I don't love the QC 2203 model, actually found the recent HX one to be much better.
I have found a REALLY good user-created 2203 capture, though. Also like the Jub 2555 factory captures.
As a side note: nothing is really comparing to my own captures of my Electra Dyne, regardless of model/capture/amp brand.
Setting my own preference/obsession with that amp aside
, I'm wondering if it's more because the capture includes the speaker impedance curve of the actual cab I'm using when playing the capture, if that makes sense? Not sure if it's placebo, but it does seem to give that extra realism/holy sh*it factor. It reminds me of the differences in detail/accuracy/feel when I got the SIC right in the FM9, for example. Whereas when I play other users or factory captures, or the factory models, the SIC piece of the puzzle seems missing and it feels/sounds a little flat.
(As background: I made the capture using the Slave Out on the Dyne head, with the head connected to my Recto 2x12 cab and still producing sound. And when I play the capture, I'm using the same 2x12 cab with my Matrix as a power amp.)
