Thanks for your continued thoughtful posts, Les. Some folks see the QC issues as purely "cosmetic," but I think you and I agree that they are indicative of more fundamental problems. And I that's certainly not a criticism that I would only make against audio-gd. As for safety, I just want to make sure that no one is concerned the equipment is going to start an electrical fire or anything like that. One issue of dealing with a China-based manufacturer with no significant presence in the US is that the consequences for putting a dangerous unit into commerce are minimal and our means of redress limited.
