Snagged it, can't wait for delivery!
I finally snagged the Ultra-GC and can't wait for it to ship! The reason I chose it is super simple—other amplifiers only support Google Cast for 1 zone at most, but yours supports 8 zones. Plus, it has 8-zone support for both AirPlay 2 and Spotify Connect. This functionality totally outperforms similar products. Just imagine, 8 zones can play different streaming music separately without interfering with each other. Everyone in the house can listen to their favorite content in their own space. That experience sounds amazing. It already feels worth it just looking at the specs. I can't wait to try out these powerful multi-zone features once it arrives!

Bluetooth signal is strong
I often connect my phone to HOLO-WHAS Max via Bluetooth to play music in the living room. Sometimes I walk to the balcony, which is about ten meters away with a wall in between, and the music still plays smoothly without any lag. When cooking, my phone stays in the living room, but switching songs or adjusting the volume in the kitchen is easy, and the signal isn’t affected at all. Last time friends came over, my phone was in the bedroom while the amplifier was in the living room—the Bluetooth connection stayed stable, playing music all night without interruption, and the sound quality remained excellent.

Quick response, new product updates exceed expectations
I emailed OpenAudio before, asking if HOLO-WHAS Max supports Google Cast. They replied quickly saying the feature would be available soon. To be honest, I didn’t expect much, but I was really surprised by how fast they moved. It wasn’t long before news of a new version with this feature came out. This responsiveness to consumer needs is really impressive. I’m curious how their team manages to be so efficient. I’ll definitely keep an eye on their new products and look forward to more surprises.

Pre-Ordered Ultra-GC Excited for 8 Zone Google Cast
Alright, a friend recommended me to check this out. I actually spent quite a while deciding between the Ultra-GC and Plus-GC. For now, I went ahead and pre-ordered the Ultra-GC to give it a try. What really sold me was the 8 x Google Cast support. You just don’t see that kind of multi-zone casting with other brands. It’s on a whole different level.Really hoping it ships soon because I’m super eager to experience this all-in-one device firsthand!

Can’t Wait to Try the New 8 x Google Cast !
Big thanks to OpenAudio for dropping new stuff so fast, haha. I already placed my pre-order and I’m really hoping it ships soon. Gotta say, just like a bunch of others here, I got hooked by the whole 8 x Google Cast thing. Super excited to try it out once it shows up!
