Pre Amps

pubrunner2000 · 4th January 2006, 01:18 PM

I have recently acquired a Leak Stereo 20 and no less than three pre amps. All appear to be in excellent working order.

Question is, which pre amp would be best to use with the Leak ?

I have only tried the Counterpoint SA7 (which appears to have a LOT of gain) - does it need to be used with attenuators ?

The other pre amps are a QED Passive and a Glen Croft Super Micro Stereo Valve pre amp. I am unfamiliar with all of this equipment and would value any opinions on which to keep with the Leak and which to dispose of.

Best wishes,

Andy Heaton

The Leak has a sensitivity of 125mV for full power which is far too sensitive for anything but the weediest tuner. Unless you need a phono stage, I'd use the QED passive. Otherwise, the Croft should be good.

Hi pubrunner2000,
I agree completely with EC8010. Lose the Counterpoint, it should bring some money.

To prove I'm not biased against the Counterpoint, I was authorized warranty service for them in Canada. I also have a Leak Stereo 20 that I'll be restoring (soon I hope). I also have the matching Point One preamp. Later, why not build your own?

From my remembering the Croft has no gain, White follower as line stage.
