From someone who has owned an entry level project, Original VPI Scout
Currently I have a VPI Prime and a 1200mk5
I would lean towards keeping the KAB 1200. Reasons is simply money. You will be looking at a Prime used to have something maybe a little bit better or just a slightly different flavor.
My Prime and stock MK5 are pretty close. The Prime has better left to right Imaging and soundstage (not a huge difference). A smoother sound which you appreciate in longer listening sessions. It has a bit more round/fat bass as compared to the 1200. It has maybe a touch better resolution. Depth seems similar in my setup.
Saying all this it could just be the cart differences as I have not done apples to apples comparison. With all the KAB mods I could see Bill Stevenson opinions being pretty accurate.
As I learn more about this hobby I realize at a certain point you have to devote longs listening sessions to discover if something is really an improvement. Stuff at these 4k price points sound more alike than different. The small differences are what we are paying for and choosing. To many these subtleties are worth it, to some they are not your choice.
