I have to agree with ADTG, based on your recent posts, you really should go for separate. There really is no separate for HT as such, the AVP is simply and AVR - power amps (functionally speaking, obviously) so it has 90% of the complexity build in but has more room for the video section, the major heat source to breath. The often claimed better sound quality than AVR are mostly generated by the powerful Placebo and bias, one of the biggest myth/scam ever created lol..., but it is so powerful that I would say most users might/could/would hear better sound quality, though still ymmv.
If you can live with the minimalistic video features, vs the Marantz AV10 and AV20, or the AV30, miniDSP's Tide 16 should give you the best available audio performance, I would say even better than the much more expensive Storm audio, even Trinnov. It's also less than half the price (when you factor in the Dirac Live licenses included with the Tide 16 of the AV10, but in the US you probably have to pay more because the dealer won't likely eat the Tariff.
