Mcintosh mc275 or rogue m150/180

The M180 are very nice, but never really impressed me (have auditioned in a few systems, but not owned) like my Apollos. I'd wait to pounce on a used Zeus (which occasionally come up used for very reasonable prices) and re-tube it in KT120s. Then pair with an Athena pre and you'll never again want for more power or quality.

These Rogue amps also really like a good 5751 (e.g. GE black plates) in the phase inverter position, and 12BH7 in place of 12AU7.

I can tell you that the Russian KT120 is a very happy marriage with Rogue power amps. You'll get an appropriately long lifetime out of 'em (having run my last set 3 years), and they sound awesome. Also Rogue may have gotten that rep from the M120 days when their amps were cathode bias -- which runs hot as hell and is definitely hard on power tubes AND circuit boards/components. The M150 and more current models are much cooler and easier on the tubes.

And yeah, 200 lbs for a Zeus is tough to handle without a strong friend. Rogue said that's one of the big reasons for the Apollos. But hey -- it's also real hard for burglars to steal?
