Quoted from Reznnate:Quality of sound is largely dependent on the audio mix and speakers. If you're merely adding to upgrade the existing audio/samples, the cost is prohibitive IMHO.
This video was clearly recorded with an inexpensive mic, so the actual game audio sounds better.
I personally prefer this mix because it changes the vibe of the game.
I recorded the video with my phone, and the pinball is still on the original speakers, I bought the visaton speakers and the quality will certainly be much better. As for the mix, it's great, the game is much better.
