GNSC PASI Units?

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...

Tabl10s, I did not notice a drop in volume. I had Bybee filters on everything when I bought the PASI. As I experimented with the system I found that it sounded more open with the Bybees removed. Just my personal opinion, I would definitely experiment if I had the PASI in addition to other inline filtration. Truth be told I was never overly impressed with the Bybees (deluxe balanced and deluxe speaker). They were very expensive and to my ears in my system their audio effect was minimal at best. The PASIs effect was much more noticable. The sale of the Bybees more than paid for the PASI.
