No offense, but I believe posting those type of questions in the DIY section are outside the bounds of Head-Fi policy - or at least answering them is. 

Oh sorry, I didn't realize that. I just thought maybe someone would want this DAC but not have the equipment or dexterity to make one, so was just curious if you guys also build for people.

I think I'm too new on this forum so I can't go back to delete that post :(

That's OK - I just don't want to see this thread deleted. We probably have stretched the rules already a couple of times, but when you start talking about selling ready-built products, it turns into a commercial activity almost immediately.  Deleting a thread has happened before (not to this thread, but similar ones).

Line 21 you specified the C0805C225K9RACTU as a Ceramic 2.2uf 10V X7R 10%. I believe you meant C0805C225K8RACTU which has the good values.

C0805C225K9RACTU is rated 6.3V. Not that it matters that much I know... But I just try to help in my way...

The funny thing is that the 6.3V costs twice the price of the 10V...

Will it make a difference? Otherwise, it's time to go scrounging through the part drawer again. Am I right in thinking the only difference is the voltage rating?

P.S. The replacement front plates are at the anodizers now.  Hopefully, I can get them to the laser-etchers next week and then we're off and running!

w00t!

  Greetings everyone. New here.  I just built a couple grubdacs and am pretty happy with the experience and results.  Can anyone who's heard both the pupdac and grubdac describe the difference in sound quality?  This looks like a neat kit.  

Hi guys, I'm new here so excuse the newb question: what is the advantage of this low-powered (USB) amp compared to an amp that gets plugged straight into the wall? No need for a dedicated PSU? I would think AC powered amps get more juice to run the amps.

This is a DAC, not an amp. There aren't many low amps that run off of USB that I can think of, most are battery for portable use, or have a power supply plugged into the wall for desktop use.

If you are referring to the PupDAC, it's not an amp at all and not designed to drive headphones directly.

Anodizing looks real good on the replacement front plates.  I'm carrying them to the laser-etcher tomorrow.  Hopefully, we'll be ready to go by mid-week next week.

PERFECT! I defend my thesis on Monday!
