Heavy duty hardware. Native casting is a dream
Finally, a rack amp that doesn't force me into the Apple ecosystem. 1600W total power is no joke—the headroom on this thing is insane. Sound is super clean (no hiss even at high volume). The HoloHome app is great for the initial zone routing and EQ, but once that’s set, I just use native casting from my apps. It’s expensive, but when you consider it replaces 8 separate streamers and a massive power amp, it’s actually a bargain. 10/10 would buy again.

Perfect for our showroom. Serious power and flexibility
We installed the Plus-GC in our 5,000 sq ft showroom and the performance is rock solid. We needed something that could handle 16 speakers and provide different 'vibes' for different sections of the floor. The Google Cast integration makes it so easy for any of our staff to just grab a tablet and change the music in their specific zone. It’s been running 10 hours a day for a month now and stays surprisingly cool.

The only real choice for a Google Home household
I’ve tried other multi-room amps that claimed to work with Google, but they usually only support one 'cast' stream at a time. The Plus-GC is a beast because it actually gives me 8 independent Google Cast instances. My kids can cast Music in their rooms. Plus, with 100W per channel, it’s driving my big 8-ohm floorstanders in the living room without breaking a sweat.

Super Excited for the HOLOWHAS Plus Google Cast Edition
Finally pre-ordered the HOLOWHAS Plus Google Cast version! Been waiting so long for this. I can’t wait to set it up and stream music throughout my house. What’s even crazier is that it supports 8 x Google Cast. I just want it in my hands right now!

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.
