Remember, the GFP-750 is Adcom's cost-cutting iteration of a Nelson Pass design they licensed. If you want to improve it you'd be far better off selling it for $800 and buying the real thing: a used Aleph P (with remote) for well under $2k!
Think about it. I even queried Nelson about the GFP unit, and he said he had no idea how well they pulled it off.
OTOH if you use the GFP passively, it's probably worth keeping. If you use it actively, I'd try the Aleph P. It's build quality, transparency, ultra-quietness, and 3D staging are quite remarkable...and that heavy remote oozes ergonomic
luxury! Good luck. Ern
