@tooblue ."..but did not keep the amp long as it was not a good fit for my system."
tooblue, if you can share more - was it lacking drive or dynamics in any way, when paired with less efficient speakers by chance?
I ask because I have been working with a few different builders to decide to scratch build another set of lower power EL34 monos close to Will’s spec. My primary speakers are 93db/1w efficiency. I listen at LOW volume levels mostly. I don’t want to have to turn it up a lot to hear it. I won’t be replacing my speakers. I may be asking for too much out of these pseudo type EL34 amps. Any thoughts on yours, how and why you moved on...?. Thx.
