Henrik’s Burson V6 Vivid Opamp with ASUS Xonar Essence STX

Published on

Post Info

I replaced stock opamps of my sound card, Asus Xonar Essence STX, with new ones by Burson Audio: 3 x dual Supreme Sound Opamp V6 Vivid. Results were improved clarity (without being crisp), much better separation of instruments (without losing any musicality), wider soundstage (without sacrificing intimacy). Bass is firm and substantial without being over the top and string instruments really sing. Thank you, Burson Audio, for your swift delivery of the superb Supreme Sound Opamp V6 Vivid!
