PRS accomplished their goal with the HX/DA. They got primo and famous examples of a couple great amps used on classic albums by iconic guitarists, then duplicate those amps exactly. Done!
So, don't hate me for saying this... Now that those have been out a few years, IMHO, PRS should take exactly what's there, and another switchable gain stage so that you could still have exactly what you have now, or switch in another gain stage. They could call it the HX/DA/VH... if you get my drift... Some of the other boutique guys are doing plexi circuits but adding another gain stage, with very successful results. (RedPlate, etc). I think it's a logical next step and would be VERY popular!
As long as they keep making the standard HXDA as well, heck I'm all for it.
Yeah, I have a current HXDA, but when I do the "Older Than Dirt" Wooly Mammoth & The Cave Men World Tour, I'll probably want to have a backup of the amp I have.
