Some say too layback, the other too forward.
I have a DAC5. They use BNC input but no RCA. A big differece I find to get rid of forwardness is to use digital cable with BNC (can buy from ebay CANARE and specify BNC on one end or both). A BNC/RCA converter is no good. BNC is real industry standard for 75 ohm and it is best using BNC directly. Since then, I sold the upsampled DAC and stay with this one waiting for good SACD player.
