Life after DarTZeel

I would like to hear from ppl who have had and SOLD DarTZeel amp.

I'm asking ppl who have already sold this amp, since very often, when we still have the stuff, we either do not want to admit its shortcomings, or just don't hear them. It is only after buying sth new, we discover what part of the performance could have been improved upon.

So what was your next amp ?
What qualities your next amp exhibits that DarT lacks ?
