My first "real" hifi rig was a Carver CM-1090 integrated amp; I kinda wish I still had it, for sentimental sake and for use in my bedroom rig. I remember it as sounding pretty good, but that could be rose colored glasses.
I actually do still have a couple of the last Carver amps, the a400x's. I briefly had one of 'em hooked up to my Hsu subs to compare to the 500 W Hsu amp. I felt the Carver was ballsier and more powerful with a cleaner more muscular sound; however, the versatility of the Hsu amp won out (has a volume knob, eq'd specifically for the Hsu subs, has X-over and infrasonic filter, etc).
As a kid I lusted after an M 1.0t for years...never did manage to get one. I worked several summers but always blew too much to buy one!
To this day, I still look at them on ebay and tell myself my present gear is much better. Still I want one!
BTW, Mike, what do you use that C-4000 for? Is it hooked up? Man I wanted one of those SO bad, too, back in the day...
