Yes, component is much better than composite. As for the sound issue, you needn't route the sound through the SCART. Just take the sound from the back of the TurboGrafx-16 CD-ROM Interface Unit and send it straight to the high-powered stereo receiver with floor-standing speakers that are as tall as you (at least).
IMO "crappy" is needing five damn RCA connectors just for component and sound. Its f*cking ridiculous.
Why? It's not like you must constantly plug and unplug them. Once they are plugged in, you're good to go. If your life is so hectic that you can't be bothered to spend a few extra seconds plugging in some cables, then perhaps it's time to give videogames up altogether.
When you have one component input on your massive ass CRT, and 2+ systems using said component inputs, this becomes a f*cking chore.
Climbing around back isnt "a few extra seconds"
Its more like a few minutes, swearing, hoping you dont knock shit over, fumbling around with cords hoping you did it right, more swearing, dropping stuff, more swearing, praying the TV doesnt fall, realizing you just plugged the green and blue in the wrong holes because its dark back there, swearing, finally connecting it all, and then finally playing the f*cker.
Yeah you could get a switch box, but that shit will look awful. 15 RCA doodads shoved into a box, with cables running out the back into your TV!? Yikes. There goes your stuff looking tidy.
