They are ver.3 in HG Cherry.
I have had them for about year half.
Only thing I can trade up to is M80 V4 or HP or the M100 etc.
I've owned the M22 and HK 750's and they were loud enough for that size room.
I will probably end up keeping the M80's for listening to music and the HK 3490 just need fond a MCA20 now.

Not sure about the distortion. That would have to be quite overly comfortable loud. If I had say the M22 and two or three EP500 ,do you really think they would distort ?
I am running a MCA50 as a three channel ext. amp
