Reviving this slightly aged thread. I did buy a DSJ and after 500 hours of burn-in I struggle to hear any significant difference between the DSJ and the DLIII. I’m surprised by this, given the many comments about how good the DSJ is. For reference my speakers are PSB Imagine T3 driven by a Pass XA-30.5 power amp, itself driven by a Pass XP-10 preamp. All cabling is Wireworld (Eclipse interconnect and speaker, Starlight digital coax). I’ve compared the DLIII and DSJ several ways;
(1) Both fed from the digital coaxial output of the Squeezebox Touch, i.e., NAS–power line Ethernet -->Squeezebox Touch–digital coax–>[DSJ or DLIII]–>Pass preamp.
(2) Both fed from the digital coaxial output of a Denon DCD1650AR CD player, i.e., DCD1650AR–digital coax–>[DSJ or DLIII]–>Pass preamp.
I’ve also compared the DSJ Bridge and digital coax inputs, i.e.,
(3) NAS – power line Ethernet --> DSJ Bridge Ethernet input–>Pass preamp
NAS – power line Ethernet --> Squeezebox Touch–digital coax–>DSJ coax input–>Pass preamp
With (3) there’s a small difference in favor of the Bridge input, but with (1) and (2) I struggle to detect the difference between the two DACs. I first made these comparisons at about 200 hours of DSJ break-in, and I’ve repeated them at about 500 hours of break-in. I’ve updated the DSJ firmware to Snowmass 2.01. And after 500 hours I don’t expect the DSJ to improve further.
Is the DLIII really as good as the DSJ or is something amiss?
