A noble effort, and probably essentially correct.
I installed those 1K resistors in my monoblocks from the get-go (~8 years ago) and so have no experience of what they would sound like without them. But there is absolutely no treble peak in the output of the amps, driving my Sound Lab M1 speakers thru a pair of Zeros. I never thought to mess around with that resistor, but one wonders what might happen if one changes the value to say 100R or 10K ohms, etc etc. Obviously that would alter the amount of feedback but we don't now what THAT would do to the sound. My amps, what with the MA2 chassis' and transformers that they use, are so heavy I am loathe to perform experiments of this type, especially when I am quite happy with what I've got.

My acoustat III OR X, An my Martin logan SL3,ROLE TOP DOWN A TUCH!Not peaky,B&w 802m 804m 805n show the peak.An yes lower r500 not r1k well tighen it up more,I am r 800.Bypass caps .86uf500v bypassed 16uf250v SILKY, THE BEST SOUND YEAT!Thanks T.V.
So, you are now using a 500R resistor bypassed by a 16uF capacitor in parallel with an 0.86uF capacitor, for a total of 16.86uF of capacitance. Is that correct? Once again, I would ask how you calculated the amount of capacitance that would be best or if you are just doing this by trial and error (which is perfectly OK, too). To my ears, many of the B&W speakers of the past had a fairly peaky sounding tweeter, with some amplifiers in some rooms, etc. Maybe that is what you are dialing out with your bypass caps.
Yes B&W Do have that peak on top, To my ears all but esl have a puch up at top, I do love my ESL,S. But in tampa fla some time do not work so well. But caps sound same ON esl,s! As for cap uf. By ear. thanks T.V.
