My Zero has had a small problem ever since I got it about 7 months ago where the right channel is louder than the left at low volumes. I don't usually listen at low enough volumes for this to be problem, but I'm trying to change my habits and start listening quieter. I'd like to lower the gain in the amp section so I can turn the volume up without it being very loud. How would I go about doing that?

Get an alps pot from Lawrence Chan and install it. Requires desoldering the old pot and soldering in the new one.
Here's his auctions, I've bought an alps pot from him, but I don't know if he'll sell one to aomeone who hasn't bought a zero from him.

I've never done any soldering before, so I doubt that I'd be able to install it myself. How much do you think Lawrence would charge for an alps pot?

I think he gets about $10 for it. This would be a hard project for your first solder job. The hard part is the desoldering on the crappy Zero Board. I don't know any other source for the alps pot that goes on that board. The alps Blue Velvet is too big.

Hi there,
More than 2 months ago, my Zero DAC dies. 
I have contacted Lawrence, he askmed me to send back the main board (it was under warranty).
It costed me 35 Euros signed from France 
Lawrence received it and told me that the DACship was dead.
He had to send it to the factory for repair`.
and since then, he tells me that it should be repeaired soon.
But nothing done, I'm still does not have it back.
Anybody has got a mainboard back repaired from Lawrence ?
Thanks

Sadly, I fear the €35 would likely have been put to better use by saving toward a new DAC...
Lawrence has a reputation for leaving people out to dry. Ah... you're not English, I presume... he has a reputation for ignoring problems and hoping they will go away.

actually i also have this small problem, but i am using pc, hence i can adjust the left and right balance to ensure both side are equal loudness.

I can't believe the Zero has gone down the poop drain. I was always extremely happy with my Zero as it has (and still does) serve me well. I'm in the market for a sub $200 DAC/amp that offers similar value. Does anyone have any suggestions? I've obviously heard of the Compass, but seeing as I'm buying this for my brother, I want to avoid spending $400 and ironically giving him a better headphone amp than the one I own.

do any of you know what's the peak voltage swing the ZERO can output?
@ freckling: at this price a joint dac+amp not DIY solution is the xonar ST, but your brother have to have a desktop computer with windows. i'd also like to have more good stand alone options below 200$...
