Simaudio I-5 LE and Benchmark or Bel Canto system

Moving from tube seps to simplify system. I have Tyler Acoustics Linbrook Monitors (91 db).

Should I go with a used Simaudio I-5 LE with a Benchmark Dac 1 (I already own this dac) or should I sell the dac and go with Bel Canto S300 and Bel Canto Dac 3. Both options would cost about the same, just completely different animals.

I enjoy jazz/acoustic/rock you name it.
