Best low-noise closely matched solution for your 12AU7 application. "... The 1960's Telefunken early ECC802S with klingarm Platinum Low-Noise AMPLITREX AT1000 TUBE MUSEUM CERTIFICATION represents 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"…
... "Their performance was off-the-charts in two separate listenings for this report. The bass is paradoxically liquid-tight sumptuously textured with all the low nuances the Double bass can give in a live-performance, yet full-bodied, and powerful. The midrange displays first, secondary, and third octave nuances, the tube has enormous layers of harmonic tonal depth, like a well weaved tapestry of sonic colors with pure gold strands woven into it's complex sonic-fabric, as well as a pouring out of liquid sonic lower, mid-midrange and upper-mid texture. The highs are liquid sweet like milk and honey, and pure as the crystalline morning snow and true to everything life has to through at it. THE VOCAL TIMBRE was compellingly superb, hauntingly realistic, like the singers were in the room with us, breathing every word. Very compelling tube providing absolutely no ear fatigue, or preamp adjustments, providing your speakers are placed correctly in your listening environment, and you have the audiophile-gear to appreciate it's capabilities."…

..." * Rp or plate resistance is the second most important parameter as it directly affects the output impedance of the preamp. Circuit designers are looking at Mu primarily, Rp next and we hardly care about Gm at all. Why then do most vendors measure Gm and Gm alone? Because most testers only measure Gm! No commercial tester ever measured Mu either (until the AMPLITREX AT1000 was introduced.) And even the Hickock, treasured for measuring Gm, doesn’t measure it meaningfully (due to current dependency), accurately (due to calibration difficulties) or consistently (due to internal circuit drift).'"...
