At Dali censor 5, he has already withstood every comparison. Even more expensive amplifiers from leading manufacturers he has already made in their place. To 600 euros, my advice would be to listen to time. The value for money is unbeatable (for me). Especially since I got it for 220 Euro. As a player I'm using the Marantz NA7004 via Bluetooth from the notebook (Flac and MP3). Tested all the Direct mode.
