Those wima caps you can get at eBay or your diy speaker shop. At this shop they have polypropylene types

Like I surgested at the first page of this thread the electrolytes at the output stage are 100uF electrolytes is the signal path are bad, replace them with polypropylene 2,2uF, yes they are big but I asure you your dac will sound much better. Goodluck

       Hello all,   Changed my Opamps in a Chinese Da converter, i did not have read all topic pages and maybe this dac has been seen before. years back i already had a V4 opamp and was very please with the change. Now in this Dac i have put in the V5 in the current-Voltage stage right...

Yes the cover is a problem. But i think i make an other cover, witch is higher. The bursons realy make the dac better listing to Those bursons preform very well and far behind the standard opa2604 opamps. Far more detail getting out of this dac.   Yes this is the improved version...

Quote: Bit late reaction but better react then never comment   But... are they really worth their lofty price??? I was a little sceptical but ones inserted , they will not be replaced with those plastic opamps   More then over 10 times i feld realy into a shock, by the first...

I did get in the burson opamps, only thing is the casing those opamps are a lot bigger. Burson opamps wooow i was realy shocked about the difference i now hear. Loads of more air around the speakers lots of detail never heared came out of the opa2604 Depth is amazing dito weightness i now...

Bursons are not as small a normal plastic opamps, true   But it ain`t be difficult as long as you don`t mixup the pinning from 1-8 (4 each side)    

C3 and C4 caps. But, original values are 47 µF   Those are over over killed value for the maker of the v-dac to ensure you can drive the v-dac to all kinds of amps But a value of 2,2 uF MKP cap will be enough to get enough bass.     Why MKP i already explained it in the tread...

Bought the DA02 Have let it run 7 days after first hour of listning. I found the tube output nicest sound (less accurate 0.1 % distortion) On SS output hmmm typical opamp sounding oke more detail but less musical. Headphone is very poor quality, loads of white noise, i think a cheap...

still opamps are opamps and discrete sound much better What dac will have discrete outputs?

Cable`s ...all devices needs there break in time, thats`s why rich people turn there stuff back to the store "it doesnt sound right" Stupid ones

All im saying is IF you use the cable with the adapter (bnc-rca) you still resieve those reflections. IF you use the cable without the adapters strait to the devices then you got a good connection almost without any reflections. So yes the devices need to have BNC to both ends, if you use...

Cable can be perfect i agree But not the adapter, it is a way to sell it, course a lot of users don`t solder out there connectors in the cases of there devices.   If you take the cable with both ends full BNC i think you got a good way to make it work. But with those adapters ... i wont...

For the one that is made for rca , i still call it B.S. For the one that is BNC i had not seen it, and you where right.   http://www.highendcable.co.uk/Stereovox%20XV%20Ultra%20Digital.htm     This picture is clearly a RCA type and will never be 75 ohms, if they realy make a BNC...

Impossible   The rca pin is too big you never get 75 ohms impedance like BNC Period   It`s a good way to get very rich by selling nonsence   Only solution is de-solder the old rca connectors and replace it all to BNC 75 ohms then you hear a desent change , more depth more...

Quote:   What has this site to do with modifying V-dac`s? Happy i`m not married  

Lmao you pointed it well, patrick       By the way i build NOS TDA1543 but not with 4 dacs but 8 dacs   V-DAC modified with better opamps comes real close to the TDA1543 *8   not *4 you only have halve a bit resolution more instead of one bit.   It is all what you find out on a...

So there are no audiophile`s here?   looool   http://dutchamps.webs.com/   Your quote: with this power adapter i never experienced any heat issues so often described by some of yous. the V-DAC unit itself never got much warmer than slightly over skin temp.   If you look at the...

Sorry m8 mine has burned some ics out and dont use it Want to restore it much later on Why dont you set a multymeter on the pcb to measure the voltages   Cant help yyou right now   Note some dude here placed the schematic here maybe he found the value read back some topic pages

Saying that i dont understand how it works, fine. You CAN look into my brain your smart or a Paragnost lool   Oke Your making a point a was a bit too quickly but sinds your a belgium guy. Why didnt you explained it into ducth on PM. not smart LOOL   Back to topic   I see now...

  Quote: Coupling C`s can help, only if the value is about 10% of the main cap less will do almost notting. This idea was born in the past when caps where not the today`s standard Like polyester Caps by-passed with a mkp (those where unplayable in big ones 1978)   Silver is a...

No problem m8 i have enough google links found in all those years   Amp Ohm FP-CA-AU 630VDC        price?   I use audyncaps from intertechniek ( germany) in my tube amps.   Price differents is too big to exchange then to mundorfs  (caps in signal way )   pre-amp line          ...

A dutch guy i invited to mod his V-DAC at my place. He readed my comments here and knew i was Dutch Have changed little components like the NE5532 Opamp and output caps C3-4 Brought with him a powersourse specially made for the V-DAC. This company had made a improved psu don't know the...
