Jeff--Never heard the Tonians. Look great.
Received the LP3a, yesterday, and am running it in, today. Came with JJ 6sn7 inputs, a Sophia 6sn7 output, and a KenRad 80 rectifier. Supposed to be able to take 6sl7s on the inputs, too. Sounds much different from the LP27a, but I suspect that has mostly to do with the fresh new production 6sn7s over soggy, but lovely, 80-ish year old mesh plate globe 27s.
For anyone that bought new, did you find significant change with burn it (of the unit, rather than the tubes, assuming an early roll)?
