I have the cm8s and I would agree that you need to be careful when matching the speakers to an amp.
Thr treble I n the cm8s can become a litle dominant at higher volumes when used with a bright amp, however it really is personal opinion. I use them with an amp that's just on thr warm side of neutral and it balances out quite nicely, however ive also heard them with the Roksan Kandy (which is not in itself bright), but the treble sounded quite hard. With that said, I knwo of a few people who use them woth bright amps and they really enjoy the sound.
I not familiar with your amp, but if it is very detailed then you might want to listen to the combination over a long period of time (preferably home demo) before you buy. Itvmight be exactly what you need, but it may also be death by detail and become fatiguing over time.
Enjoy.
