Why is there no love for Prima Luna?

Apart from the personal sourcing decisions of various people Primaluna offers good performance for the price and good resale possibilities. I had a Dialogue preamp and a Dialogue HP amp paired with Odyssey Kismet speakers. Sounded great.

I have a Dialogue Premium Pre and PL 7 mono blocks with KT120's into Tekton Double Impacts and am very happy.  Everyone (including some industry pros) who have heard my system were very pleased.  They are built like tanks.  Tube rolling on the pre made a world of difference.  Stock tubes sounded dry and brittle.  I bought everything used and Upscale answered all my questions knowing where they came from.

The only "negative" is Kevin Deal as far as I can see.

It seems that there is a lots of love for Primaluna from people who actually listen to it. That is what matters.

Perhaps the OP mistook the few available negative PrimaLuna posts as representing the population at large.  Perhaps there are a lot more satisfied owners that simply are not posting maybe because PrimaLuna is a relatively established company so much has already been written/posted about their products.    
My experience has been the opposite of the OP - most PrimaLuna reviews have been positive with most agreeing that the engineering, quality parts (not cheap), quality build (again not cheap), and point to point wiring (labor intensive- expensive) make PrimaLuna a good/great value at their price points.  
Although the China comments were a bit off topic, I did appreciate the thoughtful comments like from @jjss49.  People are people - we love our friends and families (warlike Klingons aren’t real), work hard to survive or get ahead, and are less than satisfied with our governmental performance....or lack thereof...
