Well my 604’s sensitivity is rated at 90dB, and has nominal impedance of 8ohm, but they do dip down to 3 ohm!
So we’re not exactly looking at an apple to apples comparison in load difficulty. But with that said, the 876 defiantly does not have a problem with driving my speakers to a high SPL for extended periods of time.(Tactile base just from my towers.)
The 876 is rated down to 4 ohms, so I feel pretty comfortable saying that it can handle your 2.5s.
Are your 2.5s crossed over with a powered sub, or are you running them full range?
How important is the video side of things to you? The 876 is extremely flexible in how you use the reon processor to process video, and it’s completely independent for each source that you have.
One thing that I do feel strongly about is the fact that Audyssey MultEQ-XT is superior to the Yamaha YPAO, and Audyssey
is a worth while feature.
The free extended warranty and free technical support from the Audioholics does make things interesting
