I'm gonna take issue with that. The DR sim in the Amplifire is one of the most realistic among several excellent sims in the box. The Alessandro I had for awhile was the actual physical amp that Marc Gallo had used as his reference in finalizing the model. The far field IR I shared ca. 2019 came from that cab and speaker (which Eminence makes OEM for Alessandro). I also have IRs from an original AB763 DR cab with its original Jensen 12. Although I much prefer the Jensen IR, the Amplifire DR sim with the Alessandro IR played through one of my monitors - or any suitably transparent speaker - is an incredibly good match for the physical amp/speaker. FYI, a critical piece of making a reference comparison is matching volumes. Whatever the volume you need for the amp to get a particular sound, you will need to play the modeler/monitor at the same volume. Once you've gotten a suitable match, you can (obviously) play the modeler at a lower or higher volume. It won't sound identical, but the difference is due to your hearing, not to any tonal shift in the equipment.
