Or, you could buy
the Drawmer DL241 for about $700, and hear what the Composer Pro was _supposed_ to sound like- since it was basically a knockoff of the Drawmer design. I just sold my pair of Composer Pros, and replaced them with the Drawmers, in fact.
They do link for stereo, but then I have the RNC for that, and it's one *hell* of a fine, transparent 2-buss squeezer. My RNC sees a lot of use.
The Drawmers exhibit a vast improvement in noise floor over the Composers, and are very sweet indeed. The difference when using them in mono as a gate/compressor/limiter for bass or Stick is very much worthwhile: less noise, much less artifacting as the gate closes, what sounds like a much faster and much smoother limiter for overs (less crunch if I'm being inattentive about the levels). I'm glad I decided to make that change, and for me, it was worth every dime of the extra cash to make the change- I have one in my road rack for those one-time-only, no-retakes live recording dates...
Your mileage may vary, of course. Don't let me sway your opinion.
On the other hand, the Composers certainly do have a couple more knobs and at least twice as many LEDs on the front, and those wicked cool high-tech-looking brushed aluminum rack ears. And they are ungodly cheap. And that counts for a lot around these parts, seems like.
But I *like* my Drawmers. They are a better tool for my own projects, and I've had them both.
