Cartridge rings at certain high frequencies


Hi all, I am new to the forum, and this is my first post. First my system, mainly vinyl based and consists of Linn active Amps & Speakers, with a Michell Gyro modified with the Orb platter, plus an SME 309 arm. Phono pre amp is a Graham Slee reflex C, cables are Nordost. Cartridges are various, but exist on all of them, currently an AT33EV MC.
On certain high frequencies I get a ringing sound, a sort of harmonic, but not truly a harmonic sound. It's not on all albums I play, such as all my 180gm, but shows up on a lot of the 120-140 general vinyl. So far I have tried the following. Checked the arm and cart every setting at least fifty times, so much so I can now set the Azimuth blindfolded and asleep. I thought it was my music room, so in went the rugs, carpets, cushion, sound defuses, traps etc. didn't make any difference, it was still there. The TT does have DensoDamp fitted and the SME doesn't ring at all. The only thing that hasn't been changed is the cable......so I have bought a lot of Linn cable to try, but first thought some of you kind people may hopefully tell me of something that I have missed.
I do have a DS player, not that is used a lot as vinyl is my prime listening pleasure, and I occasionally get the slight ringing, but not as prevalent as with my vinyl setup. Thank for reading and thank you for any assistance that you can provide.

Could be the acoustic energy that flies around the room when you are playing the TT. Few people tame this large source of energy as it hits the TT, cartridge and all the components. Put the TT in another room, away from the speakers and see what result you get.
It sounds like something is loose or ringing somewhere since it happens when the speakers reach a certain frequency or energy. Could the tweeters or speakers need to be torqued down?
If your system "rings" on other sources than the phono the problem is elsewhere. Is any of your equipment tubes? Tubes by nature are microphonic and will sometimes have a type of ringing.
Hi, thanks for the reply, I did move the pre amp out of the loop and used the DS direct into the power amps, and it was still there, I just wonder if the cable could cause this ringing sound? Not that I know much about cable, except that originally it all sounded great, thank you for the reply

Thanks for the reply, I have put a lot of sound damping stuff into the room and even studio acoustic tiles, but never made any difference. But, I will re visit this and try again, thanks for posting
