Transcoding from simple stereo MP3, should destination use simple too?, [was “dbpoweramp settings, need help!”/TOS #6] Options

[daniel.ok]

I have a small problem here: I want to re-encode my MP3's from 320CBR to -V2 with dbpoweramp (lame 3.99.5) but here is the trick: I have MP3's at 320CBR Stereo and MP3's ar 320CBR Joint Stereo. All I want is that Stereo\Joint Stereo remains the same, only quality modify to -V2. So, when I choose from dbpoweramp\advanced\channels I choose [auto] but this modify my MP3 always to Joint Stereo. Also I choose Stereo (auto) (CD) but it's the same, final MP3 is Joint Stereo from Stereo source.
What should I pick from channels option? (Force Stereo I suppose it's not the way to go, or is?) I've tested another ripper/converter and it was more simple: when I choose Joint Stereo - MP3 is JS, when I choose Stereo - MP3 is Stereo.

Also I have one more important question: It is right what I do? (keep the same type after re-encoding, Stereo - Stereo, Joint Stereo - Joint Stereo) (*please note that I convert MP3 to MP3)

Thank you, Daniel

It's only a problem if you can distinguish a difference between the two as you would typically use them.

Unless you're doing some kind of channel-based post-processing you are probably better off using joint-stereo regardless of the source so long as it has content in the center.

Before you ask any other questions about quality, make sure you read this if you haven't already:
