Conclusion "Area DVD" Price Class Reference: The Denon AVR-X4000 is the prototype of an almost perfect AV receiver that leaves no aspect overlooked. The price is reasonable considering the performance, and the features are excellent. Notable mentions include the three HDMI outputs, high-quality video processing, integrated online music services, comprehensive calibration system, and HiRes compatibility with extended capabilities (gapless playback possible for key formats). The AVR-X4000 sounds exceptionally confident and impresses with an outstanding blend of acoustic harmony, dynamics, spatiality, and richness of detail. The coherent design is also evident in the fact that the X4000 sounds equally convincing in both stereo and multi-channel operation. The video section impresses with excellent upconversion of film material, although it shows slight weaknesses with video content. The initial setup of the very level-stable AVR-X4000 runs smoothly thanks to the clever setup assistant, even for less experienced users. The calibration system operates reliably and measures quite accurately, allowing us to ultimately attest to the Denon AVR-X4000 consistently delivering top-notch results.
