Recommendations for a good audiophile digital coax (BNC-BNC) 50 ohm cable?

Needed for a connection between DAC and clock. Most good cables out there are 75 ohm, and the 50 ohm coax cables easily available are mainly for video, with clearly poor insulation, cable quality and solidity (albeit very cheap! :-). It is my understanding that using a 75 ohm cable for this connection might be OK for extremely short distance (1-2 ft) but for not recommended for "normal" use (1 m or more). Was wondering if I missed something?

Rajah, Short cables (<1ft) don't have to be impedance matched for average CDP to DAC connection, but your clock provides, according to description, "a very high slew rate", making it necessary to match impedance.  Also, this cable normally should be >1.5m, but because of this high slew rate 1m should be fine.  You can find 1m BNC-BNC 50ohm cables in Digi-Key or Amazon, like this one:
