Hi tnmike1,
Quote:
I'm using an inexpensive Radio Shack wall-wart unit that has adjustable voltages,up to 12v. I notice a huge volume difference at 12v. With the Denon 5000 and UM3X IEM, Idon't need to turn the volume up at all; it's already loud enough at the minimum setting. Under 9v power, the volume needs tobe adjusted. Don't know about sonic differences as i'm stll in the break-in period and sound is still "maturing" But the volume differences between 9v and 12v are amazing
I realize that it's subjective, but I don't observe a "huge" difference in volume, when switching between an 8.4-Volt internal battery and a 15.0-Volt external battery. Can you check and see if you've got your Stepdance set to the Low Current position. It's the switch that's by itself (not the two Gain switches).
I'm thinking you might have it set for Low Current and when you plug in an external power source, the volume is going up, at least in part, because the Stepdance will automatically switch to the High Current setting whenever you attach an external power source.
Thanks,
Mike
