I'm not an audiophile and certainly a newbie at this so wanted your expert opinion. I'm thinking of buying an AVR around $1000. Main goal is to run a 5.1 home theatre and a separate zone for another TV and stereo speakers. Looking for 4K support. Should I go with an AVR or should I look for separate components like an amp and receiver? Seems like there's alway new stuff coming out. Thinking that an amp is an amp. If I want to upgrade to a 7.2 setup or add another zone, it would be better to go with separate unit rather than an integrated AVR. Can you please recommend options? Thank you!
