Those McIntosh speakers are some of the best I’ve heard in a near field setup . They just bring music alive !! Like us mcintosh owners know because of our power meters , even the 50 Watts rms this little guy provides is a ton when it’s real McIntosh power! Overall this is one of my favorite systems.
The MXA80 is almost identical to the MXA70 just a newer version of usb decoding for the Dac.
There is one Mxa70 for sale on this website for really cheap
