power amp for Dynaudio Contour 3.3

I look for the best suitable power amp and pre amp for my system - Dynaudio Contour 3.3 (speakers) and Micromega Solo (CD player). Jazz is the preferable style. The room is 30 m2.
The Dyns love power to sound their best. I have Pass Labs X600 monoblocks and an Audio Research Ref. II (tubes) preamp. They are an awesome match with the Contours 3.3's. A few years ago, I had the Plinius SA250 Mk. IV which is less detailed than the Pass Labs, but also a good amp for the Dyns.
i am driving mine with a 30 year old MAC 2205 and am very satisfied. awesome vocals and quick solid base without overpowering the music. with adequate power, its hard to go wrong with these speakers
I run mine with Bryston 7Bst mono blocs and Bryston BP-26 preamp and I couldn't be happier.
