So far, the effect is pretty remarkable. Beyond the spatial influence, the overall sound becomes much more lush, perhaps it's the way that sound gets layered in space.

I also completely stop thinking about the sweet spot, it's just always in the right place.

I'm very impressed so far.
Thanks for sharing! Still waiting for the delivery of BACCH4Mac and great to know you are impressed apart from the bass issues

I would like to announce on this forum that Theoretica just released BACCH-dSP 8.0 (the application at the heart of the BACCH4Mac product) which has many new features and improvements. Among the improvements that are relevant to people on this forum is the new Bass Correction feature that fully restores the phase information to the low-frequency (LF) part of the audio signal after it goes through a BACCH filter. Previous versions of BACCH-dSP relied on minimum phase filters to handle the LF part of the crossover, which caused the deep bass (below 90 Hz) through the BACCH filter to sometimes have a different level than that when the filter is bypassed. This is no longer the case with the new Bass Correction feature, which provides a bit-perfect match between the LF component of the audio going through a BACCH bin and that going through the Bypass bin.

While the Mono Correction feature (first added in v 7.0) fixed most bass issues, the new Bass Correction feature of 8.0 completely fixes bass reproduction down to the lowest frequencies.

This Bass Correction feature will also be part of the next firmware upgrade for the BACCH-SP processor, which is planned for release in May.

Regards,
Buddy @ Theoretica

Is the 8.0 update accessible to SP hardware users, or only the 4mac units? Will I need to wait for the firmware update?

Thanks!

BACCH-dSP is the standalone Mac application at the heart of Theoretica's BACCH4Mac product. The BACCH-SP processor does not run BACCH-dSP. It runs completely different software but uses many of the same algorithms as those in BACCH-dSP. The new Bass Correction feature is presently available only in BACCH-dSP 8.0 but will soon be available in May through a planned firmware update for the BACCH-SP processor. In fact, the feature has already been coded and is presently being thoroughly tested on the BACCH-SP before the release of the firmware upgrade. All BACCH-SP owners will get notification (as usual) when the firmware upgrade is ready.
Regards,
Buddy

Thanks for the reply! I was not aware of how different the two software pieces were, between the SP and dsp units.

I look forward to installing and testing this weekend. Will post my thoughts here.

Checking in. Has anyone with the 4mac version played with the latest update?
I have a bit but have been busy with work and family obligations. It sounds superb, and the automatic sample rate syncing is a welcome addition.

Slightly off topic, did you get the latest 8c update? They pushed it to me today.

When I powered down my system, it reset some of my dsp settings. Fixed now.
