Yes, but not on this DAC kit.

Basically you have to try them for yourself as its difficult to pick a winner, its system dependent.

If you want a very generally summary. IMO schottky has less grain, but can sound less dynamic. However there are many schottkies to choose from, the higher current versions tend to have better dynamics.

Regular 1N4007 are pretty good.
Fairchild stealth diodes didn't do it for me. IMO sounded worse than 1N4007.
But really I think its a personal thing. When it comes to diodes I really think you have to try them for yourself to know what works in your system.

I have compared some measurements from a functioning CS8412 chip against the CS9416 chip in this DAC.

I know I am not comparing apples to apples, but as far as I can tell, the following pins are the same function on each chip:

CS8142 pin 12 (SCK) 2.4VDC versus CS8146 pin 24 1.1mV (& 0.01V AC)
CS8142 pin 26 (SDATA) 1.2VDC versus CS8146 pin 26 0mV (& 0.02V AC)

This does not look correct to me. What do others think?

(I also measured the other two data lines between CS8416 and AK4396: pin 27 0.47VDC 1.22VAC) and pin 28 0.67VDC (1.22VAC).

I have ordered a couple of new CS8416 as backup and plan to insert a new one when they arrive.

Any suggestions for anything else to check? I don't have a scope and only a multimeter.

However I do plan to buy an oscilloscope. What would be considered the minimum bandwidth to buy for work on a DAC?

Any help on this would be appreciated.

Default Shorted solder joints

Hi

On the recieved PCB of this DAC I have discovered several shorted solder joints(se fotos).
Is that OK or is it a failure?

I have contacted the supplier who says that the shorts at pin 19-20 (Thumbnail 2) should not be there.

Default The prices for assembeled or not???

Just wondering if im reading this right i'm looking on e-bay and the diy kit is $43 us, and the assembeled version is $48 ? is this correct do others see it like this ? if so is there an advantage to the diy version ? because i would take the assembled one if it means that i don't have a chance to fry anything. Also this thing sounds good enough stock or is the opamp bad ? i've heard lots of different ideas on setups. I'm sure it will beat the crap i'm using now anyway. Just let me know if the prices are right thanks ?

RockON!
