Dan, Thanks for quick reply.
To answer your points:
1. Older version was uninstalled before installing 2.0
2. DPS reflector was selected as output
3. Volume Boost was checked
4. Macbook Air is the profile I use.
Maybe just a bug, but almost no difference on my MBA with 2.0 but significant difference with 1.0.7
Of note installed new version on my iMac, with good results. It’s just my Macbook Air
