I have had to use $15-25 ebay dock line out lately, and I thought they were an improvement over headphone out, BUT last night I tried my new Jumbo Cryo X silver iMod dock for the first time.
I didn't have this much improvement with my mini cryo dock for non-imod, but this dock is FANTASTIC, even without an iMod yet. My Tomahawk makes so much more bass now than before, everything is smooth, and I lose nothing in return!! I may not have been convinced before, but I am now a believer...
I can't highly recommend this enough. You must run, not walk, to your computer and order one. I didn't hear nearly this kind of improvement with my Cryo'd Moon Black Dragon cable for my HD600. I'm almost afraid to hear how much better my iPod is after RWA is done with it
Whew! I feel beter with that off my chest.
