I picked up a 20' Sony, PVM (Professional Video Monitor) CRT and some RGB Retrovision cables, recently. I did a comparison and wanted to share the results. Best picture I've ever gotten, easily. Better than any emulator I've played on as well. The comparison LCD is a Dell AIO.
Everyone is familiar with these. RCA or RF really doesn't do justice to how great the SNES and Genesis can look. Thankfully, both consoles output RGB natively without any mods.
Up until recently you had to use a scaler, like an Framemeister or X-RGB Mini, which are really expensive or get SCART cables to pull this off. I did a post on pixelpuck a few years ago before I took the site down about SCART & RGB on a Genesis. It was a big PITA and I couldn't get near this level of quality.
These Retrovision, RGB cables are pretty amazing, especially when combined with the RollsRoyce of gaming motors.

If you like to play on old hardware, I would definitely recommend getting a Sony PVM CRT and pair of Retrovision for your SNES or Genesis. The results speak for themselves.
There's going to be lot of CRT's at Waves but I will probably be lugging this guy to Toronto for KO94-4. Hopefully it can be put to good use.
