Hi soix...
I've had the Bacch Lab Plug-in download since last August. Do a search for the plug-in. I'm Windows based here in Maine.
Sadly, the price has been bumped up to a serious price for many now. It was under $300 last summer, doable for many music lovers having more moderate systems. I'm hoping popularity or competition will pull the price back to a more universal reach.
I'm running Windows 10 with the Foobar Music Player. Mike, my skillful Music Computer Tech, onboards the technical stuff for me, remotely. I'm age 78 (next week) and we collaborate nicely with finely tuned DSP, to a 100th of a decibel. Mike has longtime, deep experience, enough to have earlier applied crosstalk removal with results similar to the BACCH. He defined my interest in the BACCH as a "no-brainer" decision.
Here in my small-dedicated sound studio, the BACCH experience has been revelatory. As a highly impassioned music lover now having experience with the BACCH over many sweet-spot hours, I would not be without it. I find more minimalist, purely miked recordings respond best, large to small, from Mahler to solo vocals and instruments. I posted some early findings in our GoN Forum found in my history. Purity of tone "timber" is my most vital chase in recreated sound, where the BACCH continues to impress most, followed closely by a larger, more holographic, yet natural stage, maintaining lovely center fill.
I've read of complaints that busily produced studio albums can sound different. Well, who really knows their intent? I find them more interesting. Last I saw, there is a two-week free-trial of the BACCH Plug-in. With a computer and some Tech assistance, worth the time. Best, Pin
