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.

I ran my 3.6s off of a stereo Belles 150A and generally liked everything but the lack of bottom. I am not sure if the lack of bottom was purely due to the 3.6s being power hungry, or just how the Belles 150A is voiced. If you have an opportunity to listen before buying I would strongly recommend it. The 350A may be a better choice because it looks like the entire architecture was designed around being a "muscle amp", and a very reasonably priced one at that.
