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.

On the bass response of each, as a stereo amp; Truly it isn't even close.---Then guess what?-- the rest of the spectrum is ALSO that much better. The 350a Ref is much quieter. I was never aware my 150Ref was noisy;when you compare the 2 it is one of the first things you notice. The treble brought out the Sophia's(2's) potential. This amp just does everything on a finer scale. The bass becomes the cornerstone of the music,clean and powerful.I seriously doubt 2 150's would have bass as clean and powerful.---Sure 2 150's may well have more bass than a single 150---BUT, amplifying X's2 doesn't improve the quality; only the quantity.----Oh yes, the improvement in the midrange matches the treble and the bass.Soundstage and depth of image---on the same improved level which is easily twice that of the 150. Everything is better, this is the whole package at a giant-killer price---used of course. Remember guys, this ain't a 6moons guy. This is from a guy whom ran the 150aRef for a year and then aquired a 350aRef.BTW, I also ran this 150 on Merlin MM's and sold them 'cause I didn't have enough bass---Well now I understand and it's called live and learn.
