    Like new condition. I used this cable for 1.5 weeks. I found it to be significantly better than generic computer grade Ethernet cables and some audiophile Ethernet cables. It did not perform as well in my system as two versions of Revelation Audio Labs Ethernet cables, both of which are over twice the price of the AfterDark Constellation cable. Note that this cable is the Special Edition version designed specifically to be used with the B-side of the EtherREGEN audiophile Ethernet Switch. $210 USD + $21 insured shipping to US locations. Money order or Paypal accepted. US Paypal adds 3.3%. International Paypal adds 4.4%.

  3. I recently used a 3 foot length of V-Quad Cu21 to make a DC cable for the TeraDak DC-150VA linear power supply that feeds the Synology DS718+ NAS in my main stereo system. The total, inclusive of connectors, shrink wrap, and TechFlex Clear Cut nylon sleeving, was $108. Small improvements were heard in the following areas: 1. Image weight. 2. Ambient sounds. 3. Bass definition. 4. Bass articulation. 5. Clarity in background percussion instruments. Four more DC cables will be made with V-Quad Cu21 wire: 1. For the TeraDak DC-150
  4. @GuyinOz I only have personal experience with two AfterDark clocks, but, according to AfterDark, the sweet spot in their clock lineup is the Emperor Signature level: This is where the Emperor Signature falls in the lineup:
  5. Thank you for the link to your excellently detailed review of the Emperor Double Crown and subsequent posts. Addressing your questions and comments: 1. Prior evaluations have shown that a clock's square wave shape can depend a lot on the cable. Furthermore, I have not found reliably consistent evidence that a squarer wave shape always correlates with better sound quality. However, @JohnSwenson noted that irregularities in the square wave shape can be an indication of impedance mismatches, which do affect sound quality: https://audiophilestyle.com/forums/topi
  6. Part 1. Introduction The stereophonic performance of an AfterDark Giesemann Trifecta Emperor Double Crown 10 MHz clock (AD EDC) ($2681 USD ) was evaluated in my main home stereo system. The AD EDC was purchased as a performance enhancement accessory for an Uptone Audio EtherREGEN (ER) audiophile Ethernet switch. The AD EDC's performance was compared to that of a BG7TBL 10 MHz clock ($85 USD), an AfterDark Gieseman Queen 10 MHz clock ($751 USD), and the internal clock of the ER switch, a Crystek CCHD-575 25 MHz clock. The ER retails for $650 USD. Phase noise specifications for each
  7. Part 1. Introduction A 2 meter length loaner sample of the new AfterDark (AD) 75 ohm Giesemann EVA BNC-BNC clock cable was evaluated in my two channel stereo system between the AfterDark Emperor Double Crown 10 MHz clock and Uptone Audio EtherREGEN Ethernet switch and between the dCS Puccini U-Clock word clock and dCS Debussy DAC. The AfterDark clock cable was compared to my previous reference clock cable, a Revelation Audio Labs (RAL) Prophecy Cryo-Silver BNC-BNC 75 ohm digital cable (2015 version). The AD loaner clock cable, and a second AD clock cable, were purchased during the
  8. The Rossini is a word clock, which clocks each digital sample of the devices connected to it. The AfterDark clock is an external 10 MHz reference clock, which replaces the less accurate internal clocks of the devices attached to it. The word clocks made by dCS and the 10 MHz reference clocks made by AfterDark serve different functions and are not interchangeable. To use a word clock, a device must have a "word clock" input, or be able to synch to the word clock via some other connection type. To use a 10 MHz reference clock, a device must have a 10 MHz reference clock input. Having

  10. The plot is a logarithmic scale on the horizontal axis, where every division is a power of 10. At the far left, we have 10^0 = 1 Hz The next division is 10^1 =10 Hz There are spuriae (spikes) at 10 Hz which obsure the measurement because the descending curved line is "interrupted". You have to visualize, or draw, a continuous curved line that has been interrupted by the spuriae. You can then see that the continuous curve intersects the 10 Hz division at about -143 dBc/Hz

  12. You can go to an automobile dealer and order two automobiles of the same model, with the same body style, same interior, SAME ENGINE, yet with different transmissions, different suspensions, different brakes, different wheels, different tires, and different engine tuning. It would be incorrect to say they are the same automobile, even though they share most of the same parts. The acceleration, braking, cornering, fuel economy, ride comfort, road feel, interior noise level, overall automotive performance, and PRICE will be significantly different. To the casual observer, the automobiles will ap
  13. I did not/do not rely on short term aural memory. My evaluation methodology is based on making maps of the relative positions (lateral, front to back, and vertical) and relative sizes of all the sound images in the sound stage and then making notes of the quality and characteristics of those sound images. I do not listen for "differences". Blind tests are more suited for people who are not experienced and proficient in stereophonic perception (sound localization, tactile perception, and being able to describe the character and quality of sound). Such listeners will only be able to
