I heard that Teddy is also making ps for vdac, it is not listed in his products,just ask him: Teddy Pardo home of TeddyCap TeddyXPS power supply for Naim Audio replaces HiCap and XPS I have built my around the superteddyreg and it is phenomenal

Can anybody measure the ouput voltage of the Little Pinky ? If possible with and without load. Thanks

Interesting - i wanted to set the voltage of my new ps for the vdac, so first i measured the voltage of the original ps. Original ps is delivering 19,1 V dc without load and 15.12V when it is connected to vdac. I measured on the pcb dircetly under ps plug. Does anybody know to which voltage...

So, finally i have little more time and i did the new power supply for vdac. I went the easier way (i am not making the new +-12v and +-5v to connect it directly inside), i just did one possibly best external ps. 1. Nice toroid 80VA 15VAC 2. Rectifier with four MUR 860 Onsemi diodes left...

I know that original psu is not the finest. I want to build one with "Super Teddy Reg" and already have all needed components. SuperTeddyReg high end voltage regulator Teddy Pardo home of TeddyCap TeddyXPS power supply for Naim Audio replaces HiCap and XPS One day ( i have very little...

No, it is not switched one. I choosed one well build regulated 12V/2A linear psu:Conrad psu Article number 510172 - 62

With original MF psu my vdac has very spacy, warm, analogue sound. My system - DPA CD Drive, or USB from Notebook, VDAC, very good tube pre based on Marantz 7, Arcam power amp, Spendor SP 2/3 speakers or Beyerdynamic DT990 headphones. On this system i can hear even the smallest difference in...

I tried this 12V/2a regulated PSU from Conrad and the sound was much worse than with the original MF small psu. I don't know why, but this is my experience. Maybe Vdac needs psu with very low impedance, and Conrad psu has high impedance ?

I have v-dac since few days and i am very happy with the performance, but - IMHO there is some lack of dynamic, PRAT and details. I think the first thing i will do will be one regulated psu, than i want to exchange IC5 and IC7, and than some caps. I hope that better psu will bring some more...

If you are 100% sure that your preamp has input caps, than you can REMOVE completely the output caps from the V-dac. If pre has not input and output caps blocking DC and your power amp has not input caps, than there is a danger that DC will destroy your speakers ! Be carefull !
