Well, I spent time talking with Nathan today and he was a pleasure to deal with. He listened patiently and did a great job explaining how the product works and what he thought would work best for me in my room.
He also talked about possible upgrade paths after I do my audition (he is very confident that I won't be returning the products).
To start with I am going with a Roompack + Seam Pack.
Will let everybody know how things go.
BTW, I am comparing the EighthNerve products to my existing room treatments (EchoBusters + Argent Audio Roomlens).
Regardless how the audition turns out, both Bill and Nathan are highly recommended and cool guys.
