Before having owned these two, I had been using the UAD Manley Massive Passive as my main go-to EQ. I used it for most all purposes, and I thought I was well off. In the past, I had demoed these a few times, but barely listen to them.
Then I got an API 512c preamp, and I loved its sound. So, I gave these another try in shootouts against the Massive Passive. They both made me find the Massive Passive to oftentimes be downright muddy in the low end.
The overall character of these — especially the 560 — is exactly as advertised: punchy and tight. Their top end has a specific sheen that takes a lot to get harsh. Heck, they'd be great for mastering, even.
I run a small home studio, and this was the best upgrade I've gotten in a long time.
