Anyone own or heard of PrimaLuna?

Oh yeah. Slept well. Engine starts again.

Seriously, it's hard to differentiate now. The more I play the mc601, the better it sounds thru the C1100 on PSB T6. I used to play it with Marantz AV8801.

it seems PL and MC601 sounds pretty similar thru C1100 tube pre.

I like both but only to keep one.

BTW, my main channel will be shared with home theater, will it be fine to run tube amp for movie?

In my opinion, the two components that you compared are suited for (completely) different applications. They might sound "similar" at lower listening volumes driving relatively efficient (and moderately sized) T6s but the MC601s have the potential to drive a significantly wider range of speakers. If price (and space) are not considerations, I would definitely pick the MC601 for home theatre application, especially if you like the "warm" McIntosh sound. Besides, it's probably a much better match with the C1100.  

Does PrimaLuna make any balanced Amps?

PL doesn't have balance amp.

I just performed a blind test on my wife. Using PrimaLuna Premium HP and MC601 with PSB T6 and Wilson Alexia.

She likes the sound from PL on both speakers. She claims both speakers sound smooth and deeper bass than MC601 where she think it's too bright (too high frequency). PL is much more comfortable to her ear.

When I swap both speakers around using the PL, she claims she couldn't notice any different!!! SERIOUSLY? OMG. I save the money for 3 years and got something she thinks it's the same than the speakers I got back in 2006!!! OMG OMG OMG OMG.

Anyway, the point is PL is pretty darn good. I am going to commit to it. Thank you guys.
