DENON is the first audio company in the world,so DENON is a DENON. Nothing more nothing less. I have also and the DENON PMA-720AE.

No headphones but if you are a professional you may have a stereo mixer so it is not a very big problem.

Denon DN -A 300m is bargain and value for the money integrated ampliwire..IT,s professional but it also good for music lovers and hifi at home. It,s not a high end ampliwire but a good budget/midprise ampliwire. The sound it,s like the Denon pma 720 AE, but you have more power.good allround sound, and good bass. A lot a inputs, but no headpnone input,,but that,s not a big problem. IT,s very well build and heavy, and very easy to use. Highly recommended for music lovers Who not have a lot of money to spend on high end equipment
