Hello, Anybody know of any great tube power amps, for less than 0. I dont need much power (5 watts is plenty). I listen to metal and rock so i like a good, tight dynamic bass. I am using Klipsch RF-62's that have a sensitivity of 97dB/watt so even 1 watt is probably enough. These speakers are very clear and revealing so i figure a nice warm tube power amp would be great. I mainly listen to cd's with an occasional record.
