Being bright is only one aspect of listener fatigue. If the treble control cannot tame it, there is probably an annoying upper midrange resonance present. This would be a peak in the frequency spectrum caused by poor isolation of the internal components such as the transformer or filter caps. Your original components are high quality and their construction takes this into account.
Listener fatigue
What causes it and what brands caused it for you?
I have been using a ML No. 383 with Meridian 508.24 for a year now and the one thing I always liked was I never experienced listerner fatigue. I was recently experimenting and hooked up a McIntosh C42 preamp to a Heath amp (cheap, it's all I could get my hands on). This amp is very bright, but I heard some things in the combo I liked, but I cannot listen to it for more than a few songs without it giving me a headache, even with the treble turned down (the Mac has an 8 band eq.).
Is this generally due to a bright sounding system or are there other factors that can also give this result?
