Sophia 300B vs Jeff Korneff 45 Amp

Anyone have anyway of describing the sonic differences between Sophia Electric 9101 300B monoblock single ended amps and a Jeff Korneff 45 SET amp? (Let's assume the JK 45s have enough power to drive the speakers at around 100dB efficiency.) Thanks

- a related question would be which tubes would be preferred, Sophia, EML, solid plates or mesh plates, etc

My experience has been the bigger the tube the bigger the sound......

My experience is that power kills. The 45 or the 50 tube is the best output tube for SETs. You just have to have the right speaker. High efficiency,low driver count,benign impedance and the 45 will walk the dog!

Jeff K build quality's far higher. 45 will limit what you can drive. But for your use a JK 45 Is the better sounding choice. Still why Sophia 300b? Far better 300b amps about.

Hi Philefreak, Thanks - When I look at the Cornwall II I think I count 3 drivers - is that going to be an issue with a 45 amp? (The specs say it's 8 ohms, but I'm not sure if about how that applies across the frequency spectrum.) Thx again
