Hey there. I’ve had the new RA180 for a couple months now and right off the bat it has amazing detail and clarity and bass. Bass was immediately more substantial when compared to the NAD M33 that I have on hand. This was in bridge mode, so it’s twice the power of the NAD. Really detailed with wide soundstage. It easily runs the KEF Blade and Reference 5 Meta speakers. I never tried bi-amping, just running bridge mode which is 400 watts per channel. Build quality is great but the buttons and controls are not made of metal. My mind made them metal when looking at the photos, but they aren’t. They still feel and operate with a solid feel. Add the RS150B and ANY speakers and you’ll have an incredible system.
