It is better to have two separate systems for 2 channel audio and HT.
I had a $3K Yamaha receiver (one of their flagships over 20 years ago) that sound much better on movies (with DVDs and Blue-Ray disc) than my 2 channel systems. My Yamaha sounds much worse than a $500 Chinese tube integrated amp for 2 channel music.
Also, my Klipsh KLF20 (a HT speaker with KLF7, ...) sound much better on movies than my other much more expensive stereo speakers. However, it sounds much worse on stereo music compared to my other more expensive stereo speakers.
It will be tough to have one system to serve both purposes. I had tried with my Klipsch speakers and a few HT receivers, but 2 channel music just did not sound right, and moved on to two separate systems since then.
