I have to
imagine that
Clarity Cap has a series that will deliver what you are used to, at a price you can afford ( though, I have no personal experience with the brand ).
Your words nicely track what Tony Gee says about the ClarityCap CSA series ( plus
that CSA series garners the same 8+ rating as the Gen1 Sonic-Cap. I have no personal experience here with either ).
- FYI, that CSA series is quite a bit more affordable than the Auricap Xo series ( over at Parts-Connexion ).
FWIW, I usually use surplus modern-type, ( MPP in Oil ) motor-runs to deliver those qualities of "warm, musical and affordable" > though finding the needed values is usually a chore.
- Modern motor-runs can easily be bypassed with small value Film+Foil poly-type caps to deliver some extra detail if desired ( I prefer PolyStyrene vs Polypropylene for this duty since that dielectric adds a softer sort of HF >> less "etched" >> at least to my ears ).
- Coincidentally (??) most motor-runs score ( on the TonyG scale ) in that very same area ( of 8 to 9 ).
- I'll confirm that I think higher voltage (>600V ) modern Motor-Runs sound better >> simply having a better lower range with better midrange clarity ( I use a 27uF value in my Hi-Pass circuit going to my Altec 288//EmilarH500 >> Horn/Driver combo ).
