Gentlemen, I appreciate your responses. They have helped a lot.
In this particular case I am looking at a Lyra cartridge that was re-tipped by Soundsmith. I have not talked with the seller yet, but I am assuming that the workmanship is good, but Soundsmith probably did not use Lyra authorized parts, which if correct would likely mean that the sound profile of the cartridge could be somewhat different than a factory built Lyra. Do you concur or do you think I am off base?
Thanks.
