Yea I am with qusp on this one (with a Q) I would stick with the films. No electrolytic's here. Nugent actually suggests higher quality surface mount caps. I will see if i can needle a brand name out of him. Installing those blue Vishay's looks like a real pain unless you do them before the Blackgate's go in... but I sure do like how they look!
|I pretty much like everything that Chis VanHaus sells including the V-Caps and I am positive the new copper teflon's are another leap forward in signal transfer. However when passing a full range signal round is round ... is sounds round. This is actually a pretty big discovery and I encourage you to re-evaluate you position by further research, don't box yourself in. Now its always possible this effect is subtle in your rig for whatever reason.|
135DNR for source and preamp/headamp @
frequency response of 0hz->25mhz
Equivalent input noise: 0,6 µV
Signal to noise ratio: 112 dB at 1 V out (this is the spec for a single stereo amp, but i'm running 2 in dual mono bridged, so the spec will be significantly better)
Dynamic headroom: 129 dB (ditto)
Slew rate: 1200 V).
my headphones are 119db at 1mv
my heavily modified biamped active monitors are around 98db, but they could use some improvement, thus my next active monitor project
^^ just for reference, not getting into a pissing match, I have no doubt your speakers are more revealing than mine (particularly of soundstage character), thus my drive to make my own; but for detail retrieval the JH13 slaughter any speaker I have ever heard, tho some particularly stunning ATC actives (25K worth) sure give them a run for their money
but the chances of me doing to much more capacitor research are fairly slim, one dac is DC coupled and the other is transformer coupled. knowing me tho, now that you have mentioned it, I will find myself unable to resist the curiosity.
|In my system it is clearly evident, this is not a small difference. With 100db open baffles this is blown up like a microscope, the soundstage takes on a completely different presentation with the flat caps, much like proper output transformers. Speaking with Chris Young there are no differences in construction material between the orange Jupiter's and the new vintage one except they are flat wound. I encourage any of you with Jupiter's to take the Pepsi challenge and try these new flat ones.|
|Now if we could encourage Mr. VanHaus to build some flat copper teflon's the superior dielectric would probably set yet another benchmark. I just wish every hobbyist, manufacture (and engineer) was as open to new ideas as TeraDak is.|
|Ok, the cast Duelands sure do look round to me but the internal construction may still be flat wound or maybe something even more exotic. However we are now approaching silver transformer land pricing. At what point do we say stop and cry ... Uncle! Lunar landscape soundstages aside, it sure is exciting that the lowly capacitor is now maturing into transformer like sound in coupling applications with the advent of the "new" Duelands, Jupiters & V-Caps. The advantage being even the layman hobbyist can easily experiment and decide for himself.|
