I have especially brought this amp because I absolutely do not like the look of old, used amps. Here me the Denon fully convinced -. Simple, elegant design, the whole body including the front are made of aluminum (only the buttons not). The sound is in my ears clear and unadulterated - the Denon are all signals so again as they come in, Ne them impose their own stamp - just as it should be! Farms were / are so first a couple Canton Karat 20, recently I switched to the Dynavoice DM6 - the latter are really cool boxes, the wide play over its price class! The Denon to fully exploit their potential creates - the Marantz amplifier of my father they sounded absolutely identical for me, this also speaks for the PMA-520AE. The number of inputs is sufficient for me, a second pair of oxen to connect is not necessary for me - who needs this feature, can engage in good conscience to PMA720AE.
In a nutshell: the Denon PMA520AE is money definitely worth - he gives the sound of unadulterated, is well made and has an elegant appearance. Therefore, a strong buy recommendation!
