The soundstage representation is amazing.
I received my TPlus DAC yesterday. I just hooked-up the USB cable and powered the unit. Music started to play immediately. I am blown away by the sound quality of the DAC and it is probably not fully broken in yet.
The quality of musical instrument's timbre is very natural. The soundstage representation is amazing. Here are my audio system details for your study:
