Highly transparent presentation reveals fine detail and keeps dialogue clear in dense soundtrack moments.
Feature set is extremely deep, with 20-channel processing, HDMI 2.1, and advanced bass management.
Cons

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 95/100
Reviewers describe a very cinematic presentation with exceptional transparency and fine detail. Bass is called superb, with a silky smooth bottom end, strong tonality, tightness, and impact, while dialogue stays clear even in chaotic scenes.
Transparency Resolution
96/100
The review explicitly praises wonderful transparency and fine detail, saying it can extract the subtlest nuances from soundtracks. Dialogue remains clear even during chaotic moments, which supports a highly revealing, low-veil presentation.
Tonal Balance Musicality
94/100
The bass is described as superb, with a silky smooth bottom end, strong tonality, tightness, and impact. The overall sound is presented as cinematic and engaging rather than clinical, with no meaningful complaints about brightness or harshness.
Dynamics
97/100
Dynamics are singled out as clean, powerful, and thrilling, with the amplifier going from deathly quiet to heart-racing impact. The review also stresses massive volume levels and outstanding power reserves, making this a clear standout for drive and headroom.
Soundstage Imaging
93/100
The Fusion creates a massive sound field that is big, bold, and powerful, with immersive scale befitting film soundtracks. The review emphasizes clarity and separation in dense scenes, though it says less about pinpoint imaging or depth layering specifically.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
89/100
The review comments on extremely solid gold-plated five-way speaker posts, and the product’s execution appears aimed at serious theater-duty use. Beyond that, the reviews say little about long-term chassis construction or internal layout, so the evidence is limited to the visible hardware and practical sturdiness mentioned.
Features Connectivity
95/100
This is exceptionally well equipped, with 20-channel decoding, HDMI 2.1 on seven inputs and two outputs with ARC/eARC, 8K/4K120 support, and extensive bass management. Dirac Live with Bass Control and Active Room Treatment, plus network control, automation drivers, and multiple analog/digital connections, make it one of the most feature-rich units in its class.
Value for Money
74/100
The review is blunt that it is very expensive, calling it a stretch at two to three times the cost of competing flagship receivers. Even with its impressive performance and feature set, the reviewer’s value judgment is clearly negative relative to similarly positioned alternatives.
