the pre-outs on the G4 that comes with RCA outs probably isn't going to be audiophile quality.you would be better off going with an aftermarket sound card.I say this from an audiophile stand point. most people probably wouldn't notice the difference.
right... im looking to compete in USACI SQ (like the pm i sent you) and i have 2 rockford fosgate 3sixty.2 processors on the way but it doesnt have any optical inputs. I dont know if i should just use the stock sound card because of the line level inputs or just go with the roadie or what not. (the 3sixty.2 is a 5v line driver too) but i dont want to loose quality.
I almost want to just build my own unit just because of the lack of rca's on the G4.... but im concerned if i can even would do it (although i would consult my friend that owns a stereo shop and repairs amps so he could help out alot)
At this point all i want is something that has a hard drive and can play mp3's/ music videos, dual layer dvds, 5.1 dvd audio discs and can give me a good quality 5.1 signal. All the rest is nice but other then those things i dont care if it has it or not.
From what I have read on other forums, there is not currently any brand of amplifier that uses optical input that does not rely on the same brand of head unit to work. The G4 is a head unit replacement so these amp options don't work well. Please inform me if I am wrong. I would like to go this route.
With a high level to low level converter, you would definitely lose noticeable sound quality assuming you are running quality speakers. There are amps that attempt to "fix" the high to low conversion by running the signal through a sound processor equalization curve like the RF 360. I really don't want to go this route.
I started a thread a while back where we were looking for optical in amplifiers. They simply don't exist.

My amp has optical input and it works great, had it a couple years.... it's a Pheonix Gold R5.1 Mobile Theatre.
