Can someone help me figure out if there's anything I would give up by replacing my Meridian G98DH and Sony Bluray BDP-S500 with the Oppo BDP-83 Bluray player modified with the 4X SPDIF Shawn Fogg board?

I am currently using the G98DH for CD, DVD, DVDA playback with HDMI connected to a Panasonic HDTV and 3 x digital coax main outputs with MHR Smart Link connected to my G68.

My Sony BDP-S500 provides Bluray playback and is connected to the G68 with a digital coax cable.

So, can I effectively replace my G98DH and Sony BDP-S500 and get the same (or better?) functionality with the modified Oppo BDP-83?

By the way, I have a 7.1 speaker set up with 2 X DSP5.5k, DSP5k Center, 2 X DSP5k rear, 2 X DSP33 sides. All speakers are 96/24.

Many thanks for helping me sort this out!
