Sonics
Considered by audiophiles the HOLY-GRAIL of all 12AT7/ECC81 tubes! The richness of the music reproduced surpass any other previous attempt of any other ECC81 tube ever made. “
Cit. “As if the members of the band are right in the room with you! The dense textural details and markings for dynamics are performed precisely as recorded and reproduced so that all the interweaving parts emerge clearly. The depth of musical emotion is distinctly audible with every detail of the pure orchestral fabric as I’m not hearing my preamp, amp, or speakers anymore, just pure music, the conduit to a higher musical realm, as if there is no hardware at all!”
