As a 500 series owner, I`ve been waiting for Room Correction/Digital EQ before I move to the 800 series. Without RC/EQ, the 861 is just not worth the price of admission (to me).
I`m also disappointed that the promise of the RC has been out there for years now with no delivery.
If I were to put out ~$10K today, I`d get a TACT TCS, and keep my 565 for it`s music modes.
I heard the TCS at CES this year, and man, it`s the most substantial audible improvement you`ve ever heard!
All other features pale in comparison.
I have a custom designed and built dedicated HT room, with RPG treatments and the whole nine yards, but I`m positive RC will be an audible improvement over what`s already there.
I`ve come real close to buying a couple of Tact RCS`s, but the promise of an 861 with RC keeps me waiting. But not for much longer…
