NAM Seems to add a DC offset when any capture is loaded with no IR. Using any post EQ high pass, even at the lowest value and steepest slope clearly removes the offset, as expected. I'm not an expert on this, so I'm not sure to what extent this affects subsequent plugins or possibly an interface out to power amp/cab, and it's not hard to fix after the fact, but it does seem like it shouldn't be there.

To Reproduce
Steps to reproduce the behavior:
1 Open a DAW or gig performer
2 Add a NAM instance and an RTA of some sort after it
3 load a few models, and increase the out level if you don't see it - but you should see a hump in the sub range of the chart that is constant.
4 Add a high pass at the lowest possible setting or add an IR to NAM, and you should see that hump disappear completely even though your filter doesn't include it.

• Windows and MacOS
• Plugin version 0.7.3
