Opinions: Neuance Shelf for Linn Sondek Lp12 TT

Thank you all so far for a further enlightenment to my conundrum. To add to my explanation of the current condition. My living room set up has Coincident Total Eclipse speakers three feet off the short wall of a 15'by 26' space. My Atma-Sphere mono blocks are located next to the speakers on stands with a six meter interconnect to my preamp, phono amp, and TT. The TT and shelf is located on a short, non load bearing (?) wall adjacent to the speakers. It is next to my listening chairs about six feet from the back wall. The home is of 1926 vintage with beautiful but unstable hardwood floors. The walls are originally plaster lathe and have had an additional layer of sheet rock bonded to them. All in all the room sounds nice. Maybe this info will help in understanding my room better as some of the most helpful responses were predicated on some assumptions due to my less than compete explanation. Thanks again and I look forward to any new ideas.

If your table isn't bothered by foot traffic now and the woofers exhibit no pumping then my advice stands. Beyond that, the short wall that the rack is on may need supports from below if possible. You are probably far enough away from the back corner with the turntable location to avoid bass build up problems.

That'a a great response from Lugnut. Cleared up a few points for me, like the lower limit of the vibration control of my LP12's suspension. Thanks Pat!

Just to add my 2 cents... a wall shelf is one of the best ways to mount a suspended TT, IF the wall is an outside, structural, load-bearing wall. Such a wall is coupled directly to the ground. My LP12 is mounted like this and you can slam the front door ( a few feet away behind an interior wall ) without the turntable noticing it.

RF Sayles, you've made it clear that your TT shelf is not mounted on such a wall. Your short wall may be coupled to the floor in that case, and if the floor is at all bouncy then low-frequency, seismic-type vibrations are reaching your TT's suspension and it cannot deal with these effectively. Really, nothing much can that I know of, although the roller bearings others mention might be something to try.

In my experience, if the floor is at all bouncy, a heavy floor-mounted support is not a viable alternative to a properly set up wall shelf. I once worked in a first-floor store which demo'ed TTs ( yes, long ago ) on a low brick wall. Real brick, and quite deep. The thing looked solid, but if you walked by with a heavy tread you could see ( and feel ) the whole wall oscillate very slowly up and down, at maybe 1 or 2 Hz. Lugnut's suggestion of a support pillar under your short wall ( down in the basement, if you're listening on the first floor ) makes excellent sense. Channel the load on the shelf down to the ground and you've got a sink for vibration.

Or you could just move the TT shelf to an outside wall, thus necessitating a rethink of everything else in the room as well... not an option, perhaps!

Finally, Linn's Trampolin suspension is said by some to be useful if your TT support transmits vibration, but others say it does not help the sound. I have removed mine, and I run my LP12 on a Target wall unit with the standard shelf and Audio Technica feet.

Lugnut,

What a great post. You really stayed on point and gave great advice.

I understand exactly what you say about Linn detractors. I find the same thing with Krell products. I get tired of Krell bashers. I have tried many products, but find the Krell products that I have owned to produce the most musical sound (especially with my big B&W800's) that I have heard. I am using the sound that I get from listening to the SF Symphony where I sit 9th row center as my reference. During the last 18 years, I keep coming back to Krell. ... and the company is great to deal with.

Also, a note to R_f_sayles: My room is almost exactly the same size as yours and with my system, the sound is best with the speakers oriented along the long wall.

I use Neuance shelves under my Linn (on a rack) and under my CDP. I think it's a great product and an outstanding value.
