ULTRA Diamond Series

The Ultra Diamond is our first twisted pair cable, combining two of the conductors used for the Reference, each with their own shielding and insulation. Unlike most twisted cables, we use no external sleeve, eliminating extra, unnecessary material and creating the Ultra’s distinctive rope-like appearance. The second silver-gold solid-core provides a significant reduction in ground impedance, helping to lower the system noise floor, as well as anchoring the time domain for much better rhythmic integrity, phrasing and musical flow, whilst still maintaining the Diamond mantra of minimalist construction and minimum losses to mechanical interference or dielectric effects. The frosted acrylic blocks on each cable ensure its authenticity, with individual serial numbers and certification, ensuring that your Ultra cable was manufactured and terminated to our exacting standards in Crystal Cable’s Dutch factory. 

Available cable types are: Interconnect, AES/EBU and S/PDIF Digital Interconnect, Speaker and Power cables.Available connectors are: RCA, XLR, Mini Jack, 5-pin tonearm, BNC, Spade, Banana and AC Power (EUR/US/UK)
