have been waiting a long time for this after the previous shipment of 110 volt. When by chance will the 220 volt be shipped. The world is bigger than the USA although some may disagree with this statement. ;)
I almost bought this but unfortunately it is a Push Pull design which lacks even order harmonics. That means that even though these designs give you more tube watts for your dollar, they have much less tube euphonic sound which is the even order harmonics. You can google this yourselves.
That's a very narrow view of SE vs. PP tube amps. Many highly regarded tube amps on the market today are Push-Pull designs...both types have pros and cons..
Sorry about the late response. I'd expect that this amp would have no problems with the Motion 15s. It has been driving my 88dB JBL Studio 570 speakers rather nicely. I wouldn't use it in a large room, but for a bedroom or small living room it gets rather loud.
