Wow that is indeed high praise. I'm curious in what way did it improve on the what your b15 did?
At the low end, particularly a low B. That was never any of my B-15's forte. There's no hyped high end like many tweetered cabs with SS heads (but the highs are nice), it's smooth like the B-15's with similar punch that I loved with mine (I had at least three over the years). It sounds about as far from that stereotypical hard SS sound as possible. I was hoping the B200-R would build on that, haven't had a chance to check one out yet. The only shortcoming is hanging in a more than medium loud mix unaided. B-15's have the same issue IME.
BTW I set the tone controls at 5-3-3-5, turn the voicing switches off and it's happy time
