Bryston 14b3 or Bryston 4b3 amp. Use a great tube preamp with the Bryston and you would be surprised at how good it will sound. The crucial choice is the preamp because the Bryson's are pure, neutral power...solid and dependable. In other words, the preamp you chose will determine the quality of your audio output while the Bryston simply delivers it to your speaker choice.
Will an Amp change improve my system ?
My system is WiiM pro ( a great device for $149 !) and a Cambridge CXC V2 CD transport for digital input going into a Schiit Yggdrasil+ DAC going to a Schiit Freya+ preamp into a PS Audio S300 amp into Harbeth 30.2 XD speakers. I am considering replacing the S300 with one of the following: PASS XA-25, Coda S5.5, Benchmark AHB2, or tube Primaluna EVO 400, used Rogers EHF-100 or 200, used Luxman MQ 88uc. I like my current system and wonder if an amp change would improve it significantly ?
