Use Rather neutral, so not cables to use as passive tone controls. Darren Hovsepian at DH Labs has known this for years. Both offer very high value and work well with a wide array of equipment, tubes especially. So at CES 2001, DH Labs introduced the Air Matrix interconnect and Q-10 speaker cable, both taking their place at the top of the DH Labs line. Thus, those who want to have the best cable a company produces can do so with the Air Matrix and Q-10 and not tap into the kids' college fund.
Prices vary depending on configuration, but they never reach nosebleed territory.
T-14 I had been using. DV-525 DVD player. Preamps and the DAC sat on the shelves of sand-filled Target racks, while the amps rested on Bright Star Big Rocks, as did the Mark Levinson CD player. I also used a full Transparent Reference XL setup too. Because the Audio Research amps take only XLR input, DH Labs supplied single-ended and balanced Air Matrix interconnects.
