I have a Modwright KWA120SE that I use in the summer instead of my tube amp. My speakers are Zu Omen Defs. It is sort of tubey sounding. It's both sweet and clear and rounds off the leading edges just a little. I like how it separates instruments and vocals from one another and the feeling of effortless power.
I just put it back in the system at the first of the month and it took about 3 days to settle in(about 12hours?) after sitting idle for so long. Of course it's missing the nuances that only tubes can do IMHO.But it's not dry or harsh ever. Hope this helps as you ponder your next move.
