Of course it doesn't change the hardware, but I really don't want to adjust EQ settings to try and match what they've done when a quick reload of the FW can be done (and there is only one custom EQ setting). They definitely have been tinkering with the sound along the way. Not saying one is better or worse, just sharing my observations.
Well I did try EQing. That didn't work at all. It seems as though with firmware 2.0 they took off more than 10db from the 30-100hz regions because I could not eq that to save my life. And then with fw 1.23 eqing the same region was too much so I think that they definitely took off more db than you can eq for.
