Theoretica Applied Physics BACCH

,

Edgar,

As an early adopter I am appreciative of this announcement. “ BACCH-ORC will be available for $1000 as an optional module of BACCH-dSP 14 (Audiophile Edition and above), the application at the heart of Theoretica’s BACCH4Mac products, to be released in the second half of January 2024. Owners of a licensed copy of BACCH-dSP with a valid software update service plan on the date of the release will get a perpetual license for the BACCH-ORC module at no cost, in appreciation of their early adoption of BACCH4Mac.

Also reviewing the material it appears there is a boost user selectable dial but it is optimized for 6dB max and the cutoff frequencies are 20Hz-22KHz. By cutoff frequencies does it mean it is a brick wall filter no lower or higher frequencies can pass through without equalization or just that it will not attenuate or boost above or below the 20-22kHz cutoffs? I am hoping those of us with big driver and huge cabinet speakers and kilowatt plus amplifiers capable of producing bass down to 16Hz or lower we still get to enjoy our seat of the pants organ or synthesizer music that goes that low.

Thanks

Wow!

Is this available as a stand alone solution (for folks who don’t own any of your related products or software)?

Apologies if this is addressed on the linked-to website…

Best of luck to you with the roll out.

As Flounder from Animal House would say…

“Oh Boy is This Great”

We can’t wait to hear BACCH-ORC in our home!

A review of the BACCH4Mac Stereo Purifier by TAS.

isn’t most of what we listen too engineered, ie performer’s microphones are represented on a mixer board…then the engineer places them, probably routinely, in a position unrelated to actual performer position for reasons of personal preference, training, listener expectations, or marketing

eg, a piano may be stage left during performance but engineered to be played in the center, or even the on the right

eg, bass and vocals and even drums are often, even typically, mostly centered on stage

microphone placement is often for reasons other than accurate spacial presentation; sometimes a performer may be in an entirely different room/sound booth from others

Tom Martin notes a few times that engineers place instruments

nevertheless, look forward to auditioning BAACH and assume it is an advance

I think that I might not be as critical as some of the members on these forums. The reviewer did mention how on several recordings, the placement of the performers was incorrect due to microphone placement during the recording. I am assuming the recording Engineers were expecting the listener to be using a standard stereo system. So the performers would end up in front, rather to the side or even slightly behind the listener. Nothing is ever perfect. So far I have not had to turn off the BACCH4Mac filter during my listen sessions. Enjoy any future auditions!

He provides realistic and accurate depictions of the Album presentations. These I have heard in my bacch4mac.





I wish to sample these.

If Paul and Edgar got together and produced an AirLens that had BACCH included it would sell like hot cakes… just saying!

Exactly, I think B4M coupled to a good DDC will elevate the performance again!

But I’m not sure if B4M software will recognise a DDC as ‘dac output’.

My B4MAC sending USB to Matrix DDC with a AQ Dragon HDMi to MK2 i2s1 sounded nice. But caused BACCH4Mac to hang up every few days. I became an annoying service call to Edgar. Who surmised the Marix2 clock changes were the culprit. Once I pulled the Matrix2. The issued disapeared. I resolved SQ changes by purchasing a SOTA Inakustik Pure Silver Air 2404 cable. Edgar was of course right and my sound improvement went a huge leap forward as did stability. While making calls to Edgar not needed.

Rats. I may have a situation in the future where I was thinking of using a Matrix between the B4M and a DAC. With your new information I guess I can forget about that.

The Dragin can be used teed a HT like i do. Or dunp you tube to a HTProcessor and to preamp twith passthrough to get XTC on Videos.

The mk2 is sounding exceptionally good with massive final release. But so would Baldy’s Vivaldi sound good

Rossini APEX. Vivaldi is one step above my pay grade. :grin:

I think the new Audio GD di24HE will be the best DDC for 2024/2025. I would bet on that bad boy

That is a very impressive looking device! Unfortunately, I do not believe any such device will work well with the Bacch4Mac. This does not in any suggest that the fault lies with the DDC. The DDC is most likely wonderful.
