JM Labs, Altos or 946

I have auditioned the Altos & the Novas, I had a hard time telling them apart. My 2 cents worth. I think the Mezzo's out preform the Altos. More natural, warmer sound. I found the Altos a little harsh. I also feel the Mezzo's have a fine detailed bass. I was sold on the Mezzo's until I heard a pair of Revel Studio's which I ended up putting into my system. Are you sure you would want to give up the 1201 mono's for a tube amp? I think you would lose a lot of punch and speed that you have now. I came very close in doing the same ( 1201 mono's out of my budget ) going with the tube amp. I decided on the MC352 and the C2200 (tube) preamp. This combo gives me the kick I want from the amp and the warmer sound from the tube preamp.

Thanks for your response Dave. Switching the 1201's was just a thought, didnt think I would need all that power with the Altos and I always wanted the MC2000 as a collectors piece, will definatly wait till I hear the results with the 1201's first. I too have the C2200 and using an EAD pro 9000 dac with the Mcintosh 751 transport. Going to audition the 946 early next week, dealer is asking 6k for a demo pair. What are mezzos going for anyway? Thanks, John
