Well, Ralph is on the forum, so either PM him or wait to see if he'll respond.
Of course, you can always call the shop directly. He usually answers the phone.
I agree with @soix, his amps are known to work well with low impedance speakers.

ATMA-SPHERE MA-1 MK11.3 with magnepans, am I completely mad?!
I have a pair of magnepan 20.1, which I run active. I user a pair of 600w amps on the bass panels and then I use 80w KT88 monos on the mid-bass + tweeters.
I am considering buying a pair ATMA-SPHERE MA-1 MK11.3 silver edition in lieu of the KT88 monos.
The maggies are a 4 ohm load and I believe that they are a pretty "flat" 4 ohm and don't dip below that.
The ATMA-SPHERE MA-1 MK11.3 are 140w so I think they could be a winning match, but what do you think?
