NOS 1960 TRIODE-MATCHED PLATINUM LOW-NOISE PAIR

RATED ON THE TOP "BEST SOUNDING" E88CC EVER MADE


<>e Museum Tube Review "TOP 6"
 The following ubiquitous quote from the TubeMuseum.org Famous Review of the Best Top 6922 Audio tubes ever.
 
1) E88CC or CCa Siemens & Halske 1950's to 1960’s D getter or 1960's O getter halo "Rarest and most sought after CCa, has "Gray NOT silver shield" between plates and "Frame-Grid" construction. Most realistic sounding holographic soundstage, pure seductive sonic joy, Complex symphonic images emerge effortlessly"

2) E88CC or CCa VALVO/PHILIPS/AMPEREX Heerlen Holland 1960's "Real sonic holography, best-musicallity sounding, compellingly realistic, extremely incredible detail, warmth, and clarity - all at the same time, rated up there with the Siemens CCa, classified audiophile-extreme rarity, almost never seen or available in real NOS, especially in the most desirable HELEN HOLLAND tubes.
 
3) E88CC or CCa Telefunken West Germany 1960's "Excellent neutral holographic soundstage, vast vocabulary of tone Establishes remarkable layers of harmonics, very rare"
 
4) E88CC or CCa Siemens & Halske A-FRAME construction late 1960's to early 1970's "Beautiful open air holographic images, low microphonic tube construction, rare. Sonically Brilliant, Pristine, Musical & Therapeutic"
 
5) E88CC or CCa LORENZ West Germany early 1960's "Beautiful open air holographic images, very rare"

6) E88CC or CCa Siemens single stem halo early 1970’s “When you find a good pair they can be Fast & Accurate reproduction vessels of tonal tapestries. Excellent performance, smooth highs, outstanding 3-D holographic soundstage, lots of open-air, inner detail, and overall perfect resolution and balanced sound. Improved dynamics, frequency extension across the spectrum are immediately obvious, making the music sound much more accurate and real. A major improvement over other E88CC / 6922…"
 
“Audio tubes in general need to settle-in to the new environment, and get better with 'burn-in'. With the 6922 / E88CC you are going to hear ALL the frequencies passing through your system, the more sensitive the tube the more you will hear. You are using AUDIO GRADE tubes with the AMPEREX E88CC, which have a sonic-signature that reproduces not only the 'odd’ harmonics (1-3-5 etc.) but also the 'even' harmonics (2-4-6 etc.) The new tubes made today in China and Russia only reproduce 'odd' harmonics - that’s why everyone upgrades to a vintage made tube made decades ago when these rare 'earth-metals' were available in the inner construction of the vintage tube - now these metals are too expensive to use and today’s tube-makers have found cheaper substitutes which seem to work but do not reproduce all the nuances and textures in music. ..." The Tube Museum New York
 


…"You are using AUDIO GRADE tubes with the AMPEREX E88CC, which have a sonic-signature that reproduces not only the 'odd’ harmonics (1-3-5 etc.) but also the 'even' harmonics (2-4-6 etc.) The new tubes made today in China and Russia only reproduce 'odd' harmonics - that’s why everyone upgrades to a vintage made tube made decades ago when these rare 'earth-metals' were available in the inner construction of the vintage tube - now these metals are too expensive to use and today’s tube-makers have found cheaper substitutes which seem to work but do not reproduce all the nuances and textures in music."... The Tube Museum New York

…"The harmonics of an amplifier can be revealed in the distortion measurements.  There are two types of harmonics;  Even order harmonics and Odd order harmonics.  Musical instruments naturally create lots of Even order harmonics. So do single-ended amplifiers BTW.  However, I can't think of too many things in nature that create sound with Odd Order Harmonics, except for solid state and tube push pull amplifiers!  This is why you don't get an organic sound from these types of amplifiers, and why everyone is so gaga over Single ended designs. 

This works by simply playing a single tone at 1kHz and measuring the echo!  You can see that the first harmonic (A) is at 3kHz - an ODD number.  The next (B) is at 5kHz and the third (C) is at 7kHz.  This is what an ODD Order Harmonic signature looks like.  Notice there is no even order content whatsoever.  Also of interest is the average noise floor seen between the test signal at 1KHz and 20kHz is about -110dB.  (larger numbers are better). Considered very good this noise level is brought to you by a Balanced XLR solid state push pull power amplifier."...



…"One of the main reasons why push-pull amplifiers never sound like good single-ended triodes is because most push pull designs naturally cancel the even-order harmonics as clearly shown in the graph above! Below is the Zen TORII's graph, where you will find the missing Even order harmonics at 2kHz, 4kHz, 6kHz and so on, yet it IS a push pull design!"...


PRICE IS for the RARE HOLLAND MATCHED PAIR!

  The new tubes made today in China and Russia only reproduce 'odd' harmonics - that’s why everyone upgrades to a vintage made tube made decades ago when these rare 'earth-metals' were available in the inner construction of the vintage tube 


THE "TOTAL SOLUTION" is 1960 AMPEREX HELEN HOLLAND E88CC 6922 for proper "odd" and "even" harmonics reproduction

From the Tubemuseum Vaults - A REAL Archeological find … 1960's AMPEREX with VERY LARGE "O" Getter with Electro-Static Shield-Plates E88CC. “When you find a good tube it can be a Fast & Accurate reproduction vessel of tonal tapestries.

Audiophiles vote these as one of the best-sounding 6922 - even better sounding than Telefunken!  These tubes are known for excellent performance, smooth highs, inner detail and overall resolution and balanced sound.  Revered by many as one of the MOST DESIRABLE 6922 - the HOLY-GRAIL of the E88CC family and the MOST DESIRABLE 6922.  CERTIFIED ULTRA-LOW-NOISE PHONO-GRADE SPECIMEN - Manufactured in HOLLAND almost half a century ago!
