I was already in the process of turning from ribbon / planner speaker systems and a very details up front sounding system (I called “reference”)… to more natural musical sounding system. So ten years ago I had: ARC preamp and Phono stage, Pass x350 amp, Sim Moon DAC + external power supply and Sonus Faber Olympica speakers.
With this in place… indicating to me that i was the right path forward I swapped or upgraded all components to Audio Research Reference. With that incredible DAC in place… upgraded my streamer several times from a MacBook to the flagship Aurender and speakers to Sonus Faber Amati Traditional and upgraded my turntable from VPI to Linn. By an order of magnitude the biggest sound quality improvement I made in the last 50 years.
