Aftermarket Power supply’s with Martin Logan ESL

I realize this is an old post. but i use the iFI power ac/dc ( 15/16 volt ) adapter for my Martin Logan Classic 9. They do sound much better than the stock units.

Thanks for the votes of confidence! I was worried the ac adaptors from Isi would pass the full 1.5 amps to the Logan’s and might fry something. 
It could be all in my head but I swear it sounds better! 

Your ML speakers only draw less than .4 of an amp.

Not even, 10 x less. More like 5watts for both, and that’s for the big CLS-IIZ’s

From the CLS manual:
" Will my electric bill go ‘sky high’ by leaving my speakers plugged in all the time?" 
"No. A pair of MartinLogans will draw about 5 watts maximum."

Cheers George

No problem with using the ifi . The 1.5 amp designation means that is the maximum current that can be passed by the ifi device. Your ML speakers only draw less than .4 of an amp. So you are plenty safe using one ifi per speaker. In fact at its 1.5 amp rating the ifi can power two ML speakers safely.
