also using AQ power cords which had another great effect.

I used to use AQ power cords as well and the result was satisfactory. Noting that Devialet is a very transparent and neutral amp with a slight warmish tone already, I used a pair of Gotham 87215 with a pair of Rhodium plugs, the result is astonishing! it brings out the most detailed treble with a high end sounding tone, the best I have ever heard from the Devialet. Of course, YMMV, but it is worth trying considering how cheap the Gotham is, the only investment is the Rhodium plugs, Furutech ones are quite expensive, but one can also sell them easily on second hand markets.
