Hello, Thank you for the quick reply.
Afrogt, When playing with the Denon i get the feeling it working like hell to drive the speakers. Like the Denon gets exausted, no dynamic, no punch and loss in details. The Nad t777 and t787 have the Holmgren powersuply But i dont know if it will match good with the D500. The Nad i had before (t785) had a more basser or darker tone overall.
oztech: I will take a reading on those, But I rather go for an A/V receiver.
