My Magnum came with Electro Harmonix tubes. Think it was 3-4 years old when I bought it. (store demo) Guess they switched. The EHs aren't that bad for new stock. Not as quiet (or detailed) as the Sylvania NOS in there now, but not bad. I know from speaking with Mark O'Brian at Rogue that he was never really happy with the EHs. Top notch company to buy from. Mark can put up with my constant questions! New NOS for the phono stage coming! Diana Krall is singing in my living room. Awesome.
