Sonic Frontiers sfcd1 or Monarchy dac33/dip classi

My current digital system has Nak cd4 as a transport, Monarchy dac33/dip classic. Would the Sonic Frontiers sfcd1 be a significant upgrade? Any other players/transpors that would be recommended instead of Sonic Fronties? Amps are Adcom 565 mono blocks and James Audio s103 speakers. I would like to stay at or under what the sfcd1 would cost if I can find one.
