I believe that there are former EAD engineers in Fairfield Iowa that can upgrade your EAD unit. The name and contact info escapes me, but Google is worth a try.

I know of Noble Electronics, and there's an excellent engineer in France or Belgium (sorry Christophe - I can't remember which at the moment!)
The EAD certainly can be upgraded, but the cost of doing so really isn't far short of what the AA DAC would cost me.
I am torn. Loyalty to a faithful friend, or investigating pastures new?
OK... Short listing in a hurry now as the EAD will be on it's way as soon as the festive season is over.
The Ayre QB-9 has a significant advantage in that it has a USB input. However, my heart is still saying the AA DAC1 Mk4 is the solution I want, probably with a John Kenny modified Hiface M2.
Any other suggestions? Ballpark budget is a maximum of $2500; previously loved equipment preferred!
I haven't heard Mk4, but I used to own AA DAC1 Mk3. Now I own Ayre QB-9. QB-9 is the best digital I have heard in my system. Also keep in mind that not all USB DACs are the same. In addition to the superior jitter control, Ayre also incorporates time domain coherent MP filter which makes Ayre unique and superior than its competitors.
On the subject of DACs, i need some help and i was wondering if someone experienced here can help... I have a Wadia CD Transport WT 2000 and a Wadia 2000 digital decoding computer (DAC) that sits nicely with it. Of late, I have had a problem with the Wadia DAC. Under the Command function, when the button is pressed, it moves from "standby" mode to the "initializing" mode, and thence to the "operational" mode. All good so far, but subsequently (within 30 minutes), the "red light" moves back to the "initializing mode" and as such i cant listen to any music.
Has anyone experienced this problem before or know anyone who might have ? Can anyone help me / advise where I can go to get this fixed. I live in London...
