500+ Head-Fier
If you're going to EQ and your EQ just lowers the volume at certain frequencies, you shouldn't need to use Headroom management.The LCD-5 thread all got their pitchforks out when I pointed this out a month ago. Nevertheless, I'd like to at least try it out with them before making a decision on pulling the trigger. I'd rather not mess around with EQ either, but I'm curious what exactly is this holy grail I'd supposedly be missing by not going it. It would be straight up parametric EQ. I've done it without enabling Headroom management or sample rate conversion. It introduced some weird artifacts and i was told that might be the case. Not sure how I should configure them manually to account for the M-scaler. Or if there is a "right way " of doing it.
However, if your EQ settings would increase the volume at certain frequencies, you should enable Headroom management. For example, if the maximum EQ is say +5dB at 1kHz with whatever Q, then you need to set the Headroom management to -5dB. Otherwise, whenever you hit the 1kHz note and if it's super loud in the recording, that +5dB EQ would clip that note and create artifacts.
You shouldn't need to use sample rate conversion. Sample rate conversion definitely worsens timing accuracy significantly. You should never turn that on.
Now lowering the volume via Headroom management would also affect the soundstage depth.
The reason why people get their pitchforks out are because:
1) Some people just can't hear certain things. It may be equipment related. It may be hearing training related. Or it may be fundamentally hearing related. People don't like to be told they can't hear certain things. Especially if their hobby is audio.
2) Sometimes the improvements from EQ is so big that the sonic gain is better than the subtle loss of soundstage depth. So the problem is just ignored.
