The Xonar Essence One?  That's probably quite the upgrade.

 

Open up the amp and take some good photos of how your Compass looks and post them here if you don't mind.  Hopefully the issue is a simple one.

 

The single supply powering the USB and SPDIF receivers is most likely not one of the possible things that's faulty right now.

Tell me what voltages you get at the following points circled in green:

Thanks a ton for your help, I had about given up on this.  Sorry for taking so long to get a response out.

 

I'm getting 0V across those points in the first picture (the one with the 4 caps in a square pattern) and 1.73V across the points in the second picture.

 

Below as the pics for the three visible sections of the amp.

Have you contacted Kingwa?

 

He is usually pretty good with walking you through troubleshooting if you are a little bit handy with electronics.

I haven't yet, it honestly didn't occur to me.  All I did was check how much it would cost to ship back for repairs; and after picking my jaw off the floor decided that wasn't an option.

No, it is not across, which i why I did not say across, you measure the voltage at EACH point individually, so your black/negative pin should only touch the nearby screw.  I'm sorry if I wasn't clear enough.  If I misunderstand you and you got those voltages at each point, then your power supply is seriously $%^&'d.  None of the components look bad, so I assume that there's a faulty transistor somewhere or something like that.

The voltages that you should get are approximately +15V, -15V, +3.3V and +5V from left to right, top to bottom from pic1 to pic2.

 

Kingwa is willing to help over email without you shipping the unit back to him.

Sorry to revive this thread, but there's a used Compass on Ebay, and I was wondering how the first generation Compass might compare to Audio-GD's current entry-level DAC/amp, the NFB-15. Not looking for descriptions of the sound quality type comparisons. Just wondering if the original Compass would be somewhat comparable to the NFB-15 in overall SQ.

Thanks!

Bumping this because there's one for sale here on Head-Fi, and I'm wondering the same thing.

Kingwa has made any bad gear.  The Compass is a nice piece and I thoroughly enjoyed mine when I had it.   How much are they selling for?

post #955 of 956

$200 shipped (hope I didn't shoot myself in the foot by mentioning that). Like cel4145 said, I'm just not sure how it compares to Audio-gd's newer models like the NFB-15/11.

 

Prolly belongs in my thread in the intro forum, but I'm curious how the OG Compass for that price stacks up against the 02+ODAC ($215) or Yulong D100 II ($315).

I doubt that those other units will sound any better.  I highly doubt that NFB-15 or 11 surpass the ol' '09 Compass, even Kingwa doesn't seem to think so.  The Compass 2 is what compares to the old Compass, or so he seemed to imply when I asked him some somewhat unrelated questions.  You could try asking him yourself, he's a nice gent'.
