Wow, your set ups look awesome! I really admire candy cabs - I hope someday I can get some.
My set up isn't anything fancy. Two Big Blues - the left one is authentic, straight from the factories at Capcom. It is a Hyper Fighting Cab and nothing else. No mods - I have updated the sticks/buttons to IL, as the Happ ones weren't so good. I spent a good deal of money hiring a guy who "fixed" the aging monitor - it looks as good as it can at this stage. Has significant Phosphorous burn and warping, along with a significant bleed in / sharpness issue. I have the screen squished to a compressed widescreen mode to offset these issues, as inaccurate as it is.
My faux Big Blue has Q-sound installed with an HF board hard-mounted and a CPS2 switch. I have quick d-connectors for the Q-sound/CPS1 audio, CPS1/CPS2 Kick harness changeouts. Along with some boards, I have a Darfksoft mod installed. The Sticks and buttons are IL, which feel nice. What gives this away as being in-authentic is the plexi CP and the cutaway being deep, resulting in the truncated IL Stick. Works for me and gives it a faux-sanwa vibe.
I've had a lot of good sessions with friends on these cabs. I have extended it to locals, but no luck in getting anyone interested in playing a a US setup, sadly.
And I had to highlight my cat Doom, who loves hanging out with us when we play. 😃
