Review: Coming from a FiiO D3 I'd say this is a really good upgrade. The sound quality is fantastic, I can't imagine anything sounding noticeably better. The feature set is also really nice, especially the auto on/off and pure dac features. I'm using the optical toslink input with a mac mini running debian Linux and the Logitech media server software. From this I play local flac files, CDs, and hi-res music from Qobuz and I really couldn't be happier with the results. I did want to use the USB input instead of toslink but the auto on/off doesn't seem to work in this mode, but that might be because of how the USB audio output works on my setup. Overall I'm happy I bought this and I would recommend it to anyone looking for a high quality dac. EDIT: Still using and enjoying this DAC. Just wanted to update that I found a way to get the auto on/off working on Linux when using USB. Using the lsusb command I got the idVendor and idProduct of the DAC. Then you edit/create the file /etc/udev/rules.d/90-usb-power.rules and add the following line: ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="152a", ATTR{idProduct}=="8750", TEST=="power/control", ATTR{power/control}="auto" Those numbers should be the same for you if you have this same DAC so the lsusb part can be skipped. After that I rebooted the system and then the DAC was able to go into standby via USB.
Review: The Topping E30 ii DAC definitely improved the output quality of music from my Lenovo Yoga laptop. I store all my digital music in lossless format, I don't use mp3's due to the compression & lossy algorithms. I really appreciate being able to get the best out of my music collection & the Topping does just that. I realize everyone doesn't feel the need for the highest quality music reproduction, to some storage space is a concern. But if you're someone with a keen ear & an audio system that reproduces the fine nuances many of us appreciate & demand, a unit like the E30 ii is well worth investigating. I wish I could rate it 4.5 of 5. 5 for quality of reproduction & ease of use, with a small ding for the setup process & supplied documentation.

## Features

- 👍 Supports high-resolution audio ▶️ TOPPING E30 II uses two sub-flagship AK4493S chips of AKM's VELVET Sound technology. AK4493S is an upgraded version of the previous AK4493. Two AK4493S in parallel can achieve better performance and reduction ability than a single chip.
- 👍 Coaxial and Optical also has good performance ▶️ The optical and coaxial input of E30 II supports up to 24bit192kHz audio, which is suitable for digital turntables, disk players, set-top boxes, and game consoles, so that traditional equipment can also give a new sound. The Digital Processing module provides better compatibility than the E30.
- 👍 5V power supply,anytime and anywhere ▶️ E30 II uses DC5V for power supply, which can easily access almost everywhere. You can power it up by USB port of PC, mobile phone charger or even a power bank. The built-in protection circuit will protect the E30 II and prompt on the screen after connecting to the wrong power supply.
- 👍 Discrete LNRD ▶️ How to solve the noise problem of 5V power supply? The E30 II's answer is the Discrete LNRD circuit (low noise reference driver). The Discrete LNRD circuit filters out the noise of various 5V power input and provides stable power supply of ultra-low noise reference level for E30 II. With this technology, the noise floor of E30 II is lower than 1 .5uV.
- 👍 Pure DAC & DAC+Preamp application ▶️ E30 II is able to fix to maxmum output level so that it can be worked as a pure DAC. E30 II has built-in volume control function that can adjust the volume from -99dB to 0dB by using the remote control, so you are able to directly connect E30 II to power amplifier or active speakers, and control the volume of E30 II through remote control.

## Questions & Answers

**Q: how about the warranty?**
A: APOS has been fantastic with any issues that have occurred.

**Q: Tengo la aplicacion tidal en mi tv lg. cuando conecto el tv al dac por cable optico, solo se muestra 48 khz de frecuencia de muestreo y no 192 khz.**
A: Hola.
Yo uso el DAC para oir musica, conectado al servicio de música de Apple. La mayoria de discos vienen en formato 44.1 KHZ, algunos vienen en 96 KHZ y muy pocos en 192 KZ. El DAC automáticamente muestra la calidad en la cual está la fuente.
Seguramente el muestreo que recibes es en 48 Khz.
Habría que revisar si el streaming ofrece calidad superior.

**Q: does this work on Xbox series x ?**
A: I'm not an X-Box user, but the Topping E-30 has inputs for both SPDIF coax and optical, as well as USB input. If your X-Box outputs any if these formats, it should work.

**Q: is the usb plug and play with a phones otg cable?**
A: You can use it via usb on your phone but for portable use you need a power source for it.

I have a $3,500 Cambridge DAC and I would say the Topping E50 is very very close in sound quality to that DAC - I’ve already recommended this DAC to my friends. Thanks
