Sennheiser HD520 II (or HD530 II?), back when those were current models. Completely blew my mind.
HD5XX was the best I have heard. Second is the EPOS H6 Pro open back. But the best sound system has got to be the Bose system in the VE Series II Holden Caprice. Sharp, bass is very tight, and excellent imaging with its centre woofer, as well as front tweeters.
There are dedicated subs for audio which is more useful, but the truth is for the majority of PC use cases, any decent set of headphones is good enough. I have an ancient pair of Sennheiser HD5-- headphones that are still awesome. A monitor or any other PC part from that era is basically garbage today.

Sennheiser 500eries goes on sale or refurb often cheap. They lasted me about 15 years, hella comfy as they use a velvet cup instead of fake leather shite
I've listened to AC over the years on a few different sets of cans. The best experience in my opinion is a pair of open-back headphones. Specifically Sennheiser HD 5XX or 6XX. It allows the wide soundstage to really shine through the level of detail that is revealed is amazing.
