Good day
If I connect my Harman Kardon speakers + subwoofer, will this produce good sound?
Unfortunately Harman Kardon does not offer me a 4K solution.
I use this receiver with Harman/Kardon HKTS 30 (5 speakers and 1 subwoofer) and can't complain, plus the 80W output is more than enough. However, I don't know what you mean by 4K because that refers to picture resolution and not sound. In any case, 4K is supported.
