I've owned one (actually a pair at one point run as monoblocks). It was 5 years ago or so, just when they were starting to gain favor in the audio press. So I don't know how much that can be translated to current models.
Smooth sounding, especially if you kept to low watt usage (it ran out of steam quickly on speakers that were even moderately difficult to drive). Didn't have great detail (kind of warm and fuzzy sounding in stock form), laid back sounding, which was good if you had a bright pair of speakers. Bass was a little mushy with them and definitely lacked deliniation. And that was in an absolutely perfect acoustic space.....hmmmmmm... man, I miss that listening room.....
It wasn't bad for the money at the time, but there is a lot of other stuff out there that I would take over it nowadays. There were several people doing mods to the amp that supposedly greatly increased its performance. Again, these thoughts were on the amp that I owned more than 5 years ago. I think, if I remember correctly, that they did revisions in subsequent years.
Just my non-commercial opinion having owned the amp long before I ever started a business. Take it for what it's worth.....
