No. The VA4 Genesis Model 2 has a YM3438. Like with S-Video and Composite, I will not accept a Genesis with a YM3438. It MUST have a YM2612, it's the chip the Genesis had when it was first released. If the YM3438 sounded the same like the YM2612, I wouldn't care, but it doesn't, so any Genesis I have with a YM3438 sees very little use.
To really get the best Genesis Model 2, you have to take a VA2 or VA2.3, replace some resistors, relocate another, and replace a capacitor. Those are the only Genesis Model 2s I recommend now to those who can solder or know someone who can solder. Out of the box, yes, a VA4 Genesis Model 2 is best, but overall, a VA2/VA2.3 Genesis Model 2 with mods is what I consider as the best Genesis Model 2.
