I don't have an over-all favorite; each amp has something that it does very well and something that it does "merely well".
For instance,with Analysis plus IC, I find the new SST series Brystons to be the best amps below 5khz that I have heard. I prefer them overall to the Levinson, and much prefer them to the Krell. The palette of tonal colors and shadings is very rich. Even my SET loving friends give them high marks on midrange. They are quite good in the highs too,with the right front-end and cabling, but other amps win out here.
Halcro impressed me mightily but bi-amping with much less expensive amps yields the same results.
The old T-series Threshold and the new Pass's are awesome on top. So, I am bi-amping with the "T" on top and the SST on the bottom. I consider that hybrid to be the best I have heard, including the Halcro.
Now, everything can change with a different speaker load so....YMMV.
