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.

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.
i use HD 5xx, i have owned HD580, HD598, EPOS/ Sennheiser Game Zero. for amps i use Asus Xonar Essence STX, and have also played with Schiit stuff. Id like to get an HD 650 but im very happy where i am at. so for me its 150$ HD 5xx and a half decent headphone amp for another 150$ or so. It really depends on what your 'hobby' budget is.
