it likes to throw you a curve ball. Last week I received my new M60 V4's replacing m3 V2 I bought a few years back, the bowl of cherries. When I hooked them up my power amp craped out on me, no left channel. Thus the curve ball. My power amp is an ADCOM 545 I have had for about 20 years so I see no reason to have it repaired. But neither am I in a position to replace it after buying the speakers, Christmas almost here and a couple kids in college. Anyways I ended up buying a Parasound 2125 V2. I would have liked to have ordered the Halo A23 or maybe the Axiom amp, but I just could not justify it with all the other expenses I have. I should have it Tues. and will finally get to listen to the new speakers.
