Anyone have experience with Soundsmith’s strain gauge?


After watching Peter Ledermann’s excellent presentation on phono cartridge design I am now quite interested in his Strain gauge cartridge. Unfortunately reviews for the product seem to be sparse and are from nearly a decade ago. I’m wondering if anyone here is an owner of such a system and if they’d be so kind as to share their experience with it. I currently have the Aida cartridge from their high output MI lineup and I want to know if the sound really is a big step up from what I currently have.

"(Incidentally, I was absolutely amazed by the sound of his monitors especially the bass response considering that they don't have a large woofer like a floor stranding .)"

This post reinforces my experience. I didn't include in my post that the amazing sound was coming from wimpy looking bookshelves!

I had Peter play the record I had. Even he was surprised.So much, he wanted to keep it! It was  a stellar copy of the David Gilmore debut album and the cut was "There's no way out of here."


And don't forget the reduced costs of l/t ownership.
So, buy a Top Wing Red Sparrow cart for $15k.
Retips every 2-3 yrs c. $10-12k
SG? $9k minus trade in for phono (that can be spent on LPS).
Retips c $1k each.
The numbers don't lie Lol.
Does Ledermann still have them 25% off?
Not SG, I believe. Never did. Unless I'm  v much mistaken.
Coulda sworn with the shutdown thing he put everything 25% off.
