Martin Logan with Sonic Frontier Power 3

When I had a pair of Acoustat hybrids (like ML) I found they were grainy when matched with a Bryston pre & amp. I "warmed" up the sound by adding in a tube preamp so in this instance tubes were the answer. Since then I changed the speakers to Maggies and I am still very happy.This past summer,prior to changing my speakers and getting a tube preamp,I visited a SF dealer who also carried ML speakers. We tried the power 2 and power 3 with a pair of (I think SL3's, the 6 footers) and the power 3 did a much nicer job and so it should for the dollar difference. So I think that if you do not want to add in a tube preamp (which BTW I think you should try with the Brystons)the power 3 might just be the ticket. Just my 2 cents worth...

I have a pair of Quest Zs powered by a Krell KAV250 & experienced the sound problems as you. I put a Sonic Frontiers Line1 which really helped flesh out the sound but it still got a little bright on the top end so I tried a Pair of cardas quadlink 5c & got a really mellow sound.I have since traded up to a Line3 & Resolution REference cables all around & get a fabulous sound.Try to borrow a tube preamp & you might be very surprised.Should you decide to go in that direction it will be a lot less expensive.The sound problems you have may partially caused by the Wadia & a preamp will really make a difference. I am partial to Sonic Frontiers gear because it is sonically neutral.Good luck.

It is funny cause I was going to start a thread exactly for the same reason. Jfarkas, I have the same equipment well almost. ML ReQuest and 7Bs and yes they are edgy in the high especially at reasonable life like level. All my gear are the SF (Transport 3, Processor3, and Line 3 preamp) the preamp did help, also upgrading to Synergistic Research Resolution Reference all around did help, but still I was not satisfied. It get edgy at the top and too much at the bottom. I set my ML to the -3db bass set up, it was still a bit more than what I wanted, I moved the speakers a little bit apart. That did help in bass but not on the highs. So guess what, I ordered the Power 3.
