Oh yeah, definitely worth the price.
Something very important that never seems to come across in any of the websites. The BDR vibration control approach is modular, flexible and progressively complimentary. In other words the stuff is designed to work together, and the more, the better.
The first and most cost-effective step is three Cones under everything. The next step up from Cones is Pits, Pucks or Those Things- but they are all slightly different versions of the same thing, basically a pad or base that spreads and improves the effectiveness of the Cones. A Cone can go between the component and a Pit, or be screwed into a Puck and placed under the component. The improvement either way is big but like everything else you just have to experiment to find which way is bigger. One thing you learn doing this, the conventional wisdom about points and vibration flowing is just bonkers.
The next step up from this is to add three more Pits or Pucks. So at this point it goes component, Puck, Cone, Pit. Huge improvement. By the time you get to this point you have added something like $500 in BDR but have a component that sounds something like $2500 better.
Only when you get to this level does it make sense to go to a Shelf. Then you are back with the same deal of adding Cones and Pucks under the Shelf. Doing the same thing only now at an impressively higher level as the Shelf drops the noise floor, grain and glare letting you hear impressively deep into the recording.
I know everyone says that about everything. But the Cones alone deliver the same, only less, but enough so that at only $60 for a set they are still one of the best bargain tweaks in audio.
