H.T. Processor witch is better in sound...

OP does not provide enough information. If the choice is just between the two processors and acoustic room correction is wanted, then It's probably the Anthem, because ARC was a major bug in the Cary 11a and likely to be in the 12 -- the Cary 11a manual recommends a tape measure and SPL meter. If OP's sources are discs, computer, and cable/satellite, then Oppo 105 analog direct to amps might be a better choice than either processor, because it can do lossless codecs, speaker configuration, bass management, volume control, and so forth. It doesn't take analog input, e.g., from a from a phone stage, but it can switch among digital sources.

I will do more research on SSP-600 and 800.I will be changing some time this year.

Room correction is wanted...

Cary does not use ARC (all caps) which is an Anthem trademark. It does have some proprietary room correction about which there is little enthusiasm.

In that price range, you might also look at the Krell Foundation.

Krell Foundation have lots of option and 10 HDMI input and 2 outputs. What I've been reading about it,you almost need the dealer for set up it is complicated and there no dealer around etc...So the battle would be with Anthem that got a lot of bell and whistle and Classe SSP that got the best sound on the reviews.I will do some searching during the year.

If anyone have more info about HT Processor it would be appriciate.
