Ovidius B1. Realistic, that’s how I would describe this mysterious DAC/Amp. The overall sound reproduction meticulously focused on presenting transparent and natural sound. It is highly organic as it is competently technical. This B1 will reveal the nature of the recordings, any imperfections will be audibly heard. There’s no hint of attempts to overdo anything. This thing is totally uncolored. The smoothness level is just about right, the highs extended naturally, the lows oozes matured finesse, Mids naturally vivid – but it doesn’t feel out of place. What surprise me the most is how spacious and airy the sound is, the soundstage is wide as it is with proper depth – definitely among the best.

The greatest appeal for this Ovidius B1, is for those seeking perfectly balanced source – totally neutral and uncolored. In my book that’s a massive plus and I personally loved it. AND because it sounded so great with Extreme Metal, this B1 is definitely one of my personal favourites now.

PS: Would have received 100/100 score from me however I must factor in the cons as noted in Weaknesses – well nothing is perfect.


Recommended Pairing: Best synergy with technically competent IEMs and Headphones.
