After the July firmware update, I brought down the treble/mids peaks a bit. CA altered the signature quite a bit between January and July for the better.
I have the ePro large now so I expect to change the equalizer over the next few days. Not sure yet.
I'm not too happy about the volume issue, but I must live with it. I'm waiting until next summer to upgrade -- hopefully to something from the next generation. This is good enough until then, especially for $150. Upgrade that would be somewhat significant would be the Gemini, but that is more than double the price for the same generation. I would rather wait for something more compelling from the next generation.
