Exremely transparent and musical In stock form, it is above others of that price. The options of buying additional amp boards and modded boards is unique to this unit, and elevates it to TOTL level, without having to spend endless amounts of cash. I tried some others (n8ii, 3MaxSS&Ti, L&P6, AK200) so been around that "endless chasing", for the next best thing.
This is end game for me.
I have an 8k mostly Denafrips Home System, and this DX320 gets me more than half way there which is quite the statement. Huge powere, Huge Dynamics, very simple and effective EQ.. Outstanding Bluetooth connectivity and sound. I'd spen another $600 if you iBasso can widen the stage a little bit and work on imaging, otherwise I am a very happy camper. Super stylyish, and every amp module from tt - 13 have different sonics they can bring to the table. I'd place it above mid tier.. not quite god tier. This is the best value/quality at this price you'll ever find.
