Interesting
I thought everyone was a fan of Harmon's stuff, at least the HK stuff.
Funny, I went from a loyal Onkyo fan (my first receiver) to Harmon Kardon and haven't looked back. I had an old Onkyo with 60x2, 20x1, 15x2 power, back in the days when Dolby Pro Logic was IT.
I loved that Onkyo, and it served well under heavy use for years and years and years. Then I got an HK AVR 225 (55x5) and there was no looking back, I preferred the HK's. Then a AVR 330 (55x7)? I think, didn't keep it long so I could upgrade to a 635 (75x7)(gave/donated the 225 to my parent's house, sold the 330 on Ebay).
The 635 did have some minor issues, sent it in for warranty work, and they mailed me back a 745 (85x7) free of charge on the upgrade (though I did have to wait about 1-1/2 months w/o a receiver; we'll worth the wait for the free upgrade!).
The 225 still serves my Parent's house loyally; so they do last and last. I've been keeping on eye on Denon's when they go on sale or clearance. Always favored Denon, HK, and Onkyo for AVR's over other brands.
