Mods for ARC preamp / amp


There's a company called Great Northern Sound advertising on Audiogon saying they can do some pretty amazing mods on ARC gear. Has anyone out there used them? Were you satisfied by their work? I have an Arc ref 3 / ref 110, before I consider handing them over for a mod, would really like to hear from all of you. Thanks.

Hi Erik...I have similar setup with CD7 as well. GNSC does not do mods for the Ref 110 nor any of ARC's digital products. So the only product eligible for modding is your Ref 3. I contacted them a few yrs ago and at the time decided to wait. By the way they also mod Wadia products so you may want to enquire about their mods there. I am interested to see what feedback you get. Also, how do you like the combo of the Ref 110 with the Elipsas? Did you always have this combo or did you switch over to the Elipsas with the ARC gear? Is the Ref 110 sufficient to drive the speakers? Thx
I mean an Oppo.. yeah easy to upgrade the audio. A product like the Ref 3 would be pretty tough to mod and have it worth a damn. AND Audio Research would not later be willing to fix it. Unless they put all the stock stuff back. So then you got no more factory support. And One of the GREAT things about Audio Research products is they will fix them nearly forever. (except the CD players.. which was a parts problem) So your modded Ref 3 resale goes out the window.
If you REALLY need to upgrade your Ref 3... BUY a new Ref 5.
I own several Audio Research products.
Do an internet search on GNSC modifications. They are not new at this and have been doing it for a long time. Steve also has a history with ARC. I believe that there are some reviews of their mods on HiFi+ magazine. I have not owned thier products but have heard them in others systems and was impressed.
