Hi there.

I am looking for a feasible solution since years.

This was one reason why I started my Linux journey.

I still consider Brutefir&Acourate filters the top of the top in terms
of filter and sound quality.

My challenges:

1. I havn't seen a multichannel solution, which delivers better sound quality (in terms of microdetails and harmonics ) then my stereo setup. (my fullrange speaker runs without any passive filtering btw.!)

Multichannel soundcards usually come with poor outputstages (opamps)
and PS.
I am also not willing to spent +4k for a commercial multichannel DAC. ( assuming that these might be able to do a better job)


2. If you follow the "CICS logic", running heavy filter processing will cause sound-degradation on the PC. ( If decoding flacs makes a difference already - what do you think would large filter processing do?)

On the other hand I don't think that any HW based filter can achieve the result of the PC based filtering ( with all its flexibility)

3. And not only the processing might cause problems, it is also the filtering itself. No filter is lossless. You will gain time and phase linearity and also a better in-room response - on a first glance this will be breathtaking. Stagewidth & depth, in-room transient response, seperation - just great. You can't beat that with any 2 channel passive setup.

On the other side there is a big chance that you loose micro details/harmonics (the soul of music) - at least that's my experience.

What keeps me sitting in front of the speakers is the transported "soul"
of music. Not the sound effects.

Don't forget to think about what's required to process different samplerates.

4. You need to do some "measuring" and a pretty good understanding of what you're doing. Not many people are able to do that. (And don't have the equipment to do so.)

5. Multichannel amps, cabling, mains supply all this gets really expensive if you want to put it on to a highest-end stereo system level.
Without knowing what you'll end up with - this could mean to burn a lot of money.

Will it be worth all the effort and risk? I guess nobody can answer that.

Good luck.

Cheers
