Trey, I was reading a bit about the DL Three.
I notice the chassis of this unit is different than later PS Audio gear.
Is it essentially the design the same, though?

I found this last night while reading about this unit. I was a bit intrigued about by this information...

The output stage is the key
Once the sample rate has been converted, it is sent to the TI PCM1798 balanced DAC and its output is fed into our unique output stage.

DAC’s convert the digital signal into current. Unfortunately, to play music through our systems, we need voltage. So the first job of the all important output stage is to convert the current output of the DAC to a voltage, then amplify it so our preamplifier can play it back through the power amp.

99% of every DAC on the planet uses an op-amp to convert the output of the DAC to a voltage. We learned years ago that this is the worst thing you can do for the sound, because op-amps all have two major problems when used for this function: feedback and speed issues.

Without getting too technical, the greatest opportunity for a bright and edgy “digital” sound is caused by op-amp based current to voltage converters (IV converters) because the high speed of the DAC’s output causes transient or slewing induced distortion in the op-amps (SID). SID is a combination of feedback and transient response issues that some exotic high-speed op amps can come close to handling, but all have a problem with it.

PS Audio’s engineers avoid the SID harshness by eliminating the feedback of the IV stage. We do this by a unique single transistor IV converter with no feedback. Speed issues and SID issues are completely eliminated with this technique.

I believe so but I don't want to mislead anyone so I can't say for sure
