I am looking to beef up my Optical Compressor investments. I am currently looking at a either a Avalon 747 or a Avalon AD2044. I already know there are some obvious differences i.e. The 747 has a Graphic EQ in the chain, the 747 has a side chain option, the 747 only allows for linked operation (the two channels cannot be operated seperately). Many of their specs seem similar.

Anyone here have this and use it for mastering?

I'm considering using it as a 2nd comp in the mastering chain after my Gyraf Gyratec X Vari Mu, or to compliment it. Sometimes using two compressor with subtle compression sounds better than just one, especially if they have different sounds (IMO).
