@Rob Watts
As far as I have understood, we have two couple of `option` filters: 256FS FIR ones (white/green) and 16FS IIR ones (red/orange).
What is still remaining unclear in my mind is where are they acting or applied in the chain WTA1->Crossfeed IIR->WTA2->Lin.Interpolation 2048FS->LPF->LPF->Noise Shaping?
I mean if we apply 16FS options is WTA2 (16FS to 256FS) bypassed ?
Regards.That's it exactly. The linear interpolation is either 256FS>2048FS (white/green) or 16Fs>2048FS (orange/red). To complete the picture, the HF filter on (green or red) is set by changing each of the low pass filter (LPF) time constant from 0.7 uS (227 kHz) to 2.8 uS (57 kHz).
OK. My understanding was that the white vs green made no difference in 44.1k or maybe even 48k. But it trimmed off some hf noise in 88.2 and 96 and above. Same with the orange vs red. Maybe @Rob Watts might say who's correct? I'm not concerned about the orange/red choices, as I bought the H2 to sound its best.
Not picking an arguement; it's just what I understand from all the info.For 99.9% of the time I just run with green. But I guess if my HP were way too bright then it would for sure be red...
