Belles 150A Reference in Mono???

I have a 150a ref.'Been driving my Sophia-2's for near a year. I just bought the 350a ref. I didn't read what you read on running them in pairs ;but it may well be true. In a few threads I tried to get some info on the 150 ref vs 350 ref but got zip so I just up and bought one.----HUGE--- diff. You can take my word for it/ or not. This single 350 works real nice with my Soph. 2's. I think the 150 ref is good for what it costs. If you ever change you will see the 350 ref is a REAL amp.
I'm not sure why but 6moons and soundstage don't exude much confidence---for me. AND--we don't get much chat from owners;here.
Be BOLD--look for a 350a ref./used.

I was thinking that two 150a run in mono (500 watts) would reproduce more low end instead of the belles 350 (250 watt)or my current parasound hca-2200 (250 watt). And it might be less expensive as well.

Troy,dude----It ain't the watts it's the quality of the watts.---One listen is all it should take.
