Electrostatics and tubes


I am looking to get some new to me speakers,  I've been looking at options and would really like to try a set of planars "electrostatics".  I have read or heard somewhere that as far as speakers go they tend to be inefficient (85 to 89) vs.90+(db) on the Klipsch or Dali's I've been tossing around as a standard speaker option. I guess my question is would I need to worry about any over heating issues. I plan on using plenty of power with a set of VTA, M-125's to power them. I am looking at a lower budget set maybe Martin Logan ESL 9's or Magnepan 2.7i .    Just wondering I would hate to over heat a few hundred dollars worth of tubes if I don't need to.   ¯\_(ツ)_/¯  don't roast me to bad I cry easy wink  thanks.

With my ML ESL 11a speakers, I use an audionet V2 amp 250 amps into 8ohm 450 into 2ohms. Works well for me. Tried a premluna tube power amp, preferred the solid state. I think you need to try a few differnt amps to find the sound you enjoy.

I’ve owned 10 different types of Martin Logan’s for 32 years. From 3 different sets of CLSiiz’s to Summitt X’s. The story of current ML’s being inefficient is tied to the fact they were 20 years ago. Not anymore. So buy your 9’s and simply enjoy them. Cased closed. 

MartinLogan ESL speakers highest current draw is in the highest frequencies where there is usually minimal recorded sound which make them easier to drive than expected. Currently driving my ML-11a's with a Mcintosh ma352 with no issues.

 

Steve Guttenberg followed up his review of the Eminent Technology LFT-8b with a review of the new LFT-8c. In the review he gives his opinion that the 8c is a significant upgrade from the 8b, and that he considers it superior to all Magnepan models, and all ESL's (of which he is not a fan). Here it is:
