soundsmith work on Benz or Maestro v2

My 2 year old with about 200 hours of playing time Benz Wood SH suspension is in need of attention. The cantilever lies flat on the vinyl. Have since bought a Clear Audio Maestro V2. Have only put about 10 hours of playing time on it so far. I like it but the Benz Wood SH was quieter. The Maestro V2 has a buzz just barely audible at the chair but the Benz there was barely noise when standing directly in front of the speaker. I will send the Benz to Soundsmith to be repaired but considering having more than that done. Comments I'm looking for from those who have more knowledge in this kind situation are could soundsmith turn the Benz into a much better cartridge than it already is? Could Soundsmith turn the Maestro into a better cartridge plus get rid of or reduce the noise. Sonically I like both cartridges even though they are different. I have Emailed Soundsmith and registered and got an RA number for the Benz.
