Decided to run by a few experiments with the W900: precise equalisation with the use of FR curves. After a few weeks of trial and error (further delayed by my laziness) I think the results are ab-solutely incredible.
Using measurements from my DIY setup (link in my sig) I was able to isolate the peaks, dips and spikes, and sort of "clean up" the W900 with the specific targeting of particular frequencies and modifying Q-values for refinement.
Here's what the "special sauce" does subjectively:
- Increases treble sparkle but maintaining the W900's signature treble control
- Boosts airiness
- Removes the slight nasally quality of the vocals that is apparent next to reference monitors
- Improves bass-midrange separation
- Reduces note weight
HOWEVER, due to the methodology used to create this EQ profile, what I experienced may differ from person to person due to a number of variances (unit variance, custom vs universal, insert depth etc.). At any case, I'm confident that anyone would find an improvement; just A/B with & without and tell me what you think.
