Update: I have re-uploaded RMAA scores that better reflect Alien's peak performance. The error was mine. Apologies.
Using the Shozy Alien is like being sentenced to opening child-proof bottles for life, but it sounds pretty good. Here are its RMAA results:
The following are the results of Rightmark Audio Analyzer tests.
Source: Shozy Alien
ADC: Lynx Studio HILO LT-TB
Computer: 2012 27" iMac
Cables: 1,5m Hosa Pro 3,5mm stereo to dual 3-pin XLR (around 8$)
NL - no load
SM2 - Earsonics SM2
ES7 - Audio Technica ES7
DT880 - Beyerdynamic DT880/600
Spoiler: it is nearly pointless to use the Alien for 24-bit audio.
Note: the wavy, horrible results are from maximum volume. Don't use it, even with external amplification.
