The result is one of the fastest, most dynamic and most engaging multi-channel sounds I have heard in my 7.1.4 Dali Phantom/B&W DB1D system. Dialogue is incredibly crisp and intelligible through the AT screen that can often confound EQ systems, and the resolution of individual detail across the object-based audio formats is frankly breathtaking. Ramp up the volume and that enormous power supply ever sounds overwhelmed, with the SPL swelling with sumptuous smoothness.

A wonderfully nuanced performer, Denon's mighty new AVC-A1H offers clarity and detail not found in lesser receivers. Its excellent channel steering and massive soundstage envelop the viewer in sound. This supremely powerful AV receiver is also capable of lightning-fast, explosive dynamics. However, to unlock the best it has to offer, I'd strongly recommend you look at Dirac Live Bass Control, or Audyssey Pro if you fancy yourself a deft hand at such things.

The A1H's impeccable build quality, extensive connectivity options, and cutting-edge features, such as Audyssey MultEQ XT32 and Dirac Live upgradability, make it a formidable contender in the high-end AVR market. While it may not be a katana in the literal sense, it cuts through the competition with its exceptional performance, delivering a truly immersive and captivating audio experience.

An imperious flagship AV amplifier that more than justifies its high price with an incredible feature set and stunning sound. Denon's A1 class has done it again.

The AVC-A1H stands as Denon’s best multi-channel amplifier to date. By a significant margin. Not only does it boast a staggering number of speaker channels, but it also sounds even better than its predecessors.
