Digital enhancement

These from Kevalin audio remove distortions and add clarity  , but after seeing the cost ,I said just buy into a much higher quality dac with excellent filtering and FPGA  ,buffering , and filtering , like the top Denafrips 12 th anniversary Terminator   dacs, or Holosprings May dacs  , dacs that beat dacs at 2x their $5k+ price point .

they May work but waaay to much $$ their top effort almost $5 k  


The introductory price is $1000, to me, that's a lot to spend for that tweak. I'd rather spend more and buy a Puritan Audio PSM 156 power purifier.

The BACCH technology from Theoretica seems very interesting and effective, and the base system is under $1000. 

I think if you listen music with digital format,lossless or cd they will sound better with a simple matter too much tweaks affect the sound,or maybe some audiophiles use too much tweaks in the music systems has one the only condition, audiophilia nervosa.

Can anyone here write a coherent sentence? It really does impact how an argument will impact readers. 

I am admittedly very confused. I actually paid close attention to Bacch-SP for a short while but could not get a good sense out of whether the processor/dac is doing something different or better out of recordings that are already great in soundstage and image. For example, comparing (with good headphone is recommended) this demonstration (by the inventor/developer) with the original recordings done in 1992 what are your thoughts? I understood the quality of on-site recording might downgrade the quality of sound from the processor but if the original recording has been great in SS, image, separation etc. what do I need additional processor for. Does the processor take a so-so recording, analyze it and apply 3D effect to it? I wish someone that has actual experience with the processor could shed some light,

the biggest digital enhancement i've ever heard [aside from dsp room correction] was CEDAR. elimination of impulsive disturbances and broadband noise goes a long way towards enhancing intelligibility and enjoyment of phonograph-based music recordings. 

Have no clue what Kelavin is about … even after a Google search.  If you want to improve your digital sound you need to attack jitter first and then EM noise in your system.  It’s not as straight forward as adding a new more expensive DAC
