I likewise do not want to sound like a promoter, but have had a very similar experience to Dlcockrum's with SR, including dealing with Micheal at Vineyard who was very helpful. I ended up replacing a BPT 3.5+ and a full high-end Virtual Dynamics cabling and PC system. The improvements were very noticeable, and have taken my system up a few notches, at least. It has definitely been a fun journey for me as well.
