Interesting fact:
The plenue 1 has the same PCM1795A DAC, 2 x I/V OPA1612 opamps 1 x OPA1612 opamp for HO (compared to 2 for balanced) as the Plenue S. It uses the same processor but its underclocked in the plenue 1 due to heat so restricted to DSD128. The Plenue S processor runs at full speed and can do DSD256 but needs the large heatsink body to dissipate the heat. All the other plenues use the same processor too but eg Plenue L doesn't need a huge heatsink as DSD256 on the ESS9038pro is passed natively bit perfect (no level meters or jeteffects either) it also does on the AK4497 and the R2 Cirrus Logics. The reason these dont need a large heatsink is the cpu doesnt need to convert DSD to PCM. burr-brown PCM1792/1795 DACs can only play PCM (hence the model name) the cowon software converts all DSDs on the fly to PCM (this also allows level meters and jeteffects) and requiring more cpu power thus generating more heat.
Burr-Brown have seperate DAC models for native DSD playback. DSD1792/1795 etc.
