This is a tough one for me, I used to work next to an amazing audiophile level stereo shop that catered to the wealthy of SoCal. If I remember correctly I think they had 6 or 7 listening rooms and an theatre room with an amazing projector/SS setup. I don’t know if I could say I listened to 125 different systems but definitely that many variations and most were worth far more than 50k. I think I was lucky enough to be well thought of by their employees and due to my respectfulness, reading and taste in music I got to listen to stuff I will likely never be able to afford. I think I was also lucky in that they knew where I worked and that I couldn’t even afford their least expensive rig so I would get left in the room with some records and 200k worth of gear to simply listen my lunch breaks away. It taught me a lot and even though I cannot afford that grade of gear it very much cemented that it’s worth it if you can afford it. Those were good times.
