Seems like a lot of folks are putting their Primaluna amps for sale...

PL is relatively high volume sales, percentages of sells to buys would give much more accurate picture. I had Dialogue Four with many diy mods, sold because I prefer my much more expensive SET amps. Still listen to this amp in nephew's system, very nice setup for his first system.

I'd imagine most are selling because they're moving up, similar priced amps and pre's are going to be sideways move at best.

Yes, but it’s proportional to the boatloads sold.

PL is pretty good for the money... I demo'd several pairs of speakers with them and I thought they sounded great.... but then I thought about how great my Quicksilver amps are and they were half the money and twice as good.  Built in USA and built to last.    

PL is okay and that is it, just Okay.

I've got my cheapo Prologue One cranked up at the moment, listening to Wagner's Lohengrin from an old Angel/EMI LP.  Lovely vocal & string tone. 3D. Enjoyable if not shatteringly effective dynamics. I could care less about upgrading.
