Almost every tube amp designer I have talked to likes the M20's with SET's - it's really more impedence than wattage. Plus that three to one tube ratio in watts. Thirty is more like 90.
Audio Physic Yara vs. Revel M20
Has anyone compared these two, or have experience with both. Please give you opinions. To be used with a 30 watt tube integrated, Nottingham TT, and a cd player. Small room, maybe medium. Thank you
