Herbie's IsoBall: Superb turntable isolation
w/ black baseHerbie's IsoBall is formulated just slightly softer than our standard grungebuster balls to achieve maximum turntable isolation performance and ultimate compatibility with parameters unique to stereo turntables. Mounted on a non-magnetic stainless steel base, a layer of Herbie's compliant Soft Fat material on the bottom helps absorb macro/footfall vibrations while remaining super-sensitive to acute micro-vibrations.
Stainless steel base grips the ball firmly; ball will not roll. IsoBall gets a good grip on the component; the component will not slide.
Because Herbie's IsoBall is compliant (has a little "squish" to it), leveling is easily accomplished, if needed, by positioning of the footers; move one ore more as necessary to achieve a perfectly level turntable support.
[ Leveling a component on compliant feet ]
Herbie's IsoBall is a natural, translucent off-white, which blends aesthetically with any decor or color scheme. Stainless steel base is available in natural or semi-flat black.
IsoBall footers can be used as a set of three or four (four is recommended for superior lateral stability, placement versatility, and leveling ability).

Message: Hey Herbmeister, I don't have any of the problems the above poster's have! What am I doing wrong? I've ordered a set of the iso-balls anyway. Just because I like the Freudian sound of them!
Webmaster's reply: I don't suppose you're doing anything wrong. With better isolation of your turntable, you'll most likely enjoy the music a little better.

Message: I have a vintage Pioneer PL-L1000. The house is on blocks with wood floors. I don't plan on dancing around the house, but if I walk near the turntable which is sitting on a antique chest of drawers, the arm does tend to jump a bit. What do you recommend to isolate this unstable environment?
Webmaster's reply: Replacing the rubber platter mat with a full-size Way Excellent II-3.7mm Turntable Mat and using four Hardball IsoBalls with bases should help quite a bit and most likely reduce or eliminate footfall issues, besides bringing out a substantially better sonic result.
For a smaller investment, four Big Tall TenderSoft Tenderfeet would most likely do very well.
If you still have footfall issues, moving the chest of drawers a little this way or that might find a more stable position.

What is all this talk about FOOTFALLS? Are you walking around the room or dancing? Sit the hell down and listen to the music.

Message: I have a new Pro-Ject turntable with bad hum when the stylus is in the groove. Is this the right situation for IsoBalls?
Webmaster's reply: Lots of things could be causing the hum. A most common cause of cartidge hum is having an inadequate cartidge-to-preamp grounding and/or preamp grounding to "earth," or very likely a ground-loop. Belt-drive turntables like some Pro-Ject models can suffer from a 50Hz-60Hz motor hum; though IsoBalls can help, a Way Excellent II-3.7mm Turntable Mat is usually the best solution.
If the hum is caused by vibrations infiltrating the turntable from the rack or shelf, IsoBalls (or Tenderfeet) should alleviate the problem. There are many varieties of Pro-Ject Turntables; most do very well in an average vibrational environment with the factory feet and upgrading to a Way Excellent II-2mm Turntable Mat.

Message: I have a 3 inch Maple turntable platform, and my turntable sits on an acrylic plexiglass base.
1) what do you recommend under the maple platform? Grungebusters or big tenderfeet?
2) what do you recommend between the acrlic base and the maple platform? tenderfeet or isoballs?
Webmaster's reply: I'm not sure why you would want to build such a totem pole to set your turntable on. Under both the maple platform and under the acrylic base, I recommend four or five regular grungebuster Dots about 1" or so in diameter as a decoupling interface. (You would want to use Tenderfeet or IsoBalls in direct contact with the turntable bottom, between the turntable and base, used instead of the factory feet.)

Message: Hi Herbie,
I have a Rega P25 and am not sure whether I should use a set of IsoBalls or your tenderfeet. I have my Rega on a stand alone platform specifically designed for turntables; the stand is spiked both onto a concrete floor and into a mdf top shelf. Could you explain the differences, if any, between using the IsoBalls or Tenderfeet in my application? What are the benefits of each of these products?
Thanks in advance,
Bill
Webmaster's reply: Hi, Bill. Rega P25 will do very well on either IsoBalls or Tenderfeet, so you wouldn't go wrong with either. Both provide exceptional isolation and decoupling with micro-vibration control. IsoBall w/Base provides a little extra protection from severe footfall issues. For the application you describe, we recommend a set of four regular Tenderfeet to go along with the Way Excellent II-2mm Turntable Mat that you already have.

Message: Hi Steve,
The turntable isolation feet aren't working as well as I would have liked for footfalls or for the rumbling associated with the light rail nearby. I've tried the tall Tenderfeet, which worked better, but I'm wondering if the Ginkgo replacement balls might work better than either? What would you recommend for extreme vibration isolation?
Thanks,
Wilson
Webmaster's reply: Gingko upgrade balls are not likely to do any better regarding footfall issues. There's only so much you can do with turntable isolation at the table itself and still maintain sonic integrity. You might look at better isolating the rack or stand that the turntable is sitting on, or moving the turntable to a more stable location.

Message: will iso balls work with my project 5.1 se mounted on a mapleshade platform?? They say to use brass /footers to drain vibration.. what will the iso balls do?? Thanks, Rick
Webmaster's reply Sure, you can use IsoBalls with the 5.1. Unless you have severe footfall issues, you'd probably do just as well with Tenderfeet. Brass cones draining vibrations don't often work as well in practice as in theory, giving you more of a "tuning" effect than actual isolation. Tenderfeet and IsoBalls will truly isolate the turntable and reduce harmful vibrations, allowing your player to more accurately and more naturally portray the recorded music, without the harsh edge and coloration that brass footers typically introduce.
(Using grungebuster Dots between the maple platform and shelf is beneficial, as is a Way Excellent II Turntable mat on the 5.1 platter.)

Message: Hi Herbie,
I've had a Linn LP12 for over 12 years and have never been able to get rid of the foot fall problem. Over the years I've tried every tweek I could get my hands on without success. Enter the Tenderfeet. Lo and behold, the foot fall problem is gone. Much to my surprise, the sonic improvement was stunning. How do you do it? you must be a magician.
I next tried the IsoBalls. Again a foot fall was gone and a different sonic perpective was presented. A more transparent and lively sound. I can't decide which I prefer and will have to go back and forth befor I can make up my mind.
Thanks for everything.
