Fatigue Subjective???


I went to my local high end store and compared to Thiel CS 1.6 played on a Naim system to the CS 1.6 on a Levinson/arcam system. The naim system blew the Levinson away in sounstage width and depth, continuity of image, musical involvment. Only bad thing about the Naim was the fatigue, which was immediate.

So I called up the dealer,today, thinking maybe there was one weak link in the Naim system, that if eliminated, would still preserve the good things but get rid of the fatiguing
quality. And maybe I'd get the Naim. The dealer (who was on the surly side and has therefore probably lost my business) tells me that since "fatigue is subjective" there's nothing that makes the Naim more fatiguing than the levinson, other than my ears.

My question: is fatigue subjective, or do some sytems/components produce it.

Hi Robert and all:

I think "fatigue" is used in many different ways. Some may be subjective. One example for a speaker is aluminum dome tweeters, which are often said to cause fatigue. Some are not very well implimented and a peek at certain frequencies after an hour or so of listening is about as subjective as a kick in the head if you ask me.

This does not mean that all aluminum tweeters are poor. Some, however, could be said to cause fatigue.

TWL: Do those Lowthers still sound so good after a couple days? No fatigue setting in?
I'll try to describe the "fatigue" more, and I probably won't do a very good job. Almost immediately with the NAIM system, I wanted to turn it down, and turn it off. It had something in the treble, I would guess, that was very uncomfortable to my ears. I get this from my factory car stereo sometimes, especially if I'm listening to CD patched through the headphone jack of my discman - and in the car it's not a high res situation. I play the thiels with a mccormack amp, and SS ARC preamp, and I have to stop and reset my ears. If I use the mccormack and a passive control unit, it's much more bearable. If I use a golden tube power amp, I can use the ARC SS preamp with no problem. So, I feel there are alot of factors - preamp, power amp and the source (digital). Maybe it's just the digital thing - I've heard many converters produce some nasty odd order harmonic distortion. The levinson setup did not make me want to turn it down, but it did not have alot of the spatial info the Naim setup had. If it's a software issue, one problem is that alot of good music is not that well recorded, so I don't want to paint myself into a corner with just a few listenable CD's.

I thank you all for your comments.

Listener fatigue is sujective and very real. I'll tell you a little secret, I find it often happens sooner at live musice performances than on good "systems". I find many live performances unnecessiarily and/or over ampilified. Sean is right on about how sound quailty seems to vary with ac and time of the day. As I've previously posted, I used to live in an apartment in New York that was across the streeet from a high school computer lab. With in hours of the school's closing, the sound of my system would improve. Upon the school's reopening the grundge would return. The Thiels aside from the low impedance, usually provide an easy load for amplifiers. I don't believe them to be bright, just not rolled off, as such they will show up componenet colorizations quite easily. You seem to have identified these coloriztions quickly. That's probably a very good thing. As there is no such thing as a completely neutral componenet, one has to find ones that have a balance that works for you. May I suggest you try the Thiels with Pass, Krell or the high current Conrad-Johnson (2300 or 2500 series) amps. There are other's that come to mind but I have not heared them with the Thiels, so I'm hestitant to recommend them. Good luck.
Based on personal experience, the Thiels sound good with the Rowlands and the BAT amps, also.
