I think that this specific Rotel is a sturdy amp. Having said that, i think that the Sunfire is both more versatile ( two different sounds in one amp ) and less fatiguing sounding. I would also recommend running the Sunfire in balanced / XLR mode if possible. Just make sure that your pre-pro is pinned out the same. Sunfire's use the "American" pin-out on XLR's whereas many other companies use the "European" pin out. Trying to combine a Euro based pre-pro pin-out with an American pinned amp will not provide the results that the components are capable of. If you need more info about the Sunfire, fire away. Sean
