Thanks JohnnyB for the clarification or your setup. I need to work on my stack.

Since this is about the SL1200 I thought this might be related enough..... I've decided to move my 1210 TT to a more permanent place. Though not the final place, that will be an audio rack in the distant future. As a part of the relocation of the TT on my table that holds my amp center speaker and TV, I wanted to try out the racquet ball feet approach. I purchased racquetballs after reading about their ability to reduce vibrations transferred to the TT. I know about spiked metal feet, isonodes, Isonoe Footers as replacements for the stock feet. I wonder about the nicely make isonoe feet but they are $180. My 1210 has a KAB fluid trough, and I use a isoplatmat and herbies mat under the LP. I am finding that the racquetballs are better than the stock technics feet for reducing ambiant vibrations. I tested these variations: (1) TT on Racquet balls resting on rack shelf (2) TT on Racquet balls on cutboard which was resting on rack shelf (3) TT on stock feet on cutboard resting on rack shelf (4) TT on stock feet on cutboard with Racquetballs under resting on rack shelf What I am calling a Rack shelf is an ikea coffee table similar to LACK construction. The way I determined the amount of vibration being transferred was to observe the speaker driver while stepping, tapping, and hand pounding on the shelf and hardwood floor. Setup #4 was by far the worst as the. There was hardly any difference between #2 and #3. With #1 I could hit my closed hand down hard inches from the TT and the woofer barely moved and there was no associated sound same for heavy footsteps less than a foot away. BTW no music was playing but the stylus was resting on an LP and the volume was increased slowly to get to normal listening level. I think the raquetballs look very clugey, but they work. Not bad for less than $10 for 6 balls. Leveling maybe off a degree or so but that is what is great about the 1210. I just ordered a bubble level. Another day while listening to music I decided to make a video to show the abuse I gave the set up. Video 1: the pound/tap test: http://www.vimeo.com/3427722 Video 2: the door shut/stomp test: http://www.vimeo.com/3427932 I ultimately may end up with a sandbox but want to design my own, though not build it. Brass feet may work in that set up. I will watch this thread for others experiences with them. My current TT setup still sounds great to me. It's very dynamic and the noise floor is extremely low to me-which is was on the stock feet and butcher block. Now, with the rubber balls, it can just handle having a bunch of people around while it is playing-I have hardwood floors. cheers, ed |
Hey Tvad, are you the one who got an AT150MLX cartridge and got rid of it because it revealed too much surface noise (or was that Viridian)? I did a little platforming tweak to my SL1210 that dropped the surface noise like a stone. Basically, put threaded cones on the SL12x0, get some floorsavers at least 1-5/8" in diameter, and place these on a set of #2 Vibrapods. Situate the cone points on the floorsavers on the Vibrapods. Place that on a platform (I use a butcher block cutting board) and pad the cutting board with a couple of 19" gel wristpads made for computer keyboards. Or you could use another set of Vibrapods under the cutting board. |
