AES/EBU cable length; CD to DAC- 1.5 m or very short?


I an running a 1.5 m cable between a CD transport and a DAC, however, because of a rearrangement of gear I can now us a .5 m cable between the CD transport and DAC. I am aware of the argument that a minimum of a 1.5 m cable should be used between transport and DAC, as propounded by Steve Nugent. I also have read that if you can go really short, that is not only OK too, but perhaps even better. 

Theory is fine, but wondering what peoples' actual experience has been. Keep the 1.5 meter length or go to .5 meter? I have been and will continue to be listening and comparing for myself, however, I am curious about other folks' experiences.

Short cable allows to avoid reflections. The common rule is to use cable that has propagation time shorter than 1/8 of transition time one way, making it about 2ft for 25ns transition time (assuming 5ns/m propagation time). I would not go more than 1 foot, since internal connections inside of the transport and DAC also count.  If it is not practical than go 1.5m-2m.
