Good to hear. I wonder what was up with those reports I read?
I think you're referring to one of my previous posts. Honestly, after thinking about it some more, I have to revise my input to say that I don't know what was up with the 661. In retrospect, perhaps I shouldn't have posted because I didn't fully diagnose what my own issue was. Since I was using the 661 as a bitbucket, I never needed to figure it out further.
Anyway, when I had the 661, I wanted to test how the unit sounded through the XLRs, so I set it up with my Oade preamps outputting to the XLRs. In this configuration, I was getting significant noise using the XLRs. Since I'd read previously that unbalanced inputs to the 661 was a no-go, I just made an assumption that was the problem and didn't diagnose any further. However, now that I'm thinking more about it, since I didn't do any diagnosis for myself, I don't know for sure if this is absolutely true...my previous statement was based on an assumption that what I'd read about the XLRs was actually true.
