am no stranger to this, but still, it is annoying.

The phono stage sounded great.  It was interesting to hear my vinyl played through a digital device and still sounds like vinyl.  I like the idea of possibly ripping my vinyl, if I take the time and care to do it properly.  Though I am still not convinced that I should sell my record collection and turntable.  We shall see how minimal I need to go with my system.

So my overall observation was good.  I just need more time to let this sink in!

I've been using Devialet for a while now (Expert 400 & Expert 200), coming off of Pass, Krell, Mark Levinson, ARC, BAT & McIntosh and have found it to be easy-to-use, very reliable and "sonically competitive" with Preamp. / Amp. / DAC combos priced well-beyond Devialet; that on its own is a big accomplishment, plus the additional benefits of form factor, aesthetics, energy efficiency (consumes just 30 > 50 watts) and Bass quantity & quality that is "the best" that I have heard, regardless of price. 

There are some problems with my d400s. It is that on some days the configurator remains silent and I have then sound coming from one channel. The dealer and folks at devialet have tried different firmware and cables but the problem persists. It is not a daily occurrence but happens at the most inconvenient time. For example, I and some friends sat down to watch the Superbowl on my big screen and got sound from one of sopra 3s. Very embarrassing, but on days like today the sound was just fabulous.
