I would like to give another input on this new firmware update.
To tweak the DAC to your system or personal preference, we have the functions of NOS/OS and sharp/slow filter on OS. This is done by simply pressing some buttons.
Now Denafrips has given us another tweak for free, the new FPGA firmware, the root of the existing NOS/OS and filters tweaks.
On the Chord TT2, the bespoke FPGA DAC, it offers 4 programming filters:
FIL1 – Incisive neutral: the default, filtering characteristic; the absolute reference.
FIL2 – Incisive neutral with HF roll-off:
FIL3 – Warm: a secondary filtering, a subtle warming tonality.
FIL4 – Warm with HF roll-off:
Therefore, the new firmware update maybe be an upgrade to one but may not be to the other. It is just like NOS/OS and Sharp/Slow filters. It all depends on your system and personal preference. However, I believe Denafrips and Alvin think it is an upgrade to the DAC. And to me, it is a major upgrade.
