As far as jupiter goes, I think there were QC issues with the square caps. Jupiter still makes cylindrical 10uf copper foil in oil / beeswax capacitors, but they are ~300 bucks per piece. Soooooo gl with that.
Sorry to necro this old post, but I do have a question you might be able to help with:
internal hookup wire:
any suggestions after weeding out the snake oil? I could easily build the amp with what Bottle head supplies, mind you, which is Alphawire 22awg teflon silver coated solid copper; some CAT5e for signals, and some shielded twisted pair cable for power. But the quantities they supply in the red, black, and white Alphawire are limited such that they won't make for much other than direct point-to-point wiring. That pretty much leaves out stringing those wires any other way, which I can live with if I have to.
I've searched for the 22AWG Alphawire of course, but no one sells it by the foot; only 100ft+ rolls @ ~$100-$200 prices, which I may opt for anyway given the caps I'm about to discuss.
Btw, the parafeeds are 10uf. If the stock caps don't make me happy, yup, the options I'm thinking about given my budget and what I've learned thus far are:
Intertechnik Audyn True Copper Max MKP 630VDC - 2% tolerance
Miflex KPCU-01 600VDC - 5% tolerance
Both of them are rated fairly well by Humble Homemade Hifi
, and expensive. Duelunds, Jupiters, VCAPs, and Auricaps are also in the running, but I haven't made up my mind about them yet, though I have checked what they have available in ~10uf; and Auricaps are the least expensive proposition of them all.
That said, Mundorfs are out because of what I've read of others' experiences with them in the amp.
Lastly, I'll build the amp more or less stock first (other than replace the wiring if reasonable), and listen to it through burnin before going with the more premium options. I'll also probably be pairing upper end FOCALs with the amp given its output specs and what I've read elsewhere about the pairing. Unfortunately, there is nobody near enough to me that allows for testing different headphones before purchase.
