Neo,
With apologies to the OP, I just want to make it clear that I have absolutely no vested interest in GCA apart from being a very satisfied customer. I could have as easily recommended contacting the Needle Doctor; I'm happy with them, too. I am by no means an analog expert and respectfully I disagree that it's 'lousy advice' to suggest contacting a dealer, local or otherwise. I hope the OP gets the information he needs to make an informed and rational choice.
Thanks, and happy listening,
Mark
