cables.... not a big believer, so Anti-Cable or Blue Jeans would be about the most Id spend to get good terminations and affordable cables.
Sub..... Id go Internet Direct brands for better bang for the buck, Hsu, SVS, Rhythmik, Seaton, Funk.
i think that if youre just movies then a good pre-pro would be Marantz AV7005 or Integra 80.3(models may have been recenly updated)
I like the Parasound Classic multi-ch amps personally. Never heard an Emotiva but they get good personal reviews, Outlaw audio has good multi-ch amps also.
For 2-ch I use a Naim Nait 5i integrated amp with its HT bypass(the integrated acts as a power amp when watching movies and the processor is turned off) so that I dont run music thru the Integra I have. I find the Naim has better dynamics and is more detailed and has better sense of musicial flow then the Integra that can sound warmish, but a little lack luster for music. You can be the judge if you feel you need a dedicated 2-ch pre-amp/integrated amp for your needs musically. If youre going to include it as part of your HT system, look for units that have a HT bypass or unity gain. Focal and Naim are owned by the same company, so they should sound pretty good together. But theres lots of other choices.
If you want a DAC I use an Arcam rDAC and like it a lot, the PeachTree DAC*iT is supposedly pretty good for the price as well. There is always the Oppo 105 that looks like it can be used as an external dac now too. I have a sony blu-ray player and I output via optical my cds to the rDAC, the sonys analog section is not very good. If not for the dac then I would get an oppo and use its dac. Choices choices.
