A revealing HiFi system brings out everything great as well as the opposite.

You've invested in a genuinely revealing system and now you're worried it's going to make your favorite recordings unlistenable.

I hear this most often from people who love older recordings — opera from the 1950s, jazz classics, Mahler recorded before multitrack was standard. 

It's true that a revealing speaker shows you what's in the recording — the technical compromises and the music both. And for recordings that have real music in them, those aren't in competition with each other. A Miles Davis session from 1957 on a great system sounds like exactly what it is: musicians of extraordinary talent, captured on equipment of that era, in a room with its own character.

The hiss is there. The limited frequency extension is there. But so is everything that makes the music matter — the phrasing, the dynamics, the presence of people playing for keeps.

A great recording made in 1958 is still a great recording and the best systems don't magnify flaws, they embrace them as part of the act.

The equipment just helps you hear more of the good stuff.
