Decent Power Amplifier for Rotel RA 6000 Amplifier

I have a Rotel amp with the same power and it drives all the speakers I’ve owned and tested.  Agree with selecting your speakers 1st and then checking out power amps that will meet your needs.  You won’t really know until you listen with your speakers in your listening room. 

Yes to answer your question I have Arendal and Revel speakers paired with my Rotel setup.  The Arendal 1528 series is excellent.  It depends on how much speaker you need.  They have a huge standmount, a monitor and massive towers.  I recommend the Revel PerformaBe series too.  I have the M126Be standmounts and they also have several tower versions.
