Amps suggestions for ATC scm 40 mk2


Hello all, 

Firstly, I know some of you will say that if it is atc go with active, but ı went for passives because of money. Anyway, I have hegel h160, 150 watts into 8 ohm loads, it is generally good, but in some tracks which has especially high dynamic range ones, i feel it lacks some power to drive 85 db speakers. I know atc loves lots of  power, so i m waiting for your suggestions. my budget is about 3k$. By the way I can use hegel h160 as a preamp, with a new power amplifier or a new integrated. Thanks.

My ATC's (40's but the rare HTS style) sound fabulous driven by a pair of the Red Dragon Audio M100 mk. II Monoblocks. Loads of clean power. The ATC's can really deliver with those!
Thanks for all suggestions and comments. I definitely like hegel sound signature, but h160 a bit underpowered for atc’s. if ı can find hegel h360 or h20 as a second hand, I can buy it. Also, I found primare a32 power amplifier and pre30 for 3k$, they are 250 watts into 8 ohms, anyone tried these?
