Silky and soft highs: product of coloration?


Hi folks this is a bit controversial topic. I know some amplifiers (and some very expensive ones too!) have a very silky and soft presentation of the (upper) treble. I'm wondering if this silky presentation can be considered as a hallmark of quality for amplifiers or rather a sort of coloration that makes the upper treble soft and "pretty". In my opinion I can divide amplifiers in two groups: one group (the largest) with "ordinary" treble response (not very pretty) and the other group that consists of only a handful of amplifiers (both solid state and tube) with a refined and silky treble. The contenders within this last group are alas too expensive for mere mortals. This brings me to another question: is such a refined and silky treble only to be had with megabuck amplifiers?
I consider the Anne-Sophie Mutter recording "Carmen Fantasie" as the ultimate test recording for treble sweetness. If the amplifier sounds just "ordinary" with this recording (especially where the violin plays in the upper register) then the amplifier is not "refined" enough.

I agree in general, BUT this must be done very carefully. First, you must realize that the recording chain is every bit as sensitive as the playback chain. Also realize that almost all mics add coloration.

Ok, so you've got the most incredible recording chain possible and a virtuoso comes to your house and stands between your speakers and plays as you record, but don't amplify. When you play back the image can't possibly match the point-source of the actual instrument. So, it's best to play the feed through the speakers so that you'll hear the same perspective on playback, unfortunately that adds the coloration of the playback system to what you hear.

IME it's best to let the musician play without going through the speakers and then focus almost entirely on timbre on playback. This is still tough because of mic proximity effects and the coloration of the recording chain, particularly the mics. Placement of the mics is tough also.

So, this is MUCH easier said than done.

Hearing live acoustic instruments often, from a variety of perspectives is as good or better, IMHO. The real vs. Memorex thing can be pulled off, but it's not casually done.

Regarding importance of amplifiers, it is important to match amp specs to speakers correctly and set the speakers up properly in the room. After that, it is mostly personal taste that comes into play, IMHO.

Spending more on an amp assuming better sound is definitely not a guaranteed win.

Regarding the highs, once amp is matched properly, I think you will find a wide range of discrepency regarding high end quality that results from a combination of source unit design/quality, recording quality, matching of proper interconnects, and quality of power supplied.
