I love the FATSO Sr UAD plug. I usually only use it on bass and drums though, not on the 2bus.
IME the UAD plugins nicely capture the ”essence” of their hardware counterparts, and in some cases sound spot on, but usually fall a lil short on the extremes of the operational ranges. Platinum records are being made every day with UAD plugs, so I’d say they’re good enough to get work done
But! for weirdos like me, having and using a certain UAD plug for long enough time always gives me GAS for the hardware eventually. But every time, its a ”want, not need” type of thing. For example, now that I have a hardware SSL G bus comp clone, I’ve been procrastinating A/Bing it against the UAD plug in the fear that I will be unable to hear a big enough difference in sound between the two
Only area where I can hear a distinct difference against the plugins are in mic preamps. Even with all the UAD unison voodoo etc, my lowly DBX 386 tube mic pre with NOS mullards smokes the UAD 610A & 610B, every single time.
