Telefunken ECC802S the "Holy-Grail" of all 12AU7/ECC82 SINGLE tube.
..."ETHEREAL CONDUIT TO A HIGHER REALM"  ..On the other sonic-side lies the realms of musical-ideals, dream worlds, and the sonic-heavens and havens of different tube-religions. Telefunken ECC802S can be the conduit to outer sonic planes or sonic-astral realm".... Tube Museum.
Best low-noise closely matched triode single tube solution for your 12AU7 application.
"... The 1960's Telefunken early ECC802S with  klingarm Platinum Low-Noise represent the full expression of Telefunken's best achievement for a 12AU7WA / 6189. The richness of the music reproduced surpass any other previous attempt of any other tube ever made. While listing to Miles Davis SKETCHES OF SPAIN with Gil Evans I can hear, see, and feel Miles sitting on a stool in a section in my listening room, a trio of trumpet, trombone and flute behind him. 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! "Miles above" and Simply beautiful and well worth the price for the ECC802S 'klingarm' factory tubes!...worlds better than the newer commercial series by "miles"…
