If you have Marantz 6005 or 6004 series products this is the Network Player to match. It also does internet radio, Airplay, Bluetooth and Spotify so it ticks almost all the computer/internet music boxes.
So it is any good? In a word yes. It's feels reassuringly weighty and well put together like the PM6005 and CD6005 and comes with a decent remote. The sound compliments the other Marantz units perfectly and the Ipad app to control it is nicely designed and easy to use. It's handy to be able to operate the unit from the front panel as well.
Basically it's a really nice Network Audio Player for £499.
