BEST COMPRESSOR EVER
I have several pieces of API and the tone has never let me down. Previously I was using a Chameleon Labs bus compressor. I was never delighted with it's sound but it did do a good job of keeping the bass energy in a mix happening.
We recently upgraded our mixing console and mastering loop on the Neve mixer I use, I wanted something to put some final polish on the mixes so the API came to live here. Zero regrets, this is a monster good sounding compressor.
Setting the controls on this takes a while to get accustomed too. It's easy to overdo it. After you find the right settings for the material you're working on it's transparent until you bypass it and realize how much it was doing to smooth things out.
The vintage feedback style is where I've ended up for topping off a mix and gluing things together. With the API 2500 things sound very smooth and polished plus the sound retains that full bottom end sound we've worked so hard to achieve.
My GF/music partner thought I was nuts to spend this much on a stereo compressor but when she came into the control room and heard four live recordings by a three-piece boogie band I mixed yesterday she got it and was grinning ear to ear about our new toy. All the tunes are grooving in a very positive way because all the parts are working together.
If you're looking for a powerful stereo compressor that can really pull a mix together you can spend more but you can't do better than the API 2500.
Good music to all!
