DBX Compressor mods

I'm still waiting for the Flux Bender to return from Recording Magazine's review.  A few important Mixes are on hold till its return, but I'm keeping busy meanwhile.  Yesterday (my Birthday) was technically a day off, but I modified my DBX 160X compressor.  I did some technical research and purchased some Burr Brown opamps to replace the stock opamps.  The goal was to improve the sound quality of the compressor, which I previously modified by adding an output transformer (recapped it as well).  This was my first experience working with integrated circuits.  Thankfully, it went smoothly and I wound up with a better sounding compressor.  The DBX compressor sounded good to begin with, but I could hear something about it I didn't like.  It had a cheap sound to it, which could be described as reduced sub bass, reduced highs and a presence bump in the upper lows (Focused around 110hz, but widely dispersed).  I really hated the sound of its bass presence, so that is the main factor in deciding to modify the compressor.  After replacing the stock amplifier chips with much higher quality (and modern) Burr Brown amplifiers I noticed a big sonic change for the better. That low presence is gone, but the compressor seems to also have a wider frequency response and a more accurate sound.  I'm very happy with its sound now.  In fact, I'm so happy with the sound I'm thinking about buying a few more of these compressors and modifying all of them!
