But surely new technology must sound better?

Ah yes, now THIS old chestnut! What new technology is that, exactly? Modern analog gear uses the same classic circuits, but often with lower quality parts and construction.

There is very little ‘new technology’ in analog audio. Most analog electronic circuits and circuit topologies date back to the earliest days of tubes and transistors. Even things like class-D and class-T amps are not new.

All the best tubes have already been made, as have many of the great transistors. There are some amazing integrated circuits now, for sure, but this new technology thing is grossly overstated and misunderstood. Digital is different and things have certainly improved, so newer DACs often sound better. I’m not saying there’s no great-sounding new gear out there, but boy do you have to pay for it.
