Is the Denon Ah-D7200 worth the upgrade from the STAX SR-009D?
Verdict
Downgrade
The Denon Ah-D7200 actually scores 10.0 points below the STAX SR-009D, so on aggregate review consensus this is a step backwards. The gains are concentrated in value (5.5 to 7.0). You do give up ground on sound (9.5 to 8.0). On paper: weight 594 g to 385 g. Worth checking: drivers per side goes 2 to 1. It is at least $1641 cheaper, so the lower score comes with a saving. Only worth it if a specific feature above matters more to you than overall quality does.
What actually changes
Sub-scores both products have, on the same 0-10 scale. Bars extend right for a gain, left for a loss.
