The HDAM is ordered separately anyway so no loss there...

Thanks...I'm thinking I might give the HDAM a shot. From reading this thread, it looks like someone with minimal technical skills & no soldering iron can still get it done, right?

What would be recommended (sun, earth, moon)? I bought mine around 10/08 from wsz...not sure if that tells you what chips are in it (I no longer have our correspondence). Sources are a Pioneer universal 563a & a Squeezebox Duet. 'phones are Grado 60s. Amp is an Onix SP3 (40 watt tube integrated) ->Vandersteen 1c.

Anyone have a spare?

Thanks.

it comes with a dual OPA627 into the DAC section, but for the headphone amp, I think I'll put 2 LT1364....

I've read that OPA627's sound better than LT1364, even in the head/amp section...

is it true ? do I have to put 2 dual OPA627 in the head/amp unit ?

The general consensus was that LT1364s were the best in the head-amp section. See the very first post for the results of Penchum's testing.

That is a good vendor. They'll send you the correct OPAs. They send you a standard instead of "upgraded" Zero.

I hope so

but the question is : WHO will pay the shipping costs for the mistake that HE made....?

I don't want to pay 30$ again to send back this wrong DAC version...

I would think you would just get the chips on/and the adpater. What else would you expect?

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.

Zero DAC with the HDAM, LT1364, and upgraded volume pot - eBay (item 230349545923 end time Jun-22-09 21:09:16 PDT)

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?
