Combining home theater with two channel

Do NOT combine unless marginal results please you.

@bkeske summed it up nicely.  I have the Marantz AV7705 that I use for HT.  I have a Herron VTSP-360 Reference preamp that has home theater bypass feature.  My amps for the front two speakers are Herron M1 monoblocks (150 WPC).  While these amps aren't pushing a lot of watts, they have huge transformers and can deliver a lot of current.

I am not one to say Emotiva is junk (I have an XPA-5 in my bedroom system), but the quality of the watts matters more than how many there are.  Your speakers appear to be fairly efficient.  You shouldn't need a huge amount of power for them.

A good integrated will have a much cleaner preamp and amp than the Emotiva/Marantz combo.

Think of music this way... it's ALL there, but when you have inferior components you're only letting part of it through.  The better your components, the closer you get to what's really there in the music. 

I am not "critically listening" when I'm watching a movie and I want the surround sound experience provided by the Marantz, but when I'm listening to two-channel music, I want as little as possible coming between me and the music. 

If I had the space, I'd have a dedicated system for music and another for home theater, but an integrated or pre-amp/amp setup with HTBP is a good compromise.

My dealer suggested that I add an integrated amp to the system to play music.

BINGO! Your dealer nailed it (along with everyone above). The cheapest option to dramatically improve your 2-channel performance is to incorporate a good stereo integrated (w/HT Bypass if possible but not absolutely necessary, which opens up more possibilities).

I'd try to work with your dealer to demo a good integrated — that being one that has the same characteristics you’re looking to improve upon — and see how that goes. Your speakers are revealing enough that I think you’ll hear quite a big improvement, and if they’re the model I think you have 150Wpc may well be plenty. Anyway, best of luck in your quest.

OP might look for a high quality used processor to use with his amp rather than an integrated.  I use a pricy Bryston SP3, but I think a Cary Cinema 12 would be fine.  My setup is similar to that described by bkeske.  The SP3 sends balanced front LR analog to an Ayre KX-5 Twenty preamp bypass and center channel directly to a Parasound JC 1 amp.  A good processor direct to his amp should be fine for stereo and HT without a separate preamp. 

i have a marantz 7011 for home theatre running into a vitus intergrated with home theatre bypass. i use an ayon s10 sig streamer dac into the vitus for music.

its the best way for both worlds. i believe the vitus also helps with its pre for hometheatre. i dont use a centre as my two fronts are good enough. wilson benesch precision p3.0.
