Intuitive interface layout, practical display
The front panel layout is clear, with the power switch, Config button, and indicator lights easy to identify—you can figure out how to operate it without reading the manual. The VFD display is very practical, clearly showing source type and zone status. The font is clear, the color matching is comfortable, and you can see it even from a distance. By the way, the color changes of the LED indicators are intuitive; you can tell at a glance if the device is on, connected to the network, or in standby. It’s very user-friendly.

Zone-specific EQ, sound tailored to taste
I love the EQ feature in the HoloHome App—each zone can be adjusted separately. When watching movies in the living room, I crank up the bass for more immersion. For classical music in the study, I boost the treble to hear every detail. There are presets like "Rock" and "Jazz" too; when I’m lazy, just pick one and it sounds great. It feels like each room’s sound can be tailored exactly to my taste.

Feedback is valued, new product iteration speed is amazing
I’ve communicated with OpenAudio via email a few times, and once specifically asked about Google Cast support. They said it was in development and would be available soon. I thought I’d have to wait a long time, but they rolled out the update supporting this feature much faster than I expected. This attitude of valuing user needs and responding quickly is far better than many brands. I really think their production team is incredibly strong. I’ll keep following them and hope their future products continue to surprise us.

Excited for 8 x Google Cast to Manage Our Busy Home Audio
Honestly, I’ve been eagerly waiting for the Google Cast version of this amp, and now that it’s available for pre-order, I jumped on it right away. As a busy mom, I need a reliable multi-zone streaming system so I can play different music or podcasts in the kids’ playroom and kitchen. I especially love the 8 x Google Cast feature because it makes managing audio in multiple rooms super easy and flexible. I’m excited to finally have a versatile setup that fits our busy household life. The anticipation is real and I’m counting down the days until it ships so I can start enjoying some background music while handling the daily chaos.
