Mcintosh mc275 or rogue m150/180

my janszen speakers arrived today and by what I am hearing this all may be a moot point. holy smokes these things are holographic. 94db spikes and I didn't even realize it was loud. we'll see how this continues to flesh out. thanks again for the ideas. I will review more on the quicksilvers. I would still appreciate anyones direct comparisons b/w some of the amps that were recommended.

Oops. Spoke too soon. Ran out of gas with my 60w. The sound is glorious though, just won't reach 100db. Close though 98.9. Btw no I don't listen at those volumes, but I do listen at 90. At 90 there are peaks at the top of what the Sixpacs can do.

I can tell you I have replaced a pair of pass XA100.5's after A/Bing them agains the M180's. I feel pretty confident suggesting the M180's. I can only imagine what a pair of Apollos sound like!

I am reading that rogues are hard on tubes. At their used price I might be willing to try them, but not if I will be retubing frequently.

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?
