Everyone's advice was spot on. The Muse T-amp is nice sounding, and a good deal in performance for the price. My 12 yr old son uses one with his Stax SRD-6/Lambdas. However, I agree that the Rotel is likely a much better choice, just remember to not turn up the amp past about 8-12 watts of power for the Stax transformer. You can get by with 5 watts.
On your budget the Behringer uControl 202 you pictured could be used as a USB DAC and music source to feed USB audio into the speaker amp, but it's not super resolving/detailed. A $40 Headstage USB DAC cable would be a little better (I did compare them a long time ago). But a $99 Nuforce uDAC to feed the speaker amp from the RCA outputs would better allow you to experience the extra detail of the Stax headphones than those others. It performs well above it's pay grade, and I bet it would sound good with the IE8 if you use the uDAC built-in headphone amp. The uDAC can even drive the HD600 if needed if you have to take it portable with a laptop. And, as a DAC it's not out of place feeding a $500-$1000 amp either.
