Lab Measurements and Bench Results: What the Numbers Say

Measured data helps separate impression from repeatable performance. Below are focused bench findings that match listening notes and reveal where the unit shines and where test conditions affect results.

DAC performance, jitter, and wideband response

DAC SINAD and dynamic range are competent for this class. SINAD sits slightly below the prior generation but remains solid, while dynamic range and linearity stay accurate down to very low levels.

Jitter tests on HDMI and Toslink show stable clocking and a well‑designed input stage. That stability preserves timing and keeps audible artifacts low across sources.

Frequency response reveals filter‑related behavior: wideband SINAD at 48kHz test tones is impacted by out‑of‑band energy. Higher‑rate (192kHz) tests reduce that effect and show improved measured response.

Amplifier power, multitone, and sweep behavior

Measured power into 8Ω and 4Ω shows respectable output with useful headroom. The shared PSU design helps sustain transients when several channels demand current.

Multitone and sweep tests are strong for an integrated receiver. Results are not desktop‑DAC class, but they confirm reliable performance under realistic multi‑channel loads.

Variability, pre-outs, and practical takeaways

Some measurement variability arose from grounding and the unit’s double‑insulated design. These differences reflect test setup sensitivity more than everyday listening impact.

Practical outputs: 2V unclipped pre‑out level was verified, making integration with external amps straightforward. Per‑pair amp disable functions as advertised, easing upgrades.

Metric	Result	Practical Meaning
SINAD	Slightly below previous gen; class‑solid	Clean DAC performance for music and movies
Dynamic range & linearity	Good, accurate to low levels	Detail retrieval and low‑level fidelity
Jitter (HDMI/Toslink)	Well controlled	Stable timing and low artifacts
