I'm getting similar listening times with Powerex 300mAh 8.4v NiMH rechargeable batteries to that of a Duracell Plus 9v Alkaline battery, so I'm happy. I was tempted by the ipower Lithium Polymer 520mAh battery, but they're about £20 each vs. £9 each for the Powerex. For £18 I get 600mAh (although that involves carrying an extra battery of course) so in a sense I felt the powerex batteries represented better value for money.

I'm using my Stepdance to power the HD 650 while my OTL Tube amp is being repaired (Little Dot MK IV SE). I think the Stepdance does an admirable job. In terms of detail retrieval and bass impact, etc., I would say the sound is comparable to using my UM3X with the Stepdance, so this suggests the Stepdance drives the HD 650 well. With the HD 650 I get the added benefit of more 'space' in the music (bigger sound stage, 'airier' sound, etc.) thanks to their open design over the IEMs. I didn't get to spend much time with the HD 650 and my tube amp (which wasn't burnt in), so this can't be treated as entirely accurate, but I recall the Stepdance held up well against it. The main difference being a solid state sound vs the touch of gold offered by tubes - bass might have been more present on the tube amp also.
