Yes.

Also I find few recordings so bad they are not listenable. In fact, when things are going well on my system, I find most tracks to have something appealing enough to offer to make it worth a listen. When not, then I find myself discounting a lot of recordings that in fact should be quite enjoyable if not still far from perfect.

You had your s500 modified , Yes?

In the past , I have found the threshold pre-amp combo very sensitive to the cables/CD player output impedance/ cable type combo. Playing around with the cable from the CD player to the FET/10 makes a huge difference in perceived harshness picked up in the upper midrange area.

This has been my experience over the years and Currently I can play any type of recordings or Music, my only concern is popping the 15 amp fuses in the amplifiers on really loud crescendos....

I agree. I suspect this may be the most useful metric regarding system quality of all.

I think we might be having a linguistic challenge. I don't consider hardness and harshness to be synonymous. For the record I have not complained about harshness from my system. On rare occasion I detect a bit of hardness. I am confident that this is recording dependent.
