Comment 1:
Have seen too many compliments about Soundsmith retipped carts. Never heard anyone say they regretted it or it sounded worse. And I have seen a quite number of SS customer comments on this.
Comment 2:
AT doesn't retip but if you send in your old cart they sell you same model at a reduced price or you can upgrade as well. Either way you save bucks, I think it is around 50 or 60% of new cost.
