vinyl needs support...

Posted on March 31, 1999 at 21:47:00



What is your turntable sitting on? Turning table?

Mine is on top of generic equipment rack.
Apollo Adagio, 4 shelves, tweaked a bit.

Neither tt, nor stand on picture below isn't mine :-(

regards, gnat

Mine is on top of a siemic sink, which is on an amp stand that is spiked to the cement floor.

mine sits on a wall mounted shelf ...
the base is too large for any of
the sinks I own ...

... will be testing several platforms
such as Mana Sound Frame and Rosinante
Dark Matter over the next month or so.

The picture reminded me that David
posted below asking if anyone knew
of a source for the chimney flue
piece that sits between the patio

Any ideas, folks?

My heavy Table is on
Zipplock sandbags
on a 3/4 MDF shelf
on half inflated bike innertube
on really old hardwood floors, that usually make a lot of creaking noise when walked on. With the above measures in place, I can stomp my feet within inches of the table and get no audible boom and never any needle skip.

It is nice to be able to dance around while a record is playing. When I was a kid it was forbidden, cause it would scratch Dad's "precious" records. I guess if I was a genius I would have been working on home grown products back then and probably be in that business today... Huhh.

I've been out of vinyl for awhile, but we've got something in the lab at work I'd be checking out if I had a turntable for support. Its a marble stand designed to support precision scales used for precise measurement of reagents in the chemistry lab. Its a 5" thick marble slab about 3 feet long and 20" deep, supported by two "legs" of identical size and shape stood on their short edges. A 3" diameter steel pipe reinforcing rod runs between the two legs about a foot below the top shelf holding the whole thing rigid. Must weigh 300 or 400 lbs....

There are two "views" in terms of supporting a TT. The make as heavy as you can and the lighter is better approaches. Both provide isolation, although the "heavy" approach tends to be expensive or ugly (sorry, but patio stones do not look nice in my living room). A wall mounted platform is the best in my mind because, they are not too expensive or ugly and provide the required support. Happy listening!


My lab's got one of those too!, posted on April 1, 1999 at 15:44:27
Boy, I remember moving ours across the building to use under a Mettler AE163 to measure down to 10 micrograms. It nearly killed us! Now if only our lab would put it on surplus...hmmm.


thanx, guys. Your support is impressive! (nt:-), posted on April 1, 1999 at 23:16:35

The ideal turntable stand should provide isolation against vibration and
resonance. How about a two inch or thicker slab of granite? That should
be very resistant to vibration and resonance. I was told that marble has
similar properties as granite. I'm not a expert, but I think concrete
resonates even though it is heavy. The problem is it is not as dense as
granite or marble.

The turntable would be on top of the slab. To dampen any vibration that
might be transmitted through the slab, you could use Sorbothane in between
the slab and a plate of MDF. Some how mount the MDF on a stand. This makes
the set up top heavy, so those of us that live where the ground sometimes
shakes pretty hard, we have to build the stand so it does not tip over.

I have spoken to some people that have used a granite slab and they all
say it makes a difference. Less rumble and quieter. I guess it also depends
on the turntable. You can't improve on something that is inherent to that
turntable. I'm just repeating what I've heard for the most part. I added a
change of my own. One of them mounted his to an aluminum plate which had
spiked feet on the bottom. Then he put it on top of the furniture. Ouch.

One of these guys told me he measured the difference in rumble, etc with
test equipment. He said it was less, but I forgot by how much. I believe
he was just used a slab sitting on top of the table. He told me that in
theory, the slab is suppose to add mass to the platter.

Another guy I know bought a broken tombstone, counter sunk some holes in
it and filled them with lead. The turntable was mounted so its spiked feet
was held in place by the lead, otherwise the turntable would slide. He had
the slab on top of the furniture. It was pretty quiet when he played it.
It sold me on the slab idea. That was about 9 years ago. I still don't have
a slab. Granite or marble that thick isn't sold at mom at pop places. I
think he had a good way of how to get one at a reasonable price. A 2X8X12
inch piece of granite weighs about 100 pounds. Your friends will love you
when you ask them to help you move.

My friends think I'm a nut case because I still listen to vinyl. Even more
so now that I'm trying to find a granite slab for my turntable. Don't nut
cases be long in the Asylum?

Coincidentally my turntable (and CD player, for that matter) is on a home made stand exactly like the one pictured above. The only difference is I have a 2" slab of black granite between the turntable and the top patio stone. All this is on my cement basement floor. I was thinking of getting a real stand like a Mana. Anyone have any opinion on whether I would realize an improvement in sound?



we bought ours in south Phila at an Italian marble Co., posted on April 9, 1999 at 17:18:44

We had this Sartorous ballance that had a rediculous 0.00001 resolution, and even in the lab on the ground floor in the room with the mass spectrograph (vibration isolated floating room; and I mean the old kind of mass spec that looks like a concert grand piano on steroids) we just couldn't get it still. Great fun though, we took the company truck on an adventure in south Phila to this fantastic place that looked like a scene from "Breaking Away", where they had huge slabs of Italian marble and wet saws on excentrics with water and stone dust going every which way. The showroom had the most beautiful stonework I've ever seen anywhere, even in pictures. You just can't believe stone can look so deep and warm and in so many colors. Anyway we had them make up a few ballance tables just like the ones in the Fischer catalogue for about $60 each. They were beautiful. The lab's gone now. Wonder who got the tables? (he, he)
