Audio Research PH3 Upgrades


Was interested if anyone knows of a company that is doing upgrades for the AR PH3 phono stage. The upgrade to the PH3SE is quite expensive from AR. If so does anyone have any feedback on the improvement? How the upgrade may compare to the PH3SE?

Hello, Great Northern Sound is the company to go to. Steve Huntley owns it and is great to deal with.
