Okay, then the DSP must process the signals differently with different software versions.

Not exactly. I'm guessing what happened is this:

1.03 and 2.0 must somehow store the EQ presets on the hard disk slightly differently. When you upgraded to 2.0, it read the data straight off the disk and sent it straight to the DSP. Well, since the data was formatted differently, it meant the values sent to the DSP were not the expected values, causing the strange output levels.

When you went into the Equalizer screen and fiddled with the EQ presets, it rewrote the stored information in the corrected (new 2.0) format, and everything started working right again.

The difference between what I just said, and what you said, is subtle, technical, and semantic. So apologies if I'm being pedantic, I just wanted to make sure that we were clear on exactly what was happening. I don't think the problem is with the DSP or with output levels or with signals. The problem is with the way the EQ presets are stored on the hard disk.
