Hypersonic Mono

Ordered on the 15th of February and by 9th of March I did not receive any update, also tracking was not saying anything, not working correctly. After some email exchanges, they said the initial package got lost somewhere and so they sent another one which arrived in exactly 6 days, on the 17th of March which I appreciated tremendously!!! The Hypersonic Mono is amazing. Comparing it to Burson Vivid V6, the sound is more airy, more crispy, more dynamic, more punchy. The Vivid has a somewhat stronger subbass presence and warmer mids but loses in cleanliness, detail, transparency, speed, accuracy, dynamics, microdynamics, soundstage, 3D. Overall an amazing experience and I will definitely order again! Thank you! Later edit: the original order arrived 2 days after the one they remade and I asked for details to send it back. In return they replied: "Please don't bother sending them back and keep them either as spare ones just in case, or for yet another project or a friend in need ;) Just enjoy your music for now ". I have to say, the generosity and kindness is just out of this world!
