Jupiter 10uf and 15uf copper/paper/wax caps came in today. Just got them soldered in. Listening to my first few tracks right now. DAYUM! These are a huge, huge, huge step up over the ClarityCap MRs (bypassed with .22 Jupiters) that I was using before.
It's like switching from speaker wire made out of aluminum to speaker wire made out of very good copper. Which, in a way, is exactly what I did. At this point, as far as I can tell, there's not any aluminum foil in any cap anywhere in the signal path. Except maybe in my Auralic Vega, but I'm fine with that, for now - hahaha!
Anyway, a bit more info on the sound change - DETAILS! They just jump out at you. I feel like I've never heard this level of detail before, on any system. It's at the same level as what I normally hear from top-level headphones. And everything sounds much BIGGER! More life size. Hell, maybe even larger than life (which I love). Downsides? They clearly need some burn in, as they are a bit rough/gritty sounding with zero burn in. But even the grittiness isn't irritating, rather it just presents everything with a "Tom Waits" sort of vibe.
I'll report back as things develop.
