I Used this amp to expand my RZ50 from 7.2.2 to 7.2.4 so now I can run 4 Atmos speakers and it sounds so much better. I was missing the back atmos now I have full 360 degree sound. This amp sounds great . I have it powering my klipsch RP-600M as my surround rear speakers plug into the RCA pre output. Then you take and wire your rear height/ atmos speakers into the surround rear speakers positive and negative post . Then when you set your speaker configurations to 7.2.4 it gives you a second height channel but takes away your rear surround and that’s why you use this 2 channel amp for your rear surrounds .
I would recommend this to a friend!

The PERFECT amp for my computer room audio!

I'm not using this as part of a surround-home-theater set-up, but rather to drive a pair of Infinity Primus 150 bookshelf speakers, and send a signal to a Polk PSW10 powered subwoofer, all connected to my iMac 5K. I bought the amp (and sub) in January, 2019 and it has been fantastic! (I've had the Infinity pair since 2005.) I replaced a 50w/ch Audio-Source amp that suddenly decided to stop working, and was very happy to find this pure, connection-ready 75w/ch amp from Onkyo! Better, fuller sound; the Infinitys NEED a great amp, because THEY are awesome for acoustic music and subtleties of performance-space ambience.
I listen to mostly acoustic music (classical and jazz)
