John,

 

In your opinion, how does the Devialet's pre-amp/DAC section stack up against the Classe CP-800?  I ask this because they both appear to be cut from the same cloth so to speak; beautifully styled, apparent 18 bit resolution, switching amp/power supply, highly configurable, and relatively future proof.  And, when you start to add power amps to the CP-800, you get up around Devialet money anyway.

 

Regards,

Brad

"the most extraordinary product I have reviewed for Stereophile."

Considering the very long list of other very extraordinary products you`ve had your hands on, this says alot!

but in the end went with a slightly more conventional setup.

for exactly the same price as a D-Premier, I went with a Linn Akurate DSM and Mcintosh MC452 amp. I couldn't compare them back to back but I like the below features from the Linn:

4 HDMI input instead of 1 (yes I could have used an outboard HDMI switcher).

Ethernet input and DLNA server compatible (AIR feature was not yet released)

And the Mcintosh had way more headroom than the D Premier's amp.

My speakers are B&W 802 Diamond.

After some very good 1st impressions on sound quality driving "conventional" speakers (impedance curve not bellow 2-3 Ohm) I was curious to audition the D-Premier with my Martin Logan Summit X speakers. Sound quality is very good, until I pumped up the volume. At about 85db, the protection LED on the front panel starts blinking and the amp starts to mute.

I have reported this problem to Devialet and they say it should not happen, but my dealer had the same experience with other D-Premier units driving other Martin Logan models (Montis, Spire, CLX).

My guess is that this amp technology is simply not designed to drive impedance loads like the ones present in Martin Logan speakers, which drop bellow 1 Ohm in the high frequencies.

Looking forward to your comments.

That's what I expect, too.

Notice that with the new SAM technology, two Martin Logan speakers have been matched to the Devialet--the Theos and the Electromotion. Now, I am wondering about Maggies. If Devialet can both drive and tame those big bass panels, then that would be even more amazing.

Hey John.

Thanks for this great review. How do you feel the Devialet (and its new iteration) would stack up to a Pass X250.5/Classe Cp-800 combo?

Cheers,

Jon

I haven't heard the XA20.5 but the Pass XA60.5s have been my go-to amplifiers for the past year. The beauty of the Devialet is that it is just one box, with a digital section up there with the Classe. A review of one of the less-expensive Devialets is in progress.
