For any future Jasmine owners or current owners following this thread:
I have since upgraded the Jasmine. I replaced the umbilical with Jasmine's own upgraded (blue) cable between the main preamp and power supply. The PS capacitance has been doubled, using 2200uf (Nichicon KA) per channel and bypassed with Vishay MKP-1837. In the preamp box, I doubled the existing 2200uf per channel w/the same Jamicons and bypassed with MKP-1837's. I replaced the output coupling caps (originally Solen 1.0uf) in the preamp with Robert Hovland Supercaps (1.0uf). This last change opened up the top octave (or "air") and helped in midrange articulation. The input signal wires were changed to solid silver wires. All other small wires are changed to very high purity solid copper.
Overall, the Jasmine lost a little "haze", smooth as it was, and increased its sense of dynamics and liveliness. More grip and authority is present. Image placement was wonderful before; now it lends each instrument/vocalist a fuller, rounder sense of location in its own acoustic as well as a more precise relationship to other entities. The dynamics increase is largely attributable to adding the Nichicon KA capacitors. They are very smooth and natural yet seem very "bassy" but articulate and tight. I love them. My "new" Jasmine is a phono preamp I am extremely happy with and do not care to try SUT's on. It sounds remarkably complete and satisfying as is. (Cartridges: Music Maker MkIII, B&O MMC2, AT33PTG/II and my best, favorite of all - Stanton 981 LZS. I love it so much I just purchased another NOS.)
Kids - do your mods! This Jasmine will amaze even more.
