the top sonic echelon, 2 rare tesla special edition e88cc (6922) preamp audio tubes, musical transparent detailed warmth
these limited run specials will outperform most cca! w/ a true holographic live-concert level of sound reproduction
somewhere sonically in-between toshiba and a real lorenz germany (not sel copycats you see all over the net! skip those)
the breath of life, these telefunken tooled crown jewels are fan favorites that will replace 7308 pq amperex any day of the week
the mid-band is incredibly expansive and euphoric w/ no listen fatigue, and the bass drop is phenomenal w/ no roll-off
not to be confused w/ regular tesla that show up a bit harsh, these are lush involving and quite pleasant to listen to
vocals really shine w/ warmth, a vinyl style involving immersive footprint that is popular in preamps stereos and tube mics
the resolve is luminous + sparkley and the limited run internals are actually the highest quality you will find from the tube-era
try them in the position / application that sounds best to you
