B&W 804s too bright


Hi all, I have just purchased a used pair of 804s in good condition. But the thing is, I find that they actually sounded a bit too bright. Before this I was using a pair of Martin Logans and had no such problem. I was thinking whether it is my other equipment which is giving me the problem.

I am running the 804s with Emotiva XPA-3 power amp, ERC-1 CDP and Marantz 6003 as preamp. In between pre and power I have a Yaqin tube buffer to add a tinge of tube taste to all.

Any suggestions?

I've read many posts here and elsewhere that mention B&W speakers being very bright. In contrast the Martin Logan are frequently characterized as having smooth, non-fatiguing treble.
Sell the B&W's and get warmer speakers or keep the B&W's and get warmer electronics and cables.
most likely i will not sell the B&W.. sold my martin logan and bought B&W because i need smaller speakers.. any recommendations for warmer electronics and cables?

I am using Chord Carnival Silver Screen bi-wire now btw..
