Feedback on the setup? I absolutely love it. Used Dice and a USA Spec PA-12. Dice was crap, USA-Spec was average, good functionality but questionable audio quality.
The Intravee II & KCA 420i is perfect in every way. Awesome functionality and perfect audio quality. The only downside is that you need to get a charger adaptor for newer ipods but you can get them off eBay for like $10-20.
