Clear Reflection is a warmer and more forgiving cable than Clear. I tried Clear in my system and somehow did not like it. It was too "clear" for my taste. Mind you, I have probably used most Cardas cables in the past and did prefer Golden Cross to Golden Reference if that gives you an idea of my leanings. I still think the Golden Cross is my favourite all time interconnect and nothing quite beats its midrange portrayal - not even the Clear Beyond.
However, you like Clear so another Clear could very well work for you. I think Cardas describes Clear Reflection as a cross between Clear and the older Golden Reference - that is quite an apt description. So I guess if you would like more warmth in your system, go with the Clear Reflection but if you would like more of the same, then go with Clear.
