Maybe, but could work I think. I would say though that rather than buying and setting up a system to deal with harsh recordings, the alternative option when faced with a 'harsh' sounding recording, would be to turn the treble down a notch or two, simple! An even simper approach would be to note that the particular CD, album or whatever is a little harsh in the treble, ignore it and enjoy the music for what it is.
I think it's not the magnitude of treble that we all complain about. I bet the frequency response of these recordings isn't out of level if you meassure it.
It is all about jitter - a time dependent distortion if you will, that our ears are not capable of to compensate on. It's an unnatural distortion.
Some CDs carry a lot of jitter in its recording (due to bad digital recording or bad A/D processing). You can not change that. Jitter patterns add up during reading/streaming/amplifying (D-Amp) and you would get more and more of these 'Out of Phase Signal Patterns'. One brain earlier like the other complains about the harsh sound of treble. This harsh sound is only an 'Out of Phase Signals' and as we are very sensible in the highs we recognize it easier in this frequency band.
I know this because when the source is getting more precise, jitter (edit: jitter of the audio chain in sum) lessens and the harshness goes away...it gets In Phase to the rest of the music signal and contributes to further transparency and 3D-Mapping.
Get better power, source quality and cables and everything will be ok.
Lowering the treble is like the pill from your doctor who doesn't know what caused your illness.
