Why is there no love for Prima Luna?

"This is actually a thread in disguise to plug Prima Luna. Get the happy owners to come out and respond. Brilliant! I knew it was gonna go sideways reading the thread title."

I can only share my experience as I own them and it so happens I'm happy with them.
I would think a thread like this would also be an opportunity for the unhappy PL owners to voice their issues with PL as well.
I'd like to hear from them, and I'm not talking about system synergy issues.

Lumin is made in China and so is Line Magnetic! Both best bang for you buck and very well regarded in the US. Outside of that I have not used any admirable Chinese audio products! 

Proud owner of a PL dialogue primum HP integrated.  Bought 3 years ago and sounds amazing with my easy to push Klipsch Forte III’s.  Never had any issues, wonderful little robust, well made piece.  Couldn’t be happier!

Based on this discussion, what is the price range you are willing to spend and what are the top five within that price range this group would highly recommend and why?

I have love for PL . I had two PL HPs and sold one and replaced for a Roger's High Fidelity to better drive 86 db speakers. The one I kept drives 92 db speakers. 

Like with so many things if the AMP/speakers mesh well then sit back and enjoy the music.

Also PL is no longer the new kid on the block so maybe that's what the OP is picking up on. The latest and greatest may be better or just more noise. YMMV.
