GNSC PASI Units?


Have any of you had personal experience with Great Northern Sound's PASI devices?

I have been using one for about 2 years. Running balanced in and out. I like what it does, eliminating some digital nasties before they get to the preamp or amp. A little pricey perhaps, try a B-stock with minor cosmetic defect for $ savings.
Have been using for 2 years as well. I second Rja's impression. Talk to them, they may offer you a B-stock. In my case, nasty hum from tube amp is gone as well.

Did you find the overall volume lowered? I have the Ortho spectrum AR2000 which is similar but i've never used my PASI. I wonder if i should try both together...
