If you are looking for a PP tube integrated, there are many, but the ones i favor are all in the 12-30W range: Leben (Japan) makes two, the CX600 (6L6GC) and the CX300(EL84) and so does Audio Note (UK), the OTO (EL84) and the SORO(6L6GC). The last 2 are available as SE amplifiers, as well. Of these 4, the one I like the best is the OTO SE version, the OTO Signature with double C-Core output transformers. They also make 300B integrateds, the MEISHU, MEISHU Silver and MEISHU Silver Signature. I've owned the Silver model and enjoyed it very much. Up the line are a series of 211 integrateds, starting with the Jinru at about $25K and then up.
