Weight, Clamp or stabilizer?


I have a vintage Pioneer PL-560 Direct-Drive Automatic Turntable purchased around 1980.

I'm trying to get it to produce the best sound its capable of.  I plan to order a set of SVS subwoofer feet to replace the worn feet (I have an SVS subwoofer and removed its feet and temporarily placed them on the TT base with good results).  I read an article about TT tweaks.  A few things they suggested were an upgraded mat, clamp and isolation feet.  Thing is since the TT is a direct drive I don't know how much extra weight it can take (if any), and the spindle is about 7/8 inches tall so I don't know if that's enough for a clamp.  The original rubber mat it came with is in great shape. Do I need to replace it, too? I'm willing to invest in tweaks to improve this turntable, but not interested in replacing it.

The best you can do at the first step is to upgrade the cartridge!

This is by far the most important. You can do all the tricks, but without a decent cartridge in contact with your vinyl grooves all upgrades makes almost no sense. Make sure you have the right cartridge first. Some vintage MM cartridges are great, Pioneer PC-1000 mkII was their best cartridge (absolutely amazing, look at the package).  

A good cartridge will change the sound of your system even on felt mat without clamp or weight. 

All the tricks such as mat, clamp will make some improvement, but not as huge as the cartridge. 

BTW Pioneer dist stabilizer is very nice. Micro is another top-notch stabilizer. As for the Mat i would recommend SAEC SS-300
The best lightweight clamp with chucking lock arround the spindle is Orsonic. The silver panel on top act like a button to open chucking lock. It's cheap

Practically i don’t like clamps with lock, i prefer just weight (always).

Besides the capability of isolation, does anyone know if feet with isolation properties as well as adjustment for height available??


One of the best isolation device is Audio-Technica pneumatic insulators AT-616:

Set of 4 supports 10 to 60 kg (22 to 132 lbs.) and each one is adjustable. They are big and heavy, can be placed under turntable or any audio device including subwoofers. Also can be placed under wooden platform to make the whole table isolated. The 616 model was the best and most expensive, they made cheaper alternative, but cheaper AT feet can’t support heavyweight.

For those not overly concerned about their "audiophile cred", the Orsonic was rebadged as a Monster Cable clamp. Totally identical, but for the name — and the price: ±400 for the Orsonic, ±100 for the (ugh) Monster these days.

Interesting, never seen an Ortonic with Monster Cable logo.
The original Orsonic is not expensive, 150-200 bucks.
Micro Seiki is more expensive. 

I’m new here.

How do you respond to a specific post, or to the OP’s latest post when you see it later (above more recent posts)?

chakster....Thanks for your recommendation. From what I’ve found, the AT-616 isolation feet are no longer in production. There are some sites that list used ones of a price from $600 to $800. More than double the cost of my table and cartridge.


Yes, if you will compare the price for those vintage Pneumatic Insulators to the new Stillpoints you may think the old AT is cheap :) I think you can find them a bit cheaper if the cosmetic condition is not MINT. But i agree they are rare and expensive.

So....Would the cost of the feet really be worth it given my setup? If I had a more costly table and cartridge then, maybe. I realize that setup is most important for any table. I am looking for a modest tweek that may or may not yield any sonic improvement. Certainly not high dollar feet meant for more exotic setups. Thanks anyway for your input.

The goal of the AT616 is the high weight they can support, my friends using them under Obsidian Plinth of the Technics SP-10mkII turntables and everyone who tried AT616 instead of the stock Technics feet are very impressed by the improvement.

If the turntable is too cheap for such expensive feet then i think 4 x AT616 can be used under the desk supporting all equipment on the desk (if the total weight in under 132lbs or 60kg). Such desk can be a good isolation platform with those AT616 (they can be leveled individually).

Anyway, i just don’t know a better isolation device, so i’m recommending the best one. I have 8 of them.
