Which brand power conditioner fit for devialet

[David A]

I haven't seen a P3 in use. I borrowed my dealer's store demo P5 for trial before ordering the P12 and the P5 worked fine in my system but the P12 definitely sounded better when it arrived (the dealer let me continue to use the P5 while he waited for my P12 to arrive). My 140 sounds better with the P12 than directly plugged into the wall, and that was also the case with the P5. 

My 140 sounded good with the Isotek Aquarius as well, but it  definitely exhibeted more drive with the P5 than with the Aquarius, and a bit more drive again with the P12. mdconnely said that he found that power conditioners didn't work well with power amps. I tried several conditioners with the NAD M3 integrated that I was using prior to getting my 140 and I had similar experiences but I did find that newer conditioners did tend to work better with amps than earlier models, I think manufacturers have improved their products over time. I think good conditioners these days can deliver good results with at least some amps but I think a lot depends on how much current the amp draws. My 140 worked better with the Aquarius I had been using with the NAD and I think in general Devialet's present an easier load for a conditioner than a class A or class AB amp of the same power.

Even so, I think you should try any conditioner you're considering using with an amp before you buy. Amps place the biggest demands on a conditioner and some amps place heavy demands on a conditioner.
