At the moment, two consoles at a time: one on RF (Famicom), the other on composite (Dreamcast). Personally, I never understood the RGB snob mentality when in most cases it's not really an issue since practically all TVs in use have comb filters. Lots of people also have expensive HDTVs calibrated so that real life looks like The Simpsons. Maybe many people just don't care to be enlightened? Also your definition of a decent TV and sound setup is certainly not everyone else's. For example, it's not possible for me to purchase my idea of a decent setup in America without tracking down expensive used/discontinued or professional equipment since the stuff I can buy in a store doesn't cut it for me. Until I can get a >13" RGB display, I'll stick with my composite TV instead of wasting money/time on a shit LCD/DLP that will be "owned" next year by OLED.
i have a 17" or so crt, with everything s-video or component going through an old pelican system selector pro, composite through an even older pelican switcher (hey, av famicom only does composite out of the box, don't look at me like that), and all the sound run through an onkyo reciever that a friend at work gave me for free. took a while to get everything and set up the cables, but i can play all my consoles with a few buttons and no longer have to go spelunking behind the tv for fifteen minutes whenever i want something changed. i envy you rgb guys though, all this scart stuff is gibberish to me. i've never noticed noise from the video switchers, but then again i've never really done any hard tests on it either. i guess if i knew a damn thing about electronics i could make some sense of this beast of a writeup.
The biggest problem is that the greater majority of low-end LCD TVs suck at upscaling your 525/625 signals into their native resolution (usually 720 or 1080 lines, or some weird resolution for some). And thus, it might shockingly look better on their supposed 'crappy' TV. Or, they've wasted too much money on their consoles and games.
geez no need to get all defensive, quoting prototype display media as "owning" existing media is ridiculous, its like refusing to buy an xbox360 because playstation 4 is gonna kick its ass anyways... and what, you lost all faith in SEED TVs already? :110: and fyi you can get fantastic new 32" tube TVs for practically nothing these days (if you dont like LCD & etc TVs)..
It's nothing like that because (and I think you'd agree) old TVs are considered dispensable while old consoles are not. OLED has already established itself as the LCD killer. In many ways it's quality is even better than CRT. I just had to share that I find it ridiculous that people shortsightedly adopt inferior new equipment similarly how you find it ridiculous that people still use old equipment. I have no idea what a SEED TV is, or really care, I know that OLED is the next CRT and will be here to stay as far as I'm concerned. Please define what makes a tube "fantastic" and how much you consider "practically nothing". Maybe you can find one that meets your specifications but I certainly can't find one that meets mine.
Well, if using a CRT TV for retro consoles, using an RGB cable compared to a composite makes a world of difference. When I made an RGB SCART cable for my Mega Drive I couldn't beleive how amazing it all looked, the same with the Dreamcast too. I can't use composite anymore, the colour bleed is awful.
