I also look forward to skylab's review. But I also very much value spritzer's input. Both are valued head-fi members, and both should be given a chance to say what they need to say. It's not like spritzer is a newb with no demonstrated technical knowledge. I've read many of his posts and have found him to be very helpful in the past.
I, for one, value hearing both sides of an argument. I feel that I have the ability to decide for myself what to believe, given the information at hand. Jude, I understand your need to moderate as a moderator. But I hope you will be specific about what you want spritzer to limit, and not just shut him down period, or ask him to just stop posting. I think you have to admit that he has vast technical knowledge, and that is a great asset to your forum.
Like I said, he can be very helpful at times, but also equally spiteful.
Why don't you read his post in question? I know for certain you're fully capable of discerning when he crossed the line, and got into character attacks--and no amount of technical knowledge makes that okay. Like I said before, last year he wrongfully and publicly accused another designer of stealing. I've had it with that kind of stuff, man, and I'm definitely not alone.
For his own reasons (reasons I completely understand), he did not exhibit at CanJam 2010. There were a lot of manufacturers who did, and many who didn't.
There are few manufacturers who've traveled to as many meets over the years, far and wide, as him, though, so there's certainly no meet-listening deprivation going on with this manufacturer.
