Could someone explain what the different buffers numbers represent and what effect they have? And what are the adaptive settings doing, that is are they changing buffer size according to resolution?
Hi Wil,
You can access them as outlined on page 14 of the TAS Manual. The buffers allow you a degree of finetuning. Larger is generally more expansive/immersive with more bottom extension, smaller is tighter / more upfront. Somewhat similar to moving from tube amplifiers to class D. There is a limit to these depending on what your driver supports. Some DAC drivers only support 1 value in which case you're best off setting the buffers to Auto which follows your driver defaults. Most XMOS based interfaces allow values between 256 and 2048 for PCM and 8192 to 65536 for DSD. The Taiko USB driver allows PCM values from 32 to 8192 and DSD values from 2048 to 262144. Adaptive employs different values for different sampling rates.
There is a pattern emerging in general preference which is:
-XMOS based interfaces with the Taiko driver PCM:4096, DSD:8192
-XMOS based interfaces with vendor supplied drivers: PCM:Adaptive-1, DSD:8192
-Amanero based interfaces: PCM:2048, DSD:8192 OR PCM:Auto, DSD:Auto (likely depends on the firmware revision)
-Chord DAVE: PCM:256, DSD:8192
-AKdesign and other exotics appear to only work with Auto / Auto
