Recommendation for new 5-ch Amp

There's also the Theta Intrepid. At around $1,500 new, it's a no-brainer

Almost bought some Emotiva stuff.. not bad stuff for the $$.. I actually heard some of it at the RMAF.. good for the money.. doesn't sound as good as Parasound or Sunfire though.. just my .02.. but if you are just starting out.. decent for the money!!

Maybe look at the Butler 5150 hybrid amp. I love my 2250.

Bryston 9Bsst2, Cary cinema series, or the new Moon multi-channel amps would all be upgrades from your Sunfire amp I would think

What is it that you don't like about your current amp? The amp is just one part of the entire system chain. If you can't identify what you like or don't like you'll have the upgrade itch forever. With any recommendations, you're just buying a brand name and not necessarily the right fit. For example, if you have Maggie's then you need both high current and stability into a 2ohm load. If you have more sensitive speakers then you don't need extreme power, etc. All electronics affect the sound. I don't feel as though you've given enough info to get the proper feedback and recommendations you are looking for.
