While this device appears quite appealing, I'm somewhat uncertain about the absence of an HDMI eArc input. If it did include this feature, I would be inclined to make a swift purchase, as it would enable convenient control using my television remote.
Interestingly, there is an alternative product available that offers HDMI functionality and makes use of the identical chip found in the Sabaj a30a. This product is the Harman Kardon Citation Amp. Regrettably, it has been taken off the market due to numerous instances of overheating reported by users.
The trend of incorporating HDMI inputs into devices is becoming increasingly noticeable. This feature proves exceptionally convenient and aligns perfectly with the preferences of individuals who utilize stereo systems or a combination of stereo and subwoofers as their primary home audio setup. Brands such as SVS, Audiolab, and NAD are progressively integrating HDMI inputs into a wider range of their products. Therefore, the anticipation is growing for Chinese companies to follow suit and address the noticeable gap in this aspect.
