the only thing that separates DaVa from other hiend carts is the dc supply, and like all dc supplies, they are a factor in tailoring the sound....with permanent magnet solutions you´re stuck....for better or worse
if you´re happy with the basic sound from it, I or someone else can make a similar solution like I have for the final touch...no problem as long as you can adjust the cart yourself......the added mass in my solution is about 0,65-7g, which is nada
best

I would confirm with Darius that he is sending a completed wiring loom from cartridge to tube PSU if you don’t want to mess with it. Might want to spec the length too for your setup. Mine came as “some assembly required” maybe because the tube PSU was ordered separately.

you guys are killing me.:confused:

i'm led (and pushed) down the DaVa primrose path, my DaVa is now a few weeks away, and now it seems there is a whole level of DaVa optimization that is not an option for me as a non techie.

is there a plug and play work around to get my DaVa right? or is this stuff counting angels on heads of pins territory and don't worry about it?

ok, now i feel better.:p

Mike - is same level of madness you’ll find in a Taiko Extreme thread vis a vis network infrastructure etc. Yes it all makes a difference etc but you’ll be doing just fine with the Reference straight out the box and plugged into the EY500 power supply.

Ready to align tomorrow

Rather than go the immediate caps on the headshell route with its dangerous soldering, I opted to try a 0.22uf bypass cap on the Audio Note. This is a Wima cap (modified by Ric Schultz/EVS), cheapo price but big benefit.



My soldering is certainly not the prettiest, but the sound is more resolved, instruments better separated and sound more like instruments, smidge of brightness gone, more open, hear deeper into the stage. This is not a huge upgrade but very noticeable and worth doing—and much easier than the headshell soldering challenge, which I still may get round to trying.

By the way, the wire from the Audio Note cap to psu is VH Audio.

I´m up and runnning now too and agree on increased resolution and "inner silence"
also richer/more complex harmonic structure revealed
maybe a parallell cap on the Kaisei would improve something too
first without cap
then BGSuper E in the circuit

Leif, maybe I'm blind. Where did you mount the caps? Intuition tells me that we'd want them close to the cart.

Also, that heat sink is adding quite a bit of mass cantilevered over the front of the stylus. The performance of the cart and resulting sound is certainly affected by this and not only by the decoupling caps. I'm not saying whether that's having a good or bad effect, just that it's having an effect.

put a 0,1µF in parallell with the 10.000µF AN Kaisei too
even more dynamic energy

the heatsink was just a Viking prank to trigger Mike "DIY" Lavigne´s fear for this DaVa venture......not needed at all and just mounted for the picture..... :D

at least on video the cap upgrades Leif has added are making it sound quiet like tape

to sum it up: powersupply-Cardas 2 lead Litz copper-at base of arm AudioNote Kaisei 10.000µF elytic parallelled with 0,1µF film cap.....to follow Van Alstines decade shunt theory I should test to add 1.000µF in parallell too...Panasonic Fc is a good choice for musicality...will test after a couple of days at sea starting tomorrow

I think I missed the story on the headshell with violin look. Who makes it?

Head shell porn - hopefully arriving here tomorrow number 2. First one was Cocobolo - this new one is Snakewood.

Thanks. Quite a few options. Anyone try the carbon one? Or is the 'strad' the one :)
