Chord makes some of the best solid state gear I have ever heard. (I am not a Chord dealer)
Your point about Chord is a good one - I have recommended these amps in other threads. I am glad to see you finally came up with what I would say is a fair statement - it took you a long time though!
Are we sure that studio use active speaker for sound quality reasons? Maybe it's for convenience or something else.
Well you can read on line what people say about active speakers - Telarc Here is an excerpt: "We feel like we're finally hearing the detail of our work for the first time," says Telarc president Bob Woods of the installed ATC monitor system. "As a professional studio product we've never encountered anything quite like it. You want something that's accurate, but to have a system that can handle all types of musical programming equally well is downright remarkable. We do as much popular music these days as we do classical and jazz, especially through our new label partner, Heads Up. The ATC system handles it all without flinching."
You are correct in assuming that studios have a different goal in mind with active speakers - obviously they don't buy the "sound" - they actually by "no sound" - basically the goal is to have a system that does not impose any coloration on the recording at all. So many of the things you mention are important. They must not "compress" the sound at extremely high volumes, they must be precisely linear at all volume levels (no limited sweetspot in volume level where the drivers integrate their best), and they must be extremely reliable. However, your idea that studios want a colored sound with greater prescience or other gimmicks added to the playback chain could not be further from the mark.
