HIFIMAN EF499 - Difuzor R2R și amplificator de căști de birou Streamer

Although at the beginning due to some health problems of the ear... I wanted to refuse this dac/amp, however I did not and it seems extremely good to me.
It has an extremely meaty, sweet sound, good refinement, good spatiality horizontally and very well vertically. Like the streamer, although it is simple, it still works very well, without problems.
The people from Muzix, very patient, serious. The amp/dac arrived faster than I thought.
Keep it up.
