Toslink Cable Upgrade?


Would like to know if anyone has tried using an upgraded toslink such as Audioquest, Kimber etc. between a Direct TV receiver and preamp/converter. Am currently using a monster toslink and would like to know if the sonic improvements are noticeable.

Upgraded to a Transparent Toslink, hum, if the wind blows correctly and the moons are aligned, maybe... a tad better

Can somone enighten me to how optical works, or give me some web sources, because my searches are not really coming up with much. The application that I plan to use it for is recording from portable CD player to MD player. I assume that is toslink but I am not sure. I think I need a cable that is round at both ends, ie. not square on one end and round on the other. I have also been told that optical is better than a 1/8" to 1/8" connection. I know that what I am talking about isn't exactly hi-end, but any input would be greatly appreciated.
A guy at the local "Hi End" shop informed me that the only difference in Toslink cables is the connectors. The better cables have a connector that has a tighter seal. This is about light traveling from one unit to another, if the connection is not totally tight, you could literally lose information during the transmition. I have the Straightwire $50, it sounds better and the connectors snap a little more secure than a friends phoenix gold.
