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."
