Customer Reviews
Solid K5 Pro Gaming DAC
I bought the K5 Pro Gaming DAC to improve my PC audio, and it's been a game changer. Ordering was smooth on their website. It arrived well-packaged in about 6 days. Hooking it up was simple, just plug and play. The sound through my headphones is much clearer, and I can pick out details in games I missed before. I did have a small question about the drivers, and customer service responded to my email within a day with helpful instructions. The build quality feels sturdy too, not cheap plastic. For the price, it's a really strong performer, and the support was responsive.
Great value on BT20A Pro
Got the BT20A Pro during a holiday sale. I was looking for something affordable to power my older speakers, and this fit the bill perfectly. The discount made it even better value. It arrived pretty quickly, and the sound quality for the price is honestly impressive. Definitely feel like I got a good deal.
Love my new P3 Preamp!
Oh my goodness, I just received my P3 Tube Preamp and I absolutely love it! The sound is so warm and rich, it's exactly what I was hoping for to pair with my turntable. It was super easy to set up, and it looks fantastic on my shelf. I'm so glad I decided to get this. What a great piece of kit!
Good sound, slow shipping
I ordered the Fosi Audio V3 a few weeks ago after reading some good reviews. The sound quality is definitely there for the price, really clean and powerful enough for my bookshelf speakers. Setup was straightforward, no issues at all. My only gripe is that it took almost two weeks to arrive in California. I get that shipping can be slow sometimes, but I've had faster delivery from international sellers. Still, happy with the amp itself.
Reliable as always
This was my third purchase from Fosi Audio, this time for the ZA3 Balanced Amplifier. I've had their BT20A Pro and a Box X2 previously, and they've always been reliable. The ZA3 continues that trend. It arrived in about a week, which is consistent with my past orders. The build quality is as expected, solid. Performance is great, running my speakers without a hitch. It's nice to know what you're getting when you order from them, no surprises.

Hey, thinking about grabbing the V3. How long does shipping usually take to New York? Need it kinda soon.
Can you use more than one discount code at a time? Got a newsletter one but saw another for new customers.
