Lemme try and add some things I think will help, feel free to comment, am thick skinned... fat too...

These are guidelines, as I dislike rules... I believe rules are needed when you are either selfish or in this case - cannot fathom the other person's viewpoint.
1. Thou shalt not disagree for the sake of disagreeing, or because you feel like P-ing someone off... Ja I know, but hell a bit of self-moderation is prolly a good thing... Previously we were a bit more amicable about this... but we might need to accomodate others
2. Rule of thumb, if you have to re-state what you said in earlier post, and especially going on to a third time... You should prolly for the sake of dignity quit while you still can. The person won't change his mind... rather invite him to an audiofest...
Case in point the audiophile snake-oil thread... at around page three - one might say bring your amp over let's see what she can do... Obviously there were very valuable technical comments too, would not want to chuck them out - one learns from it... but we went on for a looong while going nowhere - although I have to say it came to a conclusion, which a lot of others don't, but I got the impression it was more due to submission than conviction on the original posters part. I don't think anybody is going end up right about these things, but acknowledge the different view point before it goes out of control.
3. Stay on topic... OK I am bad with this - blame the ADD, but jeepers we mess up threads big time. Before you bugger up a thread, try and self split - like this one... just post a note in original thread: separate discussion going on here [link]
