sbrown, Yes, I noticed that they seem to have replaced all the 2uF output capacitors with 4uF values. I got this from poring over the photos on their website. Thus I cannot see whether truly ALL the 2uF caps are replaced with 4uF values. Perhaps you know.
thekong, The in-circuit coupling capacitors are all 0.22uF values and the output coupling capacitors (which value is used in the Janus both between its phono section and its linestage and at the output of the linestage) are all 2uF in the "plain" Janus, and as noted appear to be 4uF in the Signature versions of both the Janus and the Rhea.
I used TFTF Vcaps to replace all the 0.22uF values, which is a huge upgrade over the REL metallized polypropylenes in the plain version of the Janus. Then I used some polystyrene film and foil capacitors, made by the now defunct PASCAP company (Pacific Audio Supply), that I happened to have in my stash, to replace all the 2uF REL polyprops in the Janus. Those PASCAPs are positively wunderbar. I originally purchased 36 of them (mixed, 200V and 250V ratings) to build the needed capacitance for a speaker crossover which I later tore out of said speaker. I quite accidentally found out how good they are in electronics by installing a few in an old Quicksilver preamplifier. It's very difficult now to find polystyrene film and foil capacitors in values above 1uF. I don't quite know why Aesthetix chose to increase the output capacitor values to 4uF in the Signature types; the bass is really excellent in quality and thunderous in the refurbished Janus. But hey, more capacitance can't hurt.
