I probably have more than that in audio hardware and software for recording and stuff in the office with my computer.
Yeah most of my gear is vintage so it's not that expensive
the most expensive piece of equipment I have cost me about $500 and that's only because it's hyper rare and absolutely mint so the seller milked me for as much as he could
here's a list for those who are interested
ObjectiveDAC
Matrix M-Stage
Sony DR-Z7
Pioneer Monitor 10-II
mm I also have two sieveking omega headphone stands and an open pandora rebirth for a portable player but I wouldnt really say those count as audio gear
