Best amp for Martin Logan Summit X

Hi All,
I need a new amp for my Martin Logan Summit X electrostatics. ML doesn’t offer advice on this, so I’m turning to us. I am thinking of the Sanders Magtech, a used Plinius SA 102 or 103, a Jeff Rowland Continuum or Plinius Hautonga integrated. Maybe a David Berning ZH230? Any other tubed amps I should consider? I know there are probably many more; I want to stay under $5000. Any and all help will be appreciated.
By the way, I have checked other forum threads and not really found much help.

Ones that are totally comfortable seeing 1ohm all day, and don't sag in their power delivery into it, many that use tubes get distant sounding highs for this reason.
Out of the ones you mention only the Magnatech has a show of getting the very best from these, the others will work but the speaker won't give it's best.

Cheers George

+1 George! Sanders Magtech is the best choice for ESL's!

Yep out of that lot the OP put up it is.
But there are probably better than that for ESL's that have down to 1ohm loading for similar pricing.
Over at SNA Australia they did a shoot with the Summit X's and the Magnatech didn't fair as well as some others, because again of the 1ohm loading. 

Cheers George

Hi Rustler. I have a pair of ESL-11A's and have been running an ARC Ref 75 amp. After a lot of investigation I have realized that I am not getting all that I can from these great speakers. At a 4 ohm rating, like yours, they need more current to  make the top end sing. I am awaiting delivery of a Luxman L509X that mates exceptionally well with these. Good luck.
