On the DL-241 compressors, we offer a wonderful modification service that includes a full audio path upgrade, power supply modifications, dual sidechain modifications, input and output audio coupling and dual VCA path upgrade as well.
Here is what the service includes:
1) Burr Brown input and output stage modifications (gives the unit a more full detailed three dimensional sound with increased frequency response).
2) PSU re-cap and modification: lowers noise, re-rejuvenates and helps increase the current supply. It also gives the unit a fuller sound.
3) Dual "A" Rated VCA installation for the lowest possible noise from the design.
4) Cleaning of all electro-mechanical switches and potentiometers.
5) Dual Sidechain Modifications for smoother compression and less compression on Low Frequency material.
The result is a Professional compressor that Pro Studios will want to use daily for any number of tasks.
These come out sounding extremely musical with excellent headroom and dynamic range in thier price range.
