I have an 834P and a friend has the JC3. Both are great phono preamps; both of us use Lyra cartridges, me an Argo i, he a Kleos. I love the warmth and midrange afforded by tubes and I recently retubed it with the current version Genalex 12ax7s. His system is an all Parasound JC1, JC2, JC3 set up and the tightness of the bass response is exceptional. You can't go wrong with either phono stage, it's simply a matter of what you're trying to achieve sonically.
