I was looking to upgrade my phono stage for my Lyra Kleos. Modwright and some others were on the list. Instead I bought a Sound-Smith Sussurro MKII Gold, Sound-Smith's MC phono stage, and an SBooster power supply. I was able to buy a demo cartridge from an authorized dealer at a significant discount but with Sound-smith's retipping policy it was a no brainer.
I have had both the JC3+ and the Herron. What I have now is more musical to my ears. It may just that I prefer the SS to the Lyra.
