Wait. Why has no one discussed how a (vacuum) tube amp falls in a vacuum? 🤔 Would certainly be as relevant as weight to an amp’s performance...
One must first decide what class. Older tech (A, A/B) Is going to weigh geometrically/exponentially more than new tech (D,G,H, Hybrid) by necessity. Anyone who has not auditioned the newest new tech (Ice, Hypex, Hybrid) should not dismiss them based upon “old” new tech class D. They offer very good/great performance, can handle difficult loads with ease and dynamic headroom, and come in an efficient package that can be moved around and placed in tight racks/spaces without hernia or fire risk. Oh, and have correspondingly exponentially greater SAF
Sort of Indycar/Formula1 compared to Hummer/Escalade
