Hi @jijoh123 yes they are a bit different. I owned a Rogue Atlas 3 paired with a Rogue RP1 pre amp. Pretty powerful combo, muscular for sure, I could have easily stuck with the set up. There was an audible hiss and hum though, I couldn’t ignore it. When I swapped in an NAD pre amp, quiet. Their tech support was great, gave me several ideas, ultimately the noise floor of the preamp was a bit to high and the noise was present with their preamp.
I sold and bought the Cary. Little less power but my Volti Razz speakers are pretty sensitive, 96 to 99 db depending on who you listen to. So the decrease in power didn’t mean much. For me the ability to switch back and forth between UL and Triode mode is cool, depending on my mood. Also the rectifier section on the newer SLI80 makes it less of a syrupy overall sound, what I remember about Cary back in the day.
Honestly I don’t think you could go wrong choosing either.
