I'm also using an SR Atmosphere cable (digital coax) from my transport to my DAC. Just replaced my single ended cables (Core Power Technologies Diamond) from my DAC to my fully balanced preamp with XLRs.. Based on a tip, I chose a pair of Mogami Neglex 2534 quad cables with Neutrik connectors. I purchased these from 10 Audio for only $109.
I was surprised at the easily audible improvement in micro detail, allowing more insight into the timbre of voices and instruments. I can hear deeper into the mix. Also noticed that it produced more volume and I had to turn down my volume to get a similar apparent listening level to the single ended cables. The manufacturer claims to burn the cables in for 100 hours before shipping. Depending on your system, it may be a bit too detailed- less warm and euphonic- for long listening sessions, but at this price, it's worth a shot. This type of cable is widely used in studios for RFI and other noise rejection.
