A lot of people combine the two using the HT pass-through when they want to go the purist 2-channel route. If you use a projection system instead of putting a big TV between the speakers then the imaging shouldn't be compromised.
Other folks have used Home Theater and transitioned to multi-channel surround sound, although I can't say I've heard any of those sound quite as pure as an excellent, dialed-in, 2-channel system. I allow that multi-channel systems with naturalness and transparency might exist, but I haven't heard one at this juncture. (When I use words like "naturalness," and "transparency," realize there are many levels to such adjectives and it's a matter of which particular levels (or degrees of those qualities) one has personally experienced.)
