Which CD\SACD?

I have the Oppo 105. Nice but not in the high end league. Try Ayon Cd 07 new or used Ayon CD5

"I’ve never heard the Oppo, modded or unmodded, described as "rich"."

My modded Oppo 103 was rich sounding. There, now you’ve heard it. Is it possible my Oppo sounded rich because it was the most extensively modded Oppo on the planet? Maybe.

geoffkait, who did the work on your Oppo 103 and what mods were done? 

sort of on point, but have any oppo 103 owners notice that the volume level thru its analogue outs is significantly lower than thru its digital outs?

The first and second round of mods were done by Ric Schulz of EVS and included analog and digital mods, the Audio Magic Pulse Gen ZX box, high speed clock, Oppo Mods Linear PS, the one with massive toroidal transformer, with upgraded capacitors. The third round of mods were done by yours truly and included one of my spring-based ceramic tile vibration iso stands, complete double mu metal wrapping of toroidal transformer, cork isolation for circuit boards, WA Quantum Chips galore, constrained layer damping for toroidal transformer, Mpingo discs for CD transport compartment, Marigo VTS dots for most capacitors, replaced Oppo cover with clear Lexan, Codename Turquoise scattered laser light (visible red spectrum) treatment for CD tray, Dark Matter invisible light absorber for CD tray, mu metal/copper/3M AB5100s anti RFI treatment for all ribbon connectors, and quite a few PWB tweaks as well, you know, foils, Red X Pen, Magnadiscs, that sort of thing.
