DaVa FC-A1 a field coil contender

[Bart77]

I just used a heavier gauge twin cardas copper litz wire from tube rectified psu to near tonearmbase...there I hooked it up to an Audio Note Kaisei 10.000µF capacitor as last filtering stage as close to cart as possible
then I hooked up the enclosed thin silver dc wire from Kaisei and along the arm tube to the dc terminals on the cart
result more body and slam
Audiophile Bill did too and experienced the same(actually he was first)

Thank you.
Are you writing about this capacitor

CAP-100-R-10000U-63V: 10000uF 63Vdc Audio Note Kaisei POLAR Electrolytic Capacitor

Is it a chance that any other with 10k uF can be used ?
As I have “two left hands” to any electronic works - would you be able to present it on some photos or scheme? Apologies if I ask for too much

Imagine a constant wire from PSU DC output to cartridge DC pins. All you need to do is splice in the cap, as close to the arm as you can. You can replace the section of wire from cap to PSU with better quality cable if you want (thicker). I used the supplied black cable that Darius sent with my tube PSU. Maybe I will change to Cardas at some point.

Sounds quite simple.
What kind of the capacitor are you using?
I’m just thinking about two issues:

1. Type of the capacitor - 10k or 15k uF, voltage 16V, 24 or higher? Mundorf M-Lytic 10k uF 25V will be fine ?

2. Thick cable - when 2 wires it sounds like a speaker cable. Any typical power cord like Furutech or Neorech with diameter of 15-16mm will be like a stick

I have just found something like below. I have completely no idea about the brand and quality - is it ok for DaVa purpose ? This is 10k uF 16V

I will let the tech experts comment on the cap. I copied what Leif used. As for the power cable, I don’t think you want anything that big. If you scroll back a ways in this thread you can see the Cardas that Leif used. I think it was something like 21-22 AWG. My thicker comment was in regards to the tiny silver wire that is used from the cartridge.

 

[christensenleif@msn.com]

the cap most certainly will influence sound
my first was the Elna Cerafine 6.800/50v...slightly mellower than the AN Kaisei
other contenders would be Panasonic Fc, or best a 16v film cap of as high µF as possible...
also you can always start with 4700µF and double /add and stop when you think it is enough/too much

and stop when you think it is enough/too much

Applies generally to all hifi.

i read about all this DIY adding wires and capacitors and such things, my eyes glaze over. what have a gotten myself in for?

i will hope that by the time my DaVa arrives that some sort of plug and play protocol exists for me to optimize this path. or maybe i can recruit a local DIY shamen to apply blessings for me for this stuff.

You have done 40 years in normal hifi - if you get your teeth into this you can keep your interest past 100.

No worry
Once decided distance from fc psu to armbase, the "harness" can be made anywhere in advance.The intented arm can be wired external or even internal by someone capable, for the dc supply. The cart obviously have 6 as opposed to 4 pins

Mike, you're aware of the phrases "all in", and "in for a penny, in for a pound"? Well, soon you will be.

 

[DasguteOhr]

have you tried li accu with a buffer elko, advantage no ripple voltage from the power supply? Like that

On the up-side, by the time you receive the product, a better version, with different wires and capacitors will be the new goal post ! Just marvelous !

 

[christensenleif@msn.com]

what a dumb comment; the product is pretty stable, there may always be ways to improve it´s working conditions, as there are with amps , speakers and anything else

 

[Lagonda]

It is a wonderful business model of coarse, continues "upgrades" secures a ongoing cashflow without having to secure a lot of new customer. The numerous power supply upgrades inside a short time have left me in a daze already. Saw this model with the original APL products the first time.

Not tried it yet but was threatening to before Xmas before beer, wine and festivities took over as my main priorities lol. It is in the plan to try though.

 

[Audiophile Bill]

I wouldn’t get too hung up on potential advances. The point is the standard DaVa (not reference) with a solid state power supply is still absolutely fantastic for my taste. Yes the tube EY500 supply took it to yet another level.

In terms of subsequent filtration caps etc. That is not required but worth it if you are a madman like myself or Leif. Think of this in the same way as installing your audiophile server. Many people are happy to plug their new Extreme into their existing network and be done. Others will want to insert special switches, fibre converters, special USB cables etc. The latter might very well be worth it but not necessary to still enjoy a stellar performance.

Best wishes.

I don´t know what´s wrong with you today:
maybe acid in your Cornflakes this morning?
the powersupplies has been something some users have experimented with and nothing Darius has "developed " in several iterations as you imply
he´d prefer focus on the carts, not psu´s SUTs or even arms
I guess you prefer the business model where an American co launches some reference amps ...have them in their portofolio for a year or two, before they launch a new cost no object model, which leaves the unupgradable model in the ditch together with their clients
when you look at the DaVa pricing they´re ridiculously high value for the money as opposed to a lot of other overpriced shitty carts,priced at the if you have to ask policy..guess it gives cred in certain environments, with more cash than brains

 

[Lagonda]

I personally find most "top" carts widely overpriced, but also find the fascination with anything home made by artisan one man producers somewhat amusing.
But good luck with it ! I don't eat Cornflakes, but your Norwegian way sounds interesting !

What if this fascination is completely justified? Thinkless pressure towards products made by industry leaders is supposed to be better? I don't know how long Darius has been on the market, he has already sold some of these cartridges and they are met with admiration from all over the world. That sounds good for him, doesn't it? Or maybe you see it in the category of marketing practiced by all of us in exchange for gigantic discounts? An example is the praised on this forum, Lampizator. After all, 15 years ago, no one knew who made it up. Today it is one of the best DACs on the market - I know because I have one myself, and believe me that I have listened to many different devices. So what if I know the designer personally? Didn't it start with unit production?

 

[Lagonda]

Are you getting gigantic discounts ? The price is already reasonable, i guess Leif never has to pay for a cartridge again !
