I thought we could use a place to discuss the Theoretica Applied Physics BACCH products.

I have the hardware version, BACCH-SP adio. Mine has an EXCELLENT DAC inside it. It can also act as a Preamp with no degradation. Edgar is of the opinion that the Roon Server source isn’t that important. I understand his point of view but don’t share it. I use either a Pink Faun or a Grimm MU1 as a …

I read your experience very carefully… I think I will opt for the audiophile option. Since the only way to check the experience of the basic version is to log in to Tidal on the mac mini, and skip Aurender (which doesn’t make any sense). Based on Theoretica’s recommendation, I bought a 2018 Mac Min…

I would love to have the BACCH-SP, it must be wonderful!!! you are right about buying a version and doing all the queries. I will listen to Don Edgar :wink:

I’ve been following this with much interest as I also await delivery of my DSD Mk2. I have a large room where my audio resides, being an open plan lounge-dining-kitchen area. I listen in both the lounge and kitchen. I suspect the BACCH will be much better in the sweet spot of the lounge, and that…

It’s just very enjoyable (the BACCH Filter). I’m not ever certain it needs to be bypassed. For what it’s worth, I haven’t found a …

Thanks @aangen What puzzles me is that means Nuc > USB > DSD Mk2 will sound the same as Nuc > Mac (BACCH) > DSD Mk2 when the filtering in the latter is switched off. People are splitting hairs over the sound signature of elite USB cables and yet the second pathway, with a Mac computer between two …

this forum is a bad influence :joy:, of course I’ll move on. I appreciate the help on the subject. I’ll take a look at the thread you mentioned. Cheers

My kitchen and dining area is off the main listening area and forward of sweet spot by 20 feet and gets music through a six foot wide open door right of right channel. Having Bacch DSP engaged improves intelligibility of vocals, realness and live music sound of instruments. Tonality and timber and…

[image] Philip_Gan: I guess that brings up another question - is the sound quality poorer when out of the sweet spot of BACCH with it on, compared with no BACCH filtering? The sound quality is not poorer but to fully experience the immersive sound stage you need to be in the sweet spot (or di…
