Which Herbie's Product is Best?

Thanks for all the advice! I just ordered 4 Tenderfeet for my CD/HD player and 6 Isocups with lampblack balls for my preamp and preamp power supply.

Tenderfeet under my CDP and Iso-Cups w/ the previously available Ruby balls (3) under my integrated amp and Big Dots under my speakers. Steve has to steer me wrong with isolation recomendations. I also have used the Excellent Mat on an LP12 with outstanding results.

I use Iso cup/balls. I also believe in using 3 but on my 55 pound CDP I didn't have confidence that something bad might happen so I went for 4 for added stability. Tendefeet were too bright/brash in the HF on my CDP.

I just installed Herbie's Audio Lab Iso-cups with Lampblack Balls with the new decoupling base upgrade. Using 3 of these under the CDP, Integrated Amp and Power Regenerator. Immediately noticed a deeper and wider soundstage, bigger 3D images, increased dynamics, smoother and more liquid midrange, focus and transparency improved. Cleaned up parts I didn’t know that could be improved. This inexpensive tweak was well worth its price.
