Car mostly now. 2.5” Pioneer dash speakers, 6.5” Polks and 6.5” Kenwoods, 10” Pioneer sub and monoblock amp. About a million times better than any upgraded audio system in a new car. Crystal clear audio, very tight controlled bass. It’s sublime.

Otherwise in the house from Apple Music Lossless through the Sonos Arc+sub gen 3+ surrounds and HomePod minis, very rarely through the home theater Atmos syste (Yamaha TSR-700 and Onkyo fronts and sub, and Niles in ceiling surrounds).

I’m a firm believer in not wasting money on expensive amps and gear for marginal gains (pardon the pun). I went to school for audio engineering and have mixed on $100K speakers. They sounded phenomenal but I have more fun in my car with its ~$600 system than anywhere else. Audio is very psychoacoustic. When you’re groovin’ the system almost doesn’t matter.
