Best amp for ML Z Quests?

hello Ron, I am a big fan of Levinson and Krell, but I have to warn you not to use it with your Martin Logan. On the other hand, I am not an Audio Research fan, but the only time that I've ever heard "jaw dropping" sound from Logans was with AR. It was with Classic 150 or something. I am not familiar with their models, but it was around $10K for the pair. if you use Krell or levinson, you will be very dissapointed, anyone who tells you otherwise haven't heard the ARs mated with Logans.

I have a pair of ML SL3's. I used to have a Musical Design 140i amp. I purchased a Meridian 557 power amp(200 Watts 8hm and 340 Watts 4hm) I have never looked back. The Meridian is a warm British amp that has been OVERLOOKED by the media.In fact I have upgraded to ALL Meridian front end components!! Steve

I own Quest Z's, have for a long long time now. I've tried various amps with them, so far the best match is a BAT VK-500 with the optional BATPAK. I haven't tried tube amps mostly cuz I don't wanna invest in new tubes on an ongoing basis, the BAT sure does the trick for me. Oh, cables make quite a difference as well; I use (2) Harmonic Technology Pro AC11 power cords and Transparent MusicWave 10' Bi-Wire speaker cables (spades). I'm very happy with the set up, and at $2200 used the BAT is a great value. If you'd like a better understanding of my set up drop me an email and I'll provide more details. Happy listening!
