Have question as well

I don't have a Taylor yet, but I'm working on it. I'm looking for info on the Fishman Prefix Stereo Blender system Taylor puts on their 5XX series and above. Does the mic really improve the sound quality when added to the piezo sound? What does the mic sound like by itself? Is good sounding direct recording possible with this system or not?And what a cheap headphones need to get?

Thanks!
