Fikub33 Posted September 22, 2022 Posted September 22, 2022 Black Diamond Racing (BDR) Cones 3 x Mk3 and 6 x Mk4 These are great isolation feet. I used these under my preamp and DAC and Amp. BDR Cones are perhaps the most flexible component in the BDR lineup and by far the most popular because they are both inexpensive and shockingly effective. They also greatly enhance the performance of all other isolation components products. The cones are created from a proprietary compound of Carbon Fiber and Resin, with a crush point of 10,000 Lbs each. Combine their strengh with internal 1/4"-20 threading and there are virtually no limits to what you can do with BDR Cones. Two different versions are included in this listing. They can be used to help tune your system. Both versions provide imporvements over no isolation but in slightly different ways and they can be combined to great effect. The Mk3 Cone (6 are included in the listing) has a slightly warmer tonal balance, with a little extra oomph on the bottom end. Great for taming slightly bright and edgy components. The Mk4 Cone (3 are included in the listiing) is slightly cooler with greater top octave extension and less emphasis on the lower frequencies. System just slightly too warm? Add a single Mk4 Cone for a little extra air and detail. Just a smidgen too detailed? Add a single Mk3 Cone for a touch of warmth. In general, BDR Cones will work best when their flat side is against the component’s chassis and the rounded tip is pointed down into the shelf. When using BDR Cones with a BDR Shelf, invert the cones, so that the flat face is on the Shelf and the component is resting on the rounded tip. The Cones are 1" high by 1.618" wide with a rounded tip and are 1/4"-20 threaded. https://www.bdrsound.com
