Help-sibilance!


Auditioning some Newform 645's which I love. However, as they have broken in, I have begun to notice quite a bit of sibilance which is driving me crazy. It is especially bad with my digital cable, but I first noticed it on Lyle Lovett's new CD which is a great recording. Any comments on what is causing the problem and potential cures would be most appreciated. System: Rotel 991, Rogue 66, MSB Link DAC, Newform R645's and Maggie 1.6's. Thanks, Mike

no, i don't have newforms - i'm holding out for a custom pair w/accuton midwoofs replacing the scan-speak revelator midwoofs - these ceramic drivers are even *faster* than the scan-speaks, & i tink they'll mate that much better w/the newforms' electrostatic tweeter.

regarding sibilance, i also find it to be recording-dependent, but i definitely agree that it can get worse as a systems' resolution increases - especially a speakers' resolution. i also think it's partially a product of digital sound. my analog set-up seems less-afflicted... prior to getting a tubed preamp, i had to run my cd-player thru a z-man ase, in order to be able to even listen to digital. but, w/the rogue 66 pre, i'm surprised there isn't the same synergy i found.

perhaps timvis is right - too much negative feedback on yer amp - perhaps the mfr can tell ya how much (if any) there is in the design. my electrocompaniet amps don't seem to have this problem... :>) rotel lists a 991 amp *and* a 991 cd-player - which unit is yours, zenaudio, & what's the other piece?

perhaps also sfar is right, & this recording is particularly bad in this respect. i don't have this specific recording, but i should get it & see - i have just about all lyle lovetts' other albums, & i've seen him live several times, so it would be interesting to hear - i don't think lyle has a sibilance problem normally... i think he has one of the best voices around, ackshully, and great lyrics to boot! ;~)
