ROTEL RAP-1580 MKII Amplified Surround Processor 

Both are really solid, and I don't think you'd go wrong with either.

Hello Alexandre, thanks for asking. These are really different products, at different price points. The Rotel is powered at 100 watts x 7 channels, whereas the McIntosh is a processor needing a power amp. But the MX 123 offers some nice upgrades as a processor, including eArc for your TV sound, video upscaling to 8k, 13.2 channels vs 11.2 capable, network connectivity etc. Please reach out to us if you'd like to discuss further: ask@gramophone.com

I haven't heard anything yet but they are about due for it imo. Or at least a minor refresh with HDMI 2.1 and some processing updates.

If I were a betting man, I'd say they are about to come out with something combatable with 8K, eArc, and maybe a touchscreen. Speculation only though.

After my Yamaha natural sound receiver died after 3 years I bought a Rotel in the late 80’s, it is still going strong and used every day !
