Upgrade to dcs bartok.

You would get a much better sound if you got an Aurender N20 or N30 if you can stretch that far and use the Sim Audio for DAC/Pre until you can get a decent Pre-amp (Pass Labs?). Then if you're still searching upgrade the DAC (Musetec 005?).

Go and hear them all DCS does not sound good because it's expensive and a DAC cannot improve what it's fed.

I thought the p5 was a preamp.

You are right-meant S5.  Sorry

I had the DCS Bartok and loved it.  It Tidal MQA sounded like people playing in my living room.  I love the one box for Dac and streamer as well.
