Thanks for your response. The front L/R speakers are Infinity Kappa 5.1 Series II. The center is Infinity CC-3. Rear is Infinity Reference 2000.2. Sub is Velodyn VA 1210.
I have a 4k TV, and most of my content is streamed. I'm not too picky, but would really like to have modern connections as well as good sound. I'm looking at $500, max. My current receiver does not hook up directly to my tv, so I have to use a converter box, which can cause the sound quality to become distorted at higher levels. This only happens with streaming. My wife is annoyed by this distortion, and she is not picky with sound. It's mainly the lack of ability to connect my TV to my amplifier, legitimately, being the reason for this upgrade.
