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

It's probably to upgrade in some instances. They get good reviews, but they aren't perfect according to user reviews; they are built to a price after all, and I have personally always thought that they were ugly for tube gear. 
Admittedly, I have never heard any of it, and as another poster says, it may just be to get some needed cash. Anyway, they sell a lot of them, so there are a lot of owners out there.

Probably just a reflection of good market share for Primaluna and Audiogon being a good place to sell tube gear for top dollar.

would agree with Tablejockey. great time to buy stuff. Am doing same, looking for good deals. 0nce covid is over, economy will come back strong for many. Lots of pent up demand right now.

There may be a few sellers trying to  raise rent cash,  but think that is more exception than the norm. If you look at historical data off hifishark, long before covid hit, there was a high frequency of regular primaluna sales. Its easy to see why some want to move up. Where else can you get a real tube amp new at that price? I know I bought my first PL amp on a lark.

Have owned VAC, Cary, CJ, VTL and many pieces of MAC gear, and have to admit PL makes it super easy and effortless to run tube gear on a daily basis.

I bought the PrimaLuna Evo 400 integrated and have been very happy with it. It makes beautiful music through my Salk Sound Song3 speakers.

A couple days ago I saw an ad for a reasonably priced Jadis Integrated in the my latest issue of....was it Stereophile?  The mouth watered.  Should I chuck my 'Luna, now several-years-old?  I remembered how superb a Jadis Integrated sounded when I heard it at Brooks Berdan's store, a couple years ago.  Then I switched on the Primo Luno to play a couple LPs.  I stopped caring.
