The stock gain was too high for me as well with my UERM. There just wasn't enough volume travel on low-gain, so I had to send mine back in to Nick to get the gain lowered. It was a quick turnaround for me too, probably a week total, and he covered shipping one-way (I only paid return shipping). All in all, great service from Nick.
@uelover -- aren't you from Singapore? I'd imagine it being extreme expensive to ship there. Not sure why you feel entitled to a discount. If you can source the opamps locally for a better price, that should absolutely be your course of action. But to want Nick to ship you a product for cheap, and then criticizing his business practices is a bit unfair.
