Air Tight ATM-2 vs CAT JL2 with Avalon speakers


Have any of you compared ATM2 with JL2? Which of them will fit better (in term of sound quality) with the latest Ascendant 2 (or other Avalon speakers) in rather small room 10x18x10 (know about CAT's heat :-) ?
My priorities are: deep & stable soundstage, full, colourful sound with realistic midrange.
Is ATM-2 enough for Avalons?

Best wishes!

I used to call "sweet" amps like Accuphase A30 (e.g. with Audio Physics, Thiels) but with Ascendants it sounds lean with boomy bass. Quite unexpected.
Don't know Ayre, nor Spectral gear which are famous for synergy with Avalons cause they're not available in Poland, but a few really expierenced people reported me of best results with strong PP tube amps.
the a30 won't make it...something like the p450 would. the little class a amps will be overwelmed. even the huge a50 will sound thin.
I've finished my research with Jadis DA88s. Absolutely amazing amp, probably the best integrated ever made. Synergy with Avalons is unbelievable. Rest of system is MBL 1531 and Stereovox cables. Together it gives me the very best sound in my life. It's so listenable and universal for EVERY type of music.

Holy Grail:)
