Nice. I like the idea of using the LA-2A too, it's definitely one of my favourite compressors.

... which one works best for warming up tracks any suggestions?

 
what does 'warming up tracks' mean to you?
 

While I knew of the term "New York" compression, I wasn't aware of its specific implementation. Also wasn't aware of the other variations. Knowing the origins of common place processes fills an important gap for me. Thanks Scott (kamikaze) for the ref.

How about doing parallel compression within the compressor plugin itself? Check out the following video on the Klanghelm MJUC. After the initial "please subscribe/please comment" intro comes an EXCELLENT review of the MJUC compressor plugin. Somewhere around the 20 minute mark, the reviewer goes split-screen and brings in a second guy. Complete waste of bandwidth. But the first 20 minutes are well worth the time. I'm going to start a separate thread with this video, but it really fits here. The reviewer first mentions parallel compression just before the 4 minute mark. It then gets used later in the review.
