He changed it because there were bugs that allowed you to plug in extreme values that caused the DSP to glitch at certain volume levels. I don't know exactly what the new limits are.
I'm pretty sure it was in response to bug number 1852:
Start with a flat EQ, any volume setting (mine was at -13db), any music file, 'home/DC' mode with L+R locked on the EQ.
Take the first band and set its frequency to 18hz (not khz) and set its Q to 20.0.
Decrease the gain on this band (with a fixed Q) and you will hear:
-6db= SEVERE Distortion in the RIGHT CHANNEL ONLY, while the left channel is fine.
-7db= Right channel gone, left channel fine.
-27db= Both channels fine again.
I hope this is somehow related to the odd distortion I'm hearing in the right channel on some pieces of music with my heavily-tweaked EQ.
Otherwise, the granularity of the adjustment is much improved over b13.
I think that the granularity hasn't changed, I think what happened is that they fixed it so that there are no longer any "hidden digits" as you're adjusting things. This was bug fix number 1840:
When changing one of the detailed parameters in the equalizer, for instance, if changing the Q or the frequency, sometimes you will press the vol+/- buttons on the remote and the digits on the screen will not appear to change.
This makes it seem like the remote is locked up and you get irritated.
In actuality, the value is changing, it's just changing a decimal place that's not displayed. If you press the vol+ button ten times slowly, it will eventually change one of the digits you can see.
This only happens when certain numbers of decimal places are shown. Not all the time.
I ran into this bug several times when trying to adjust the Q and the frequency for my RTA passes on my car system. Sometimes I have to change the Q to pretty large values, or to change the frequency of a given band by a significant amount.
