## Description

desertcart.com: TOPPING HS02 USB 2.0 Audio Isolator, USB B USB C Input High Speed Isolation | Ground Loop Noise Reduction, Compatible with PCM32bit/768kHz & DSD512 Native, Up to 1500VDC Isolation, 50dB Noise Reduction : Industrial & Scientific

Review: A bit pricey but works very well. - I am using a Topping E30II DAC in my BRZ and was bothered by the digital noise i could hear during low audio passages. I connected the HS02 into the dedicated 5VDC power line feeding my Topping. The digital noise was no longer audible. Impressed with the performance but not the price. Its a bit on the costly side but it works.
Review: It works!! And removes whine from Nvidia 5090 FE edition card - I never post desertcart reviews but this one deserves it. If you use a high performance PC and hear GPU whine through your audio system, especially with an audio interface in the chain, this might help. This little product completely solved my issue. I run a powerful setup with a Motu M2 interface, Blue Sona mic, 2000W audio system with D class mono blocks, and a top tier AMD build with a 5090 FE GPU on an Asus board. Every time I scrolled in Chrome or pushed the GPU with work or games, the noise would show up. I was ready to swap out all my cables and even replace the PSU. Instead, I plugged this in right before the Motu M2 USB C input and the noise disappeared. Gone completely. Thank you to the maker of this product. You saved me hours of work and a lot of money.

## Features

- 👍 Fully Isolated Design ▶️ The HS02 has a fully isolated design, which does not introduce new interference when the auxiliary power supply is used while the audio signal is isolated from ground loop interference. Say goodbye to the ground loop and hum.
- 👍 Switching between two interfaces ▶️ The HS02 has two input interfaces (including a USB-B and a Type-C) and two output interfaces (including a USB-A and a Type-C), either of which can be selected by an input switch or an output switch. Note: Input is used to connect to the computer, output is used to connect to USB devices.
- 👍 High speed is also highly compatible ▶️ HS02 supports automatic identification of USB2.0 transmission at low speed, full speed, and high speed. The powerful transmission capability is compatible with high resolution audio such as PCM32bit/768kHz and DSD512 Native.

### ⭐⭐⭐⭐⭐ If you do not have Galvanic isolation, this is the ticket
*by D***N on December 26, 2023*

Digitally transparent, your PC or Mac won't even know this is there. I had the Intona Isolator, the pricier one not the cheapest one and it broke some of my DAC's ability to go over 24/96k. This works with all of my DAC's and allows full use of the resolutions on offer (including MQA and DSD). You may feel like it makes no difference if you didn't have "hum" or "buzz" or "noise" but if your DAC isn't galvanically isolated then this does make a difference. I notice because my powered speakers when set to full volume connected to my DAC as a preamp would hiss or have static. This was only at or near full volume. If I disconnected my DAC from my PC's USB and instead connected it to my phones USB (battery powered) the noise went away. In other words dirty power PC noise over USB was making it through. When I used my DAC to my headphone amp and headphones this was never audible. All the same once I put this between my PC and DAC the noise was gone and when using headphones it was even cleaner sounding with better spacial detail. I recommend these. Especially given how cheap they are. Though it's true, whether you notice the improvement or not will be system dependent but it definitely DOES do what it claims.
