Thus, I was also once delivered only one box, very solid and securely packaged. But after recently testing was clear to me that I will not return them, but the couple Complete! What convinced me is her clear, balanced sound, absolutely unobtrusive comes even at high volume levels and thereby also reveals the finest details. That was me really from scratch that you can still hear such things as breathing of the singer at higher volumes. Although my previous systems sounded not bad (for me), had "sound" but produced only a mush of sound with pounding bass in comparison. Thus me the NS has 777 truly "open ears".
I was a little surprised that the speakers, despite their considerable volume in the bass does not produce the pressure that I know of much smaller cheap parts. Maybe Yamaha has postponed for a balanced sound characteristics, but what then would my full consent. Maybe but that is also due to my Denon PMA520AE which indeed according to many reviewers has a very neutral sound.
The PMA520AE I can recommend as an amplifier to the NS 777. He is going from the boxing quite strongly demanded (max. 2x70 watts RMS, the NS 777 are designed 100W), the combination may sound but excellent. That was me also new features: volume control to stop when input 0 and no noise or hum!
A little tip for ordering: invites ever on your cordless screwdriver. To fix the feet with a screwdriver is quite a torture because very stiff screws enclosed with very long thread.
