I'm looking at preamps with cab sim (like Mooer Preamp Live) and multieffect units (NUX Cerberus, Mooer Black Truck). Some products have an XLR out but most don't. I want to plug the thing directly into my Focusrite Scarlet interface. Would connected via XLR cable sound better than via normal instrument cable? I wonder if XLR out is a feature that improves sound or something that does not matter to me. If I decide for a product without XLR out, do you think a DI-box would be good? If yes, how much should I invest or what should I look out for when buying a DI-box?
