dCS Bartok 2.0

[BlurRhino]

For Bartok users, do yourself a favour and update to the new 2.0 firmware now. Wow.

Haha the magic of dCS.
Part of the improvement come from updating the mapping algorithm that set the DAC operating frequency is someting I totally don't understand.
The update also change the upsampling/oversampling sequence, and filter roll off.
Don't know if any others DAC maker capable of doing this sort of optimization.

It gives users tons of settings to choose from. You can play with the different settings to make different kind of cds, digital files sound to your liking.

Have not play with the new filters yet but additional maps are really good - I think ppl who complain that Bartok sounds “polite” will be happy now.

I definitely recommending reading the Ring DAC White paper, it explain how the Ring DAC works quite clearly; https://dcsaudio.com/assets/dCS-Ring-DAC-Explained.pdf

The crux of the 2.0 release is to (1) double the frequency of the internal sample rate to 6MS/s (mega samples per second) from the previous 3MS/s, and (2) to tweak to the pseudo-random algorithm that selects each of the 48 resistor within the unitary-weighted analog conversion stage.

The results is that noise gets shaped even further away from the audio frequencies, while audibly lowering distortion.  Mapper 1 specifically really show how lowering the distortion allows so much more micro-details to emerge. 

By the way, there’s no change to the sequence of upsampling (on Bartok or Rossini, with 2.0), just the addition of DXD2.
