Don’t know if this has appeared already?
I took part in some of the testing for the uHA-120, there were 3 different units with differences in the components in that test so I cannot give a full description of the sound of the final design. I have a good idea which unit most closely represented the final design as I got to speak with Justin who is the designer and gives the first part of his name to the brand.
Justin clearly knows his stuff and has big plans involving DACs and balanced designs, his enthusiasm for getting the very best out of these units is infectious – I have an iBasso D10 which I love but I have to say that the amp stage in theuHA-120 blew it away. The sound in general was powerful with a true feeling of accuracy, very detailed without oppressive at the top and deep smooth bass. I used Grado SR325is, Shure SRH840 and Ultrasone HFi780 worked well for all three.
The uHA-120 had a compelling sound but was also beautifully built feeling really solid with a reassuring weight which felt just right for the size, the casing and its printing has been really nicely finished.
Just Audios other amp is the AHA-120, a pure class A variant of the uHA-120 and they will also be offering some studio quality custom interconnects.
