[Last Updated - 18 June 2020]
Hi all,
Just compiled a list of some of the new potential portable DAC/AMP options in the form of USB-C dongles or USB DAC/AMPs yet to be reviewed on ASR, maybe can be a good reference for new releases / DACs to send to Amir. I am very interested in them due to smartphones removing the 3.5mm jack, and thanks to Amir’s awesome reviews I’ve purchased a Meizu Hifi Pro, Tempotec Sonata HD Pro, Zorloo Zuperdac-S and the good ol Apple Dongle, and also previously owned a iBasso DC02 and Tempotec Sonata II. Please forgive me for my very limited audio knowledge/any mistakes, just compiling some names, prices, key manufacturer claimed specs (I know a lot of manufacturers just use the chip specs though), and any other reviews/tests. Will try my best to keep this list updated, please feel free to contribute if you have anything. Thank you!

Hi all,
Just compiled a list of some of the new potential portable DAC/AMP options in the form of USB-C dongles or USB DAC/AMPs yet to be reviewed on ASR, maybe can be a good reference for new releases / DACs to send to Amir. I am very interested in them due to smartphones removing the 3.5mm jack, and thanks to Amir’s awesome reviews I’ve purchased a Meizu Hifi Pro, Tempotec Sonata HD Pro, Zorloo Zuperdac-S and the good ol Apple Dongle, and also previously owned a iBasso DC02 and Tempotec Sonata II.

Will try my best to keep this list updated, please feel free to contribute if you have anything. Thank you!
Notes:
- Ranked Alphabetically for both Dongles & USB
- Links I tried my best to only include manufacturers website only, however if I obtained missing information from a retailer site, the link was also included
- There a lot of new dongle DACs (many seem to just be cheap generic dongles) - I only included products from known brands OR products that I found listed on a reputable audio retailers OR products which have a good amount of manufacturer specs
- Going to only include 3.5mm USB-C Dongles & USB DAC/AMPs, so the device are all a DAC & Amp combo. Also going to exclude anything that has a rechargable battery inside (which excludes some portable dacs such as Topping NX4 & also bluetooth DACs).
- Any of my own comments/notes are italicised and included at the end
