hmmm...I have the original BTR1 (well the version that has aac) and it's been essentially flawless for me. I love the thing. I'm very tempted by this new version simply based on the 50% increase in power output. That should be enough to drive my AKGs nicely... ...and apparently retailing at US $49.99?? Wow...that's cheaper than the BTR1 isn't it?
