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. I tried calling Avalon (they don't allow emails????) to speak with someone and it was hard to tell if the guy I spoke with really worked there (not much help). Has anyone used either of these compressors? Has Anyone had the opportunity to A/B them against one another, if so any notes on the sonic differences wud be appreciated? Any opinions on either of the units would be appreciated? Any other suggestions for an optical compressor to look at, other than a Manley ELOP, 1176 and LA2A, based on actual user experience would be appreciated? Thanks.
