Hi Volleyguy,
I just stumbled on the update on the jupiter copper foil review by Tony Gee and he gave it a very good rating.
I just so happened that i ws toying between the jupiter and cutf on my digital input and concluded the same, that the jupiter was one of the most balanced caps that does all areas well enough to make it my universal cap to use. It does'nt beat say the cast, cutf or tftf in certain areas, but does everything very well. I have a very itchy feeling it would work very well in the tweeter blocking function.
I rolled the vcap tftf, cast, mundorf silver oils and silver gold.
The vcap tftf was the most extended and linear sounding, the silver oils were a very sparkly but also had a disorganized and slightly messy upfront staging. The silver golds were strange, had good depth, calmness and quite natural sounding, ultimately lacking extension. The cast were good, detailed, natural but actually feel it strength radiates from the midrange out but fall short on the top amd bottom frequencies.
The cast works for me as the this a small value cap in my tweeter crossover which i left the tftf there and believe it has a good synergy with the cast not making it too dull sounding. I wpuld strongly feel, full cast would not be what i want, it probably works great for a dull sounding setup.
Even the mundorf silver or silver mix definately has more detail in the higher registers.
Again, the choice of solder plays a good part in getting caps to work synergistically in any given application, if you have a chance, wbt, oyaide solder works "better" with a cast of maybe your RS. I have just tested the mundorf supreme sikver gold solder, i leaves a very similar sonic characteristic as a cast cap. To my ears, lacking it both the extension and gaves a nicer midrange.
You might want to look into psu and grounding to get less noise. Focussing just on swapping caps in the tweeter cannot be a cure all and you may have to sacrifice some more sparkle by adding 2 casts.
I now focus on getting a balanced sound over focusing on getting great mids with one cap choice, or more brilliance and detail from another cap choice etc.
The virture of the cap with the best midrange, always sacrifices the openess and sparkle.
A cap that excels in detail and clarity always causes a more upfront perspective and lost of the natural midrange.
I have not found any cap that does it all.
The jupiter copper is the closest, but doesnt highlight any particular range. It has become a no brainer choice for me unless there are specific areas of the sound i would like to gain a little more, thats where the cast, cutf, tftf and mundorf would have to be called for duty.
Imo, the cuft is closest sounding to the cast, not nearly as natural but is what i would class as a consider a midrange centric cap which has a very clear and prominent midrange details. So much so that the clarity cannot bring out some euphony in the vocals and midrange texture.
Do make it a point to take note the effect of the tweeter cap has on the bass, yes a warm less extended cap on the tweeter takes away some dynamics ad low extension on the bass noticeably.
