Sounds like you want to experiment with recording via an audio interface that has a good converter. I used to have a Zed12FX which I thought was awesome but I didn't like the built-in usb 1.0 which only records 16 bits and records in stereo only. I tried to connect the main XLR outs to another audio interface. The result was ok but not as good as recording thru the audio interface alone. After trying so many different audio interfaces (M-Audio Profire 2626, Focusrite Forte, Presonus 1818 VSL, Steinberg MR816CSX), I landed on the Universal Audio Apollo which I think has the best converter and the lowest latency. It's hard to let go of your hardware especially a nice once like your Dynacord. I still have my Zed and it's stuffed in the closet. LOL.
