I actually haven’t heard Magnetar or Reavon. I read reviews in HiFi mags that didn’t tell me anything useful. I am going by user reviews. I came close once to buying a Magnetar so I had done a lot of reading.
My understanding is that Magnetar was formed by the engineers that had designed the Oppo players. The Magnetar GI looks identical to the Oppo UI.
In my case the DSD is output over HDMI into my Bryston DAC3 (which uses an AKM DAC chip). So the internal DAC is of secondary interest.
