I recently bought a pair of DH Labs Air Matrix Cryo's XLR IC's on a whim from usedcable.com to replace a pair of well broken in Blue Jeans Cables XLRs I had going from my preamp to my amp.
Before any warmup/breaking in/whatever...as soon as I put them in the improvement was remarkable. More air, more detail, better defined soundstage all while also sounding much more relaxed.
I immediately bought a second pair of Air Matrix Cryo XLRs to put between my phono preamp and my preamp....and then went back to usedcable.com and got really lucky to score a deal on a new pair of DH Labs Revelation RCAs to use between my SACD Player/Streamer (a Marantz SCD-30n) and the improvement there (over RS Audio Solid Silver ICs with KLEI plugs) was also palpable.
The improvement brought by this cables was immediate and easily discerned and the prices are almost too good to be true.

Just received a pair of Air Matrix Cryo RCA interconnects. Exceptional quality for the money. Much better than the Nordost Blue Heaven they replaced . Good stuff !!! Customer service is off the chart too.
