@will62 .. I think you made a good choice with the TubeCube 7. A while back I purchased the APPJ PA0901A ($180, now discontinued). I believe it was APPJ who originated the design and licensed it to Tube Depot (and others). I used it for about 6 months before rolling the tubes, which made a big improvement across the board. IMO this little amp sounds much, much better than it should. I purchased it as an introduction to the SET/SEP world. After living with it for a year and being sure the SET approach was for me, I placed an order for a Decware amp. The little APPJ went into storage. I won't be getting rid of it, surely it will be put to good use again at some point in my future. Best of luck with your new amp. Sorry for being late to the party.
