What is a good amp for my ML Aerius I's.


I am currently using a Aragon 4004 Mk11(which I like). Would any of these amps: Marsh A400, Aragon 8008, or the Innersound ESL be a significant improvement over what I already have. I will consider other options that do not break the bank. I am particularly interested if the Marsh excels or starts to fall down when presented low impedances presented by ESL's. I would greatly appreciate responses from people with experience with electrostats, as I am aware some otherwise good amps may not fair well with ESL's.
FYI my pre-amp is a CJ PFR.

Thanks in advance for responding,
Bryan

Agree with Jeff above...found the "Logan's" to enjoy both a Clase CAP-100, and a Classe CA-300/CJ-ART combo.
I heard an Audio Research VT-100 MKIII along with a LS-25 preamp on a pair of ML Prodigy (current pigs)... 100Watts did the trick (and was pretty impressive also)...

It may be out of budget but look for a used Vt-100...
I would save my money and stay with the 4004 if you like it. The Marsh will not be better - the 8008 will not be better than the 4004 with these speakers. I own and have owned ML's Aerius, Quests and Odysseys. The Innersound amp would be a good choice if you want to let go of more money - maybe if you upgraded to the Ascents or Odysseys later but if Aerius is doing good for you with the 4004 - buy more music - too often we spend money needlessly on stuff instead of music which is really suppose to be why we have the stuff.
ML's are current hogs, I'd suggest you consider Classe. Along with a tubed preamp and the right wires you have a marriage made in heaven. Jeff
I own and sell electrostats, and tried an Aragon amp with my stats and found the sound to be a little on the thin side. I haven't tried the Marsh amps. After a bit of shopping around I chose to become a dealer for the InnerSound amps, so I guess my vote is fairly predictable. InnerSound dealers are typically quite willing to provide an in-home audition, so if you have a local dealer see what he says.

Best of luck to you!
