Hi everyone.....i recently came across an Avalon VT 737 sp preamp that i could pick up for a fair price. I have heard nothing but incredible things about this piece of gear and im sure it would be quite a step up from what im using now.... my main concern is that at the moment im only using a MBOX as my interface. i plan on upgrading to something better in the next few months. but for now, would this preamp even shine the way it should going through such a entry level interface?? thoughts?
