sean619,
I forgot about the MP301. Everywhere I've read it gets good reports, and it appears to be a great bargain, and yes it's price is considerably less than the Glow, even with the Glow on sale.
Point to point wiring has 4 advantages over PC board mounted tube sockets, not that any of them are necessarily a deal breaker:
1) No heat bleed into a circuit board from the tube sockets.
2) No flexing of the circuit board when tube rolling, as the tube sockets are chassis mounted.
3) The point to point wires are likely a larger gauge than the traces on a circuit board, not to mention much more robust.
4) Point to point wired amps are easier to modify.
Keep in mind the Glow Amp One is an $840USD amp on sale at $580USD whereas the MP301 is about $350USD regular price. I will hazard to say the Glow is in a different class than the MP301 (having never heard the MP301).
Also, output transformer size is not everything, but design is. Decware's OPTs on their low powered sets are quite small compared to some other brands, but to this day they are my reference how an amp should sound - absolutely incredible.
