Listener fatigue is very real but can be more on the subconscious level.
But beware of both sides of the coin.
There's a fine line between amps that provide so much detail leading to an overly bright sound and amps that veil, smear, and roll off the highs and sometimes dynamics so that you end up listening to Musak elevator music.
Especially beware, when people say "I could listen to this amp for days or forever."
As Peter Moncrief of IAR said regarding some of these supposedly hi-end and very expensive and popular amps, "These amps may be easy to live with. But it's the other amps you won't want to live without."
Also, I understand that the Thiel line can be a more bright speaker than the average.
You must match components carefully for so that the sum is greater than it's parts so to speak.
For me, music can be very dynamic and yes even to the point of fatigue if loud enough or played long enough.
I want my components to capture that 'live' bite if it exists in the recording. It can always be toned down in different ways, but I certainly don't want some high priced electrical engineering amp wiz making that decision for me.
-IMO
