I'm really looking forward to your comparison. This should be interesting.

Little Band Big Jazz is a favorite of Robert's audio check out CDs. When I first purchased it about 8 years ago, it didn't sound great, with a hashy horn section. However, after installing myriad Stillpoints on all my equipment, it cleaned up. Then the SR upgrades and upgraded cabling really made it sing. The Bryston BIT-20 was of lesser improvement (talk about price/performance-not). If this CD doesn't give you a sonic and musical lift, your system needs a lot of work. |
I like the Mad Scientist's invitation to submit the kookiest theory behind the BlackDiscus because, due to commercial considerations, the Mad Scientist is unable to explain how the BlackDiscus devices work. Examples are "The Alien Technology Explanation", "The StarFleet Explanation", and "The Dark Matter Explanation". Not so with Total Contact. Everything is explained so the user can understand why they are spending their money. |
More on electrical contacts from our good friend Wikipedia. https://en.m.wikipedia.org/wiki/Electrical_contacts Excerpt: Electrical contact theory Edit Ragnar Holm contributed greatly to electrical contact theory and application.[10] Macroscopically smooth and clean surfaces are microscopically rough and, in air, contaminated with oxides, adsorbed water vapor, and atmospheric contaminants. When two metal electrical contacts touch, the actual metal-to-metal contact area is small compared to the total contact-to-contact area physically touching. In electrical contact theory, the relatively small area where electrical current flows between two contacts is called the a-spot where "a" stands for asperity. If the small a-spot is treated as a circular area and the resistivity of the metal is homogeneous, then the current and voltage in the metal conductor has spherical symmetry and a simple calculation can relate the size of the a-spot to the resistance of the electrical contact interface. If there is metal-to-metal contact between electrical contacts, then the electrical contact resistance (as opposed to the bulk resistance of the contact metal) is mostly due to constriction of the current through a very small area, the a-spot. Contact force or pressure increases the size of the a-spot which decreases the constriction resistance and the electrical contact resistance.[11] When the size of contacting asperities becomes larger than the mean free path of electrons, Holm-type contacts become the dominant transport mechanism, resulting in a relative low contact resistance.[12] |
