Atma-Sphere MP1 with single-ended inputs and outputs? Adapters OK?
You can use the adapters or have an XLR > RCA cable made. Another option are these which I use: http://http//  
Has anyone considered rebuying a speaker you once owned??
Just repurchased a pair of Spendor 1/2e speakers and they are everything I remembered them to be when I sold them 7 years ago. I alternate listening to them with Quad ESL-57s. 
Recommended Speaker List for Atma-Sphere OTL Amplifiers.
I have had a number of people listen to my Jazz Modules. One in particular who is pretty well known in the audio world mentioned that they sounded better than the German and other exotic horns he has heard. If you do visit Duke and hear his speake... 
Balanced v unbalanced input to Ayre preamps
Ralph's (Atmasphere) comments regarding a differential balanced circuit eliminating cable artifacts is based on the balanced design supporting the 600 ohm standard, as Atmasphere designs do. It is my understanding that not all balanced designs sup...

I use M60s and an MP-3 in my system first with Audiokinesis Jazz Modules and now Quad ESL 57s. I’m getting a pair of Spendor 1/2E speakers to use with them as well.Dealer disclaimer.

Dearly departed Music Reference RM9
The RM-9 MkII that is listed on this site for $2600 is a great deal and worth stretching your budget for. It started out life as a MkI but Roger went all out to update it to a MkII. If it makes any difference we will honor the warranty on that amp...

I still may have it. Be patient while I look for it. 
Solid State Amps for Quad ESL 57?
That is an interesting set up for the ESL-57s. The Dynaudio subs sound interesting as well. I may look into them a bit more. The spider legs I have do use a three leg approach like the original. The back leg is affixed in the exact position as the... 
Solid State Amps for Quad ESL 57?
Chris,Sounds like a nice set-up. What subs are you using? My room is 12' w x 18' d and there is a lot of stuff taking up space. So I am pretty limited in placement. I have them about 4' out from the front wall and they are on wood spider legs so t... 
Solid State Amps for Quad ESL 57?
George,Interesting you should point out that Pass design. About 20 or so years ago N.E.W. loosely based their DCA-33 amp off the A-40. It was about 25 watts Class A and used a separate battery (lead acid) power supply. I owned this amp along with ... 
Solid State Amps for Quad ESL 57?
Chris (ct0517), I believe the RM-9 is no longer available, even as a special order. I could be mistaken however. Roger has relocated to the Bay Area, and appears to be more involved in his Audio Engineering school than in running Music Referenc... 
Amps that Mate well with the Lightspeed Attenuator (LSA)
I have used it with a Music Reference RM-10, VAC Auricle, Atma-Sphere S-30, and have heard it used with Coincident Frankenstein. As George said make sure the impedance requirements are met and use low capacitance cables. Personally the Music Refer...

What is the best OTL out there?
I run a set of Atma-Sphere M-60s with my 57s. I ran them alone for a while then added a set of Zero autoformers in between them. Use the 2x or 3x settings. Nice improvment.
