Whether one of the amplifiers sound like just anyone can answer for themselves. About taste in music can not argue and whether a hearing with this amp like depends on many factors (speakers, room acoustics ...). Opinions about there to be sufficient in the Internet. The aural comparison with a PM94 Marantz needs of small Denon nothing to fear, he plays very neat. I like the PMA720AE very good. The power of 2 x 85W is sufficient to get on all boxes I tested with all neighbors trouble. The speaker switching and EQ can not switch to the system remote control.
I bought the machine through Amazon Warehouse Deals. It was "used as new" with advertised and so I got the device in an apparently ever opened carton with carton. The shipment was carried Amazon typically very fast and tidy. The amp is like new without Markel! Thanks for that. Only the batteries of FB were missing.
Conclusion: Great amp. I got it new for 190. Price / performance ratio is great!
