Finally got around to making some digital cables to use between my 63KI and my recently bought s/hand DAC 19. I use a shunted pot in my Bada h/amp and was shocked at the o/put level of the DAC 19. Because I lose about 6dB by using the shunt, I normally have volume at between 10.30 - 1.30 but now I can't go above 9. I don't believe the problem lies with the 63KI which has a nominal 2V o/put.
It's not possible at the moment to download manuals from the Audio-GD site - does anyone know what this DAC's o/put is?
For all those who use ACSS - why does Kingwa use these crap connectors - they are simply not nec. Take a look inside - the chassis connectors for both ACSS and digital have only one difference between them and a standard RCA chassis plug - the removal of the Teflon washer decoupling the connectors from the metal chassis. This simply means that both ACSS and digital are grounded twice - once on the PCB and again to the chassis.
So, if you must use connectors, choose RCAs that float your boat and just remove the Teflon insulating washer - solder a piece of wire (your choice) from the earthing lug to the PCB earth - now you can experiment to your hearts content to find the best ACSS sound.
However if your smart you won't use any plugs at all - remember the best plug is no plug at all, just solder from DAC PCB to C2 PCB. To facilitate wiring experiments use a piece of right angled copper wire as a PCB pin (they are crap and best avoided).
As to DAC 19's sound - I use the digital connection and in this respect, the sound is hugely dependant on the digital cable - use the wrong type and it quite frankly is poor but with the right kind of d/cable it is very good indeed. Mid's are very good and bass goes deep but lacks real detail. Using only one make of electrolytics seems to be a Chinese thing. I think that working on mods around the analogue sections will reap real benefits.
Looking to find good caps for the PSU - never heard of Nover - low ESR is only one part of the equation with PSU caps - shame I can't use my stash of Philips LL (create air and just a hint of warmth) Nichicons may lack body - anyone else got thoughts on mods for this DAC?
