I don't skype but my .02:
Integrated 2ch amps are generally more expensive than an equivalent avr as they're made in much smaller numbers...economies of scale. Nothing wrong with an avr's amp section as long as it meets your spl and impedance needs. Your speakers are 90dB sensitive and rated as 8ohm compatible so doubt you'll have much issue with an avr's amp (plus you have the built in "subs" with their own amp to further take the load off the rest of the speaker). 2ch integrated amps generally don't provide any bass management for use of a separate subwoofer (which you may or may not want, you don't say), or hdmi connections or networking capabilities. In 2ch use an avr's power supply should be fine, many do complain that when all channels are driven equally (which isn't a normal circumstance) that the 2ch driven ratings change. Not a big deal.
Buying boutique stuff like external DACs wouldn't be necessary with an avr, and most avrs have good networking capabilities where you can use something better than bluetooth (like streaming via airplay or dlna). Most DACs are quite competent in today's audio gear....phones not always (but they're phones...).
NAD is okay as long as you don't mind paying more and getting less features than other major manufacturers; that they have some inherent superior sound quality is often touted but something that isn't borne out by many user comments I've read, YMMV. NAD and other boutique gear is more expensive as they don't have the sales/distribution the major brands have...still made in the same general factories in China.
I use avrs in my setups that I use the most, as I do like the ability to use subwoofers with bass management as well as the networking and surround sound capabilities. I'd want real subs with your speakers, but you may be happy with their built-in "subs" despite lack of ability to place the subs separately from the speakers, which is generally ideal; I also like mine to dig deeper than the Tritons can for a wide variety of material but YMMV. My 2ch gear is in the spare bedrooms for occasional use.
Acuras do use Honda engines, everything Acura has is Honda since that's the parent company
