Best optical cable from Apple TV to DAC


Need some advice on what's the best optical cable for connecting between the Apple TV and DAC? Have considered the AQ optilink 3. Budget around US$100-150.

Any good glass cable will do the trick. I've tried a few and there isn't much difference.

Best value is Lifatec Silflex glass for about $70.
I must offer you another Best value cable: http://www.uniqueproductsonline.com/6ftgltodiauc.html This cable has bettered comparable glass optical cables up to $500.00. Search the forum.
