Help me please!!!

So you're going to buy one of those very expensive amps unheard? I would call that a pretty bad move considering their respective price ranges. Asking folks in a forum which amp to buy may make you feel better but its not a panacea, please take the time to audition before you make a purchase like that! Sorry if that comes off a bit harsh just would hate to see you make a very expensive mistake.

Jond, the main problem is that living in Ecuador it’s imposible to make any audition. I think, I’m the only “audiophile” around...

MM3 and Dartzeel is a classic combination -- have you spoken with Jonathan Tinn at Chambers Audio? He demos this combination at shows regularly and is also an excellent person to deal with

leog2015 I see well that totally changes things but I agree with folkfreak a good dealer with experience with the brands would be the most helpful. I wish you the best of luck and hope you end up with an amp you love!
