I tried fast response at 3' away with the meter playing differance records. I get up to 99db spikes. At 9' away its up to 90db. At the 12:00 position.
Someone told me Im getting feed back. My turntable is only 2' behind and to the right of my right speaker. Was told to place all my source equipment across the room. I posted this question on Cable forum. Ill keep trying those other things you mentioned. Checking into it. Thank you most kindly for your help. :)

For sure try again with a CD player. Even better if you find one with variable outputs and bypass preamp completely. I am pretty sure problem is related to turntable picking up vibrations from speakers and/or record wrap. Do you know beyond a doubt that the suspension is set up properly on your Linn? I would suspect that big time. Is it possible your cartridge suspension is worn out or a poor match for your table/arm? I know Grado's don't get along with my Thorens and the problem is much worse if the tables suspension isn't perfect-which btw is a big pain to adjust.Russ
My LP12 was adjusted by my local dealer and even had a few springs replaced. Im in dire need of a Circus upgrade. My springs creak when i do the bounce test. Also the cart im using isnt even made anymore. 1995. I know i need to throw money into the Linn. Ill do that CD test next. Thanks for the help
Glad to help in anyway I can. I have been going through the same stuff with a recently acquired Thorens table and your post sounded so familiar I had to comment. Careful adjusting of the springs and a new cartridge made all the difference in the world. In addition to the bounce test makes sure it moves side to side freely too. For what it is worth I was using a Grado and switched to an Audio Technia 440ML. Not quite as warm but at $99 bucks for a micro line stylus the price was right. Tracks great and no low frequency rumble when I crank it up. Classic rock demands volume at times....like when the lady of the house ain't around...lol. Keep on spinning cuz vinyl is dead.Take care,
RussPS Try a wall mounted shelf. Think low mass and ridgid.
Do you have a cd player or have you tried one as a source yet? That will answer the feedback issue real quick. Even if you have to use a walkman type player with an adapter cord.And on the turntable front - of course there is also the subsonic question. If the Grado / arm combo are incompatible you could be using all the power putting out subsonic info. Do you see lots of random woofer pumping - I mean big visible excursions for which you dont hear a corresponding sound? This is also a frequency region where the Rat Shack meter is notoriously unreliable so it could be missing it...
