Less fatiquing

I would SERIOUSLY look at your other components before giving up on the Brystons. I don't have much experience with PSBs, but I've heard a few people accuse various models of being a little hot on top. Your digital components might also be likely culprits. Others with more experience with the particular gear in question will have better advice, but I used to own a bunch of Bryston gear, and when properly mated with appropriate partnering gear, I never found it bright at all. Methinks your problem is elsewhere.

I had a system that was too aggressive and harsh in the midrange. Putting in Cardas neutral reference cables did the trick for me. It really took the aggressiveness out of the mids. I no longer have that system, and am currently selling the cables here on the 'gon. It's not exactly a "cheap" fix - still costs a bit over $500.

If you have audio friends, I would suggest that you try substituting in pieces of their equipment to check out various links on the chain.

I would like to throw the room into the mix too. Speaker placement can sometimes correct deficiencies but a room that is hard will take some work to warm up. Some experimentation with the room can usually yield good results.

I use cables like tone controls, as do many other folks & don't forget PC's & receptacles when looking into cables.

I agree with Hooper. The amps may be playing a role in this, but it is more likely your source or speakers. Consider upgrading to a Transport/DAC or computer/DAC, which is superior. Mods to these can further minimize sibilance. Some sibilance will be caused by jitter in the digital signal.
