Why is there no love for Prima Luna?

Because Prima Luna isn't that great, even when there are many worst ones (try Line Magnetic, Ming Da, etc)

Say, if Grand Hotel Tremezzo charges you 75 euros a night to stay in their storage closet, would you call this "a great deal", "excellent value at this price point", "best bang for the bucks"?

How about an $100 Yugo?  Would that be "great buy at this price point"?

I once heard an all top-of-the-line PL setup (driving Maggie 20.7 or something like that) at my audiophile friend's place for hours.  He tried all genre of music to impress me about his PL line up.  I truly don't understand the humor.

Can "Made in America" brands (really: assembled in America) actually claim that every last strand of wire, every electronic component, and every connector was manufactured in the US?

Sez who? Prima Luna Rocks! Stereophile puts it Class A. I got Dialogue Premium HP Integrated and with the right tubes it is excellent. Drives a variety of speakers I've tried just fine. (Maybe the electrostats not so much.) Right now I have it with Revel F226Be (86dB) and it hangs in with the 4 other pretty decent systems I got going.

I bought a lightly used Prima Luna Prologue Classic about 6 months after they were released into the market for about half the price of new. I couldn't be happier. The only mods have been tubes; KT120's and NOS 12AX7 and 12AU7 tubes. I have used the Prologue Classic with a wide variety of speakers and currently have them paired with a set of ProAc's. All have sounded very nice with it. I have never had a single negative issue with this integrated amp. It sounds as good or better than most of the $2000 amps I have ever listened to. There are better integrated amps out there, but you have to pay more for them. I just choose not to because I like what I have despite the fact that I can afford much more expensive gear than I currently use. I really don't care if the amp is designed by Dutch engineers to exact standards and manufactured elsewhere. It's a global market whether we like it or not. 

@cindcyhound....I have the PL Dialogue HP mono’s (EL34), PL Dialogue Premium pre-amp with Wilson Sophia II speakers. The sound is outstanding IMO and I have no plans on upgrading. I listen to 70’s classic rock, bluegrass, jazz & blues. I think the speaker effeciency is around 87 Db’s. I listen to most of my music in mid to upper 80’s decibels which is around the 11 o’clock position on the volume knob. The PL’s replaced Cary V12 mono’s and SLP80 pre-amp and I much more enjoy the PL’s. Hope this helps you.
