Naggots, I'm using the optional CIAudio V9.0 power supply $275 with my 170i, I don't think it made as huge a difference as the dealer claimed, however there was slight improvement over the wall-wart. Will these voltage regulators you speak of still provide an improvement even though I significantly upgraded the power supply? Do you have more specifics about these regulators and their installation? I'm quite handy with a soldering iron, is this something I can do myself or does Burson require you send in the unit? Thanks, I'm interested in learning more about this!
