I went from a Cambridge transport to a PS Audio transport and finally a Jay's cdt2-mk3 transport.
Absolutely amazing amount of difference in sound performance and all with the same Gustard x26 pro dac.
Also of note, using the Jay's with I2S connection via a Tubulus Concentus cable, quite a step up from the coax connections I had with the Cambridge and PS Audio. Sorry Jasonborne, cables and transport matter, in my experience anyway.
