Interesting timing on your post.
I'm tracking a set from last weekend. It was taped from exactly the same position in exactly the same bar with the same band as a recording I made a couple months ago. Last week I was running KM140s DIN directly into the 722. It sounds pretty good. In fact I have used outboard preamps religiously with the 722 but I needed to run light that night. I'm happy with the result.
In the set, the artist mentioned the name of a new song that I didn't know when I tracked the previous set. So I listened to the other version. That night I was running KM140 XY through the portico. Now I'm not as happy with the set fom last weekend. It sounds good, yes it's better than adequate, but I can easily justify carrying the additional weight.
