Tower speakers properly positioned (to get the ‘wall of sound’ sound stage)

Stylus/cartridge (that tends to sound warm) + turntable + vinyl

Tube amp? (+/-)

Drugs

Golden ear Triton 1 R blew me away. I don’t have enough space for them without the woofer reflecting off a cabinet or they would be a no brainer

If it was over heating it would most likely turn off after a thermal threshold was triggered. Looks fine, amps get warm.
