the mccomack dna 750m can run revel salon2 ?

The DNA750 Mono amplifier has an output power rating of 650 watts into 8 ohms , 1000 watts per channel into 4 ohms.

If that is not enough power for a pair of revel Salon 2 speakers (or any speaker for that matter).... than the speaker is not worth buying or producing for that matter.

Quantity wise, it is more than enough. Quality wise, you will be the one who can tell.

Had my dna750’s for a few years now.
they have become much better with age, and when left on for 24-48 hours.   Dan Babineau swapped out most capacitors with Teflon and as much as I listen to them, they seem to get better every time I listen to music. He said those caps are probably not broken in yet.   I bought a lucky pair with most caps replaced by Dan with Teflon capacitors.
