This past summer, I have been living it up with a pair of kilowatt class D monoblocks from California-based newcomer Wyred 4 Sound. Who is Wyred 4 Sound? While the firm may be new, the guiding hand behind it, Rick Cullen, has a r�sum� that stretches back to the early days of PS Audio and to 1990 with his own firm Cullen Circuits that specializes in providing OEM work for several high-end audio firms as well as a modification service. The W4S brand now allows Cullen Circuits to design and market their own product line. Darn impressed with Cullen's Level 3 mod for PS Audio's DLIII DAC I wrote up last year, I was keen on hearing more from this team.

Wyred 4 Sound offers three mono amp models: the SX-250, SX-500 and SX-1000 as well as several stereo and multi-channel amps. My review loaners were the SX-1000 monos rated at a whopping 1.140W into a 4-ohm load. This pair of lightweight compact boxes does not look at all like traditional high-wattage solid-state bruisers. By using switch mode power supplies, the bulky transformers, massive heat sinks and beer can sized caps of a similarly rated linear design are unnecessary. Each amp measures 8 inches wide by 4 inches high by 13 inches long. The casing is a rather utilitarian two-tone steel gray and black with a pleasantly muted blue LED on the front panel to indicate power status.
