Finally understood why people like tube amp so much. I went a serious listening test this weekend by hooking up the amp with the M22, M40 and M80 to do some comparison. None of the speakers dispointed me but I will rate the M80 first, M22 second and M40 the last due to the fact that the M40 provided a tag too much of the bass. Don't doublt about this little baby, it can really deliver punches, it may the M80 sing like a fat lady, the mid is accurate, the high crystal clear.
Now, it make me wonder if I get a set of tub pre/pro, will it give me even better sound?
