I would sell the Peachtree and the Paradigm speakers.
I would replace them with a high quality integrated ss amp, a Bifrost DAC and Magnepan 1.7 speakers or Vandersteen 2CE Sigs. I would keep the Vandy sub and crossover.
The 1.7's would really sound great with Jazz. But the 2CE's would match up with the sub very well and can be driven more easily. Also good wit jazz.
