If your room isnt too large I wouldnt bother with either, Ive tried the 390s direct and it sounded lean with the Mcintosh. The new silk tweeters on the Duette would sing with tubes and I think the Mcintosh MA2275 integrated would be a better choice. Others may disagree but for my taste tubes just cant be beat. If you have the budget swap out the stock kt88's for gold lions, and the 2 12at7 with a pair of telefunken ecc801s. Good luck!
McIntosh MC252 vs. MC352
I'm looking to purchase one of these McIntosh amplifiers-preowned. They are approx. the same price (<$3K). Outside of power (250-wpc vs.350-wpc), which one sounds better? I'm planning to run a Mark Levinson 390s (CD Player w/built-in vol. control) directly into the Amp., then out into a pair of Wilson Duette speakers. Any guidance would be greatly appreciated. Again, sound quality not quanity, is most important.
