I guess, there is no "best" out there. One prefers Transistor, the other one a Tube amplification. For each Design there are good and average Designs available. I guess endless average ones in general.
There is no other stage in the whole System where you can win or loose so much.
Anyway, I have a highly modified Lamm LP2 with very special Transformers and lots of selected better parts than stock and this one is by far the best unit I every heard.
Pretty useless for you I'm afraid, but a 2.Hand LP2 is easy to get and hard to beat, but depends on the rest of your System to bring the best out of it.
