RF's goal is to make amps that put out lots of power. Their amps are almost always underated, the 100ix is no exception. SS's goal is make an amp that's very musical. They are better at different things and his is an example of the tradeoffs designers have to make. Since you are using this amp to power a pair of subs, I would suggest the RF. With subs, more power is a better choice than accuracy. Not that the RF isn't accurate, just less so than the SS and I don't mean to say SS's are not powerful, just less so thatn the RF. If you were using this amp to run midbass, midranges and tweets, I'd recommend the SS. When you look at the spec's for these amps you will notice that the RF amp is only rated to 2ohms while bridged. This is another example of the underating sceme RF uses and in this case that spec is more of a suggestion. Many, many people on this group have run their RF's long and hard at a 1ohm bridged load without any problems. Most of the stress of this is placed on the amps power supply, but these are tough amps that can take the punishment. SS's are rated to take this load in their "high current" mode, but you will lose power because SS's aren't really what we consider high current amps and aren't optimized to run at low impedences. Overall you will benifit most from the RF and considering the above, it's almost a perfect amp for your setup. I don't know if you've hooked up those Orions yet, but I think you will be pleased. I have a pair of the DVC XTR 10's and I love them. Even though their only getting 100W! Hope this helps, Victor Albert
