mainly because I also plan to see how well they will drive my headphone that I listen to quite a bit.
If headphones are important, at this level I’d get a separate headphone amp as the ones included in integrateds — even the better ones — are relative afterthoughts and not anything special at best (amps matter for headphones too!). When you can get a nice fully-balanced, Class-A headphone amp like the Singxer SA-1 for only $599 that’ll kick the crap out of any integrated’s headphone section, I can’t see using an integrated’s headphone section if you’re truly serious about headphone listening — and the SA-1 is small so not much of a space penalty for the level of benefit you’ll get. Just my $0.02 FWIW.
