So how is it possible that there are speakers that are detailed, very good quality and still forgiving to "bad" recordings?
Low distortion.
If you over sharpen a digital photo, you'll see more detail. But in fact you're losing the information. If you want a truely more detailed photo, you need a better lens and sensor, not a bad lens, noisy sensor and Photoshop.
With an "over sharpened" musical presentation, the brain compensates for this, but over time the effect is fatiguing and makes you turn off the hi fi.
It's not just the speakers, you need a good "lens and sensor" as well i.e. a complete system that preserves the original detail on the recording without introducing unnecessary spurie or "enhancements" to make a piece of kit sound impressive. Which is where IMO, some kit falls down and leads to the seemingly widespread observation that better hifi kit often murders a poor recording.
Just my 10p
