Although MANY great designers don't care about balanced operation (Conrad Johnson, etc.), I do. The solidity of XLR connections and the low noise/impedence has served me well in pro audio, and I was wondering aloud (here) about what was out there when the Kavent dude contacted me. I bought one of their S-33s (exactly the same preamp as a Vincent SA93, just different cosmetics) and am utterly amazed at how good it is, and it matches well with the XLR inputs on my Jolida 502p (and a Forte' 55 before that). Unfortunately the Kavent people have disappeared, but my preamp happily remains...a fully balanced design all the way through.
