I found that the samples I had of this DAC were all running a couple of tenths of a dB hotter than the pretty standard internal DACs. Since the ear detects small loudness shifts as everything and anything other than simple volume differences, it wasn't surprising that it sounded different.
@JEFF, YES, I have often thought a useful option on digital graphical equalisers would be a "normalise" check box that would automatically normalise the individual band attenuations so the over SPL gain was kept to 0. i.e. if you raise one band all the others would marginally decrease.
This would have two benefits:
- Reduce the subjective effect of louder being better
- Potential marginal improvement by avoiding clipping and digital rounding errors in the scaling.
Ought to be a fairly simple thing to code and *I think* (with good user interface) provide a more intuitively understandable tool.
