While the 'best' of anything likely does not exist, the musically most satisfying amp I have auditioned this far, regardless of underlying technology, is the new Rowland 312. See my further comments on this device at:

Please note that there exists a vast sonic difference between the 312 and the lesser Rowland 501 and 201 monoblocks. The significant price difference is in my own view fully justified.
