Can you not go into a shop selling K+K boxes with your Baggs, and try that, and a K+K box, if you are worried?
Or, you could put the money otherwise spent on a quite probably not needed new DI, towards having a killer amp like an AER, that sounds great, and has a balanced XLR out to hook up to a PA when needed.
One final thought on acoustic guitar pickups, Taylors and Martins included: They often have a Huge Amount of HF information, and anything that dulls that a tad may well be a good thing! The times I have to dial HF off such signals are legion, in order not to have people wince at the 'bag-of-nails' sounds ... let alone have the guitar sound nice or sit well in a mix!
