Why do people use tube amps

Default is linear.
The interesting options are pass band, stop band and SB attenuation.
Here you can go from a brickwall to a gentle slope.

How does the linear compare to EQHQv5 apo, objectively?....

Is upsampling not offering some alternate reality?

I believe linear is supposed to reproduce signals under Fs almost perfectly with some well understood artifacts that may be way below hearing limits? Or maybe we’re still treading around that limit

Got the resampler to work, pretty user friendly and the graphs are very useful. Still not sure if it's better than FPGA 2k/4k taps implementation. Caution: the ability to run Amanero at its full 384khz capacity may produce an overwhelming sense of power

My corrupted psychology tells me the sound is much much smoother. Perfection

Great, you did it. And yes, much smoother even when I didn't upsample at the beginning. Especially the high freq are far more natural to my ears.
And I am thinking about what music next

The good news for Soeren is that the bottleneck is not so much the hardware. OK, still a little

Uses 1-2% CPU. The smoothness is probably not imagined... and the highs are still there. I would prefer to see at least an attempt at a theoretical explanation before I settle on it though... This is certainly something nice to try for those of us using USB, not so perfect for the SPDIF folks....
