[Soundside]

Yes, it’s mounted vertically with a slight tilt backwards.

I’m not really concearned about the sound, I’m thinking more of the life of the amp, bit it should do anything to the ingernals right?. Some ”audiophiöes” swears by blocks of stone, cones or dampening feets under their amps. Just thought I’d ask regarding my not so rigid stand
