If you don't know tubes, I'm against vintage for you. Too much tweaking and maintenance. You easily can find a Jolida in that range. All you need is 8 watts per channel with Klipsch. 40 watts will make them scream. Another solution is a pre and power combo with the pre being tubed? I know of an AR SP2C and PSE studio IV (class A) that you could get in your price range?
best inexpensive tube integrated
I just bought a pair of klipsch heresy speakers in mint condition for a bargin. Ive always wanted to experiment with tube amplification and I think now is the time. I know very little about them(tubes) and want to try them out at a minimum of expense. I paid 350 for the speakers and therefore would like to keep my budget below 700 for a tube integrated. I am not against used equipment. Is it worth a try or is my budget too low to jump into tubes? suggestions please!
