GNSC is at 651-762-8333,Rja is right in that Steve can do amazing things ( he did my MFA D75 and took it to a level that is shocking for a 15 year old amp).I think that if you can swing a new or used 861, you will have a front end for a long time to come.It should be modded for sure , otherwise the wadia sound a bit sterile in comparison. I think Steve's work is truly first class and sonically one of the best moders outhere.
