I really like that 5 dollar amp you had listed earlier.I have 3 Q-sound amps in 3 Big Blue cabs. At one point in time, my 3rd Big Blue cab used a cheap TDA7297 amp until I was able to acquire a 3rd Q-sound amp PCB. During the time when I was using the TDA7297 amp, there was little difference at playing level volume. The only time when you could notice an appreciable difference in sound quality is during some attract mode screens. Otherwise, in-game sounds are subdued because the players are 3ft away from the speakers. Furthermore, in a home environment and not in an arcade operation, there is no need to turn up the volume to drown out the ambient sound of arcade machines nearby. The Q-sound amp is a very powerful amp, true. But understand that an amp alone is not going to get you superior audio. Particularly if you are using the speakers that can fit in an Astro City's speaker enclosure. It is like putting a a turbo charger on a 4-cylinder car.
So like @Solmin says, unless you are doing it for purity/preservation/restoration, which is why I obtained a 3rd Q-sound amp, there is no need to get setup with a Q-sound amp. What you are trying to achieve is stereo sound, an improvement over mono. Hence a modern day 12volt amp will work just fine.
Thank you very much. I really wonder how this stereo sound did work with seibu. And mvs because yes I saw the very same effect that it’s already too damned loud. Adding the line level converter and a amp seems like a first amp down and then up silly idea. But right now that is the only way I see here.The amp adds no benefit to the Q-Sound effect, the processing is all done on the CPS2 hardware itself.
Re MVS, it's already outputting an amplified signal so you don't want to run it through a second amp. If you do, you'll want to use a line level converter.
I have this one@hardyhell, that is the amp. They revise it frequently with new IC's. But same basic amp built around a family of the same IC's. Make sure you have on hand PCB feet to be able to mount it. You'll want to feed line level sound to any amp otherwise, you can easily blow your speakers and ear drums. Use a line output/level convertor to do that. Something like this for starters and you can work your way up from here.
