I love the Voyager. Simply just powerful and I find that it pairs with my Shure SE420 very well. I've tried it with JH Audio and it pairs the best with the JH 11. REALLY BRINGS OUT EVERYTHING! I also heard that you shouldn't use Copper ICs or LODs with the Voyager, because it really muffles it up. I'm probably going to try using Silver LODs. Any recommendations?
