DSP filters are becoming better at reproducing tube amps.
I am sure that lots of people who already invested a lot of time, money, and energy into tube ecosystem will not settle with tube DSP filters.
But, free open-source DSP filters can perhaps stand in the place of tube amps for casual music listeners who are not fussy about particular details.
This is great for miniaturization of devices. One can just enable tube effect in smartphone or computer.
What do you think? Are tube DSP filters good enough for casual listeners?
