Best Integrated that you've heard under $5k

LFD LE MKIII. I liked very much! Still going after the years.

I was a dealer when PS Audio introduced the GCC series (quasi integrated), some 20 years ago. I bought the GCC 250 which I still have in my TV system with AV123 Swan 6.1s. IF it ever dies, my first consideration would be for a GaN based with dif balanced in/outs (as does my GCC 250) And while either the Marantz 40N or the Technics SU-G700 MkII, are both based on GaN tech, and both under $3000, Interestingly the Technics matching SACD player has XLR outs, meaning it doesn't connect to its own integrated XLR to XLR. This may not be a concern to many, but dif balanced is how I roll: my audio only system is 100% dif balanced

You will get many responses. The Hegel is the budget "sweetheart" to many I have not heard the current models but was not impressed with earlier effforts. Primare sounded better(at that time) but have not listened to Primare’s current class D offerings.

Cavalier Plus!!   And by far!

Right at 5k: the Anthem STR. There’s a reason that it’s still a Stereophile class A rec. several years after it’s introduction.
