Why do audiophiles shun feedback in amplifiers?

NFB....love it or hate it.

Most things occur in shades of grey, not pure black and white.

Hi Kijanki - thanks for the link. I am going to have to ask one of my viola colleagues about this tomorrow! As far as I knew, the string lengths of all the instruments in the orchestra string family were approximately the same length (with the obvious exceptions of harp and piano), but that article claims this is not necessarily true of the viola. I am now wondering if this is a typically sloppy Wikipedia reference to viols, used in early music groups, which are of many different sizes, or if it does indeed apply to orchestral violas, which I tend to doubt. I will report back.

@Dracule - yes, audiophiles use quite a few terms somewhat differently than musicians do. My personal pet peeve is "neutral," LOL! But there are others, even such seemingly self-explanatory words as "mid-range." This is a very misleading term to a musician unfamiliar with how audiophiles use it, as it turns out that the vast majority of frequencies produced by acoustic instruments fall well within what most audiophiles call the midrange, though audiophiles will often disagree on exactly what constitutes the midrange. Other obvious candidates are "pace" and "timing." I have seen some very bizarre discussion of those two terms in particular on audiophile boards.

Learsfool, "neutral", in almost all cases, is a subjective audiophile term. IMO, only people truly qualified to use this term are recording engineers who have the capability to compare their recordings with the live performance that was recorded in their studios or venue. Don't get me wrong, as I've sinned too using this term in the subjective sense for lack of a better word.

As for "midrange", this can cover 200-300 Hz to 1-3 kHz depending on the audiophile. And yes as you state, this covers most of the frequency range of most instruments. That's why most audiophiles often proclaim the midrange is the most important because most of the music occurs in this range. Broad yes, but sometimes useful.

Learsfool, when you are not talking about orchestra musicians, the idea of long scale and short scale basses is well-known. A short-scale bass (electric, BTW) will have a neck about the same length as a guitar. A long-scale bass will have a longer neck, so the translation between the scale for a string bass player to a long-scale bass is about the same.

Long scale and short scale concepts are not used with classical instruments. But there *are* different sizes, at least with basses; I played a half-sized bass in jr. high, but my personal bass was a 3/4 size. As I understand it, full-size basses are rather rare- I don't think I have ever seen one. Most of the basses you see in orchestras are 3/4 size.
