I have infinity Primus P362 towers with old Technics SA-GX 490 AVR 5 channels but no sub, Sony mismatched center, and a couple of small surround speakers. This is ok as a stereo but not great. I would like to stay with a small print but a large sound system. My budget is up to $2000 ( can stretch to $2500 if necessary). I will be listening mostly to Spotify, Pandora, YouTube, and Amazone prime music.
