I also own Martin Logans (the Quest Z's) and went through the same problem. The system was too bright with Krell and Ayre had me climbing the walls. After many amp auditions, I found a great matchup for my Quests. I listened to a BAT VK-500 with Batpak and knew right away they had the right synergy. To further enhance the sound, I used a NOS upgraded Sonic Frontiers Line 2 and added Shunyata Powersnakes power cords to the system. This combination has been outstanding. The speakers are no longer bright. The MLs love tubes and they deliver excellent transparency with a soundstage that spreads far and wide. Needless to say, I love this system. Hope this info helps.
Best amp for Martin Logan CLS
I have a pair of original CLS's which I am driving with a PS audio 200c amp. I would like to upgrade the sound. The bass is handled by old Entec powered subwoofers. What might be the best amp I could upgrade to. The speakers sound a bit bright and I'm afraid of solid state amps making that worse. Has anyone matched these with a Krell 600 or would tubes be the answer to a warmer sound?
