Great plugin

Great software. The effect is simply stunning with binaural recordings, great with live or live-in-the-studio recordings and sometimes not so great with multitrack pop records, but the plugin is a must have for any serious audiophile.

I really love the idea of crosstalk cancellation and I really see the potential!

But I’m waiting month’s now for a fix for Audirvana UPnP..

Ubacch Plug-in is transformative

Listening with the Ubacch plug-in has had a transformative effect on my system. Without it, music sounds two dimensional; with it; music sounds three dimensional, with performers arrayed in a realistic performance space.
I began using the plug in with both JRiver 31 and Audirvana streaming to my Bricasti M3 dac over Upnp/DLNA, but the filter did not seem to work properly in this kind of setup (pink noise could not be generated and the slider seemed to have no effect on the sound). Switching to a direct connection to the dac with USB solved the problem. I could not adjust the filter to produce an image wider than the speaker's location but the improvements in soundstage width and the sizing of instruments is dramatic.
For me, the investment in the Ubacch filter is well worth it.

Interesting result without any measurement

This plugin is doing a very good job and the result on the sound stage is amazing with many relief and precision.
The result is very interesting without any measurement.
I’m mainly using it on my only stereo home video configuration because the sound is more immersive and impressive and U-BACCH VST3 plugin has a very low latency used in JRiver Media Center DSP Studio on Windows 11.
For my audiophile system I’m using a more elaborate solution based on measurements at the price of more latency.
