Thoughts on mating ML ESL 11 A's to a butler TDB 2250 hybrid amp

Pvmike we used to sell the Butler amplifiers, they were a cool concept amp but sonically were not magical. 

The Parasound is good you should really  save up a bit more and go for a higher class of amplifier with those excellent loudspeakers.

What is the budget and the rest of your components?

Budget right now is about $2000. I am using a Linn Majik streamer dsm that has a 90 watt amp built in this will be my source and pre amp for the time being

I've owned a couple Butler 2250's over the years, along with a 5150.

Very, very nice amp for the money. Small company that I believe only sells direct now.  There used to be a small dealer down in North Carolina that gave decent deals on them.

You could likely find a bargain used, and send it back to Butler for their re-bias/update for about $300.00.

My neighbor has the ML 11's, and we did drive them with my amp a few times, it sounded really great.  

With the powered woofer, the Butler has the muscle and current to drive that panel, but the tubes give just a bit of that fullness that I think benefits a ML speaker.

It always ran at a reasonable temperature also.

Personally I think it give a lot of what the BHK amps are supposed to do at a much lower price.  With your powered woofer section it won't matter quite as much, but I think the Butler had every bit of the bass response as the BHK amp.

BK must be doing something right and he certainly knows tone.  He builds pedals for all sorts of the top guitarists in history.
