Just got my silver HD5 (waiting for the cracks....), I've turned off AVLS from the menu. The "volume set" fix that can be done in the test mode menu....I assume this lets the player go much louder than it does with AVLS off. Assuming this is that case; using both the standard earbuds and some better Sony ones that I have, max volume with just AVLS off is plenty. Anymore would I'm sure damage my hearing over time. Are those that need extra volume using less efficient (and therefore quieter) headphones?
