Although they didn´t have much time to break-in, they already sound fabulous.... it´s unbelieveable!!!! Your description about these tubes on your website fits perfectly. Everything sounds so smooth, 3-dimensional and musical. I already tried a lot of tubes in the 6DJ8/6922/7308 family, but this one outperforms them all. This is one of the biggest improvements I ever had in my system. This pair of tubes is neither microphonic, nor noisy. It's a pleasure to deal with you!!!" Customer Comments: ----------------- "I think my favorite tubes for listening to my classic old rock/popular music are the 6922 Phillips Miniwatt "SQ" Holland because they are ultra quiet and have glorious highs to match their glorious low/midrange." Customer Comments: ----------------- "Thank you for your sending of E88CC Philips Miniwatt Holland. These tubes arrived safely and sound great. Actually they bring my system in much higher stage, like heaven. Quiet, smooth, dynamic and 3-dimensional sound. Music has become real. Always tubes you offer are nice. Hoping everything goes fine with you." Customer Comments: ----------------- "I purchased some NOS Amperex 6922s for a BAT VK-30 from you a few weeks ago. Just wanted to say thanks for your help. Now that the tubes are a little more seasoned, they have made a phenomenal difference in the sound of my system. The high frequency glare that I noticed with the Reflektor tubes is completely gone: highs have an extremely silky, fine grain structure. There is more air in the system: I sense more dimensionality in individual images, with greater silence between images. Midrange has a beautiful presence and palpability."

CCa: What is It? German Description: ------------------ Die folgende Valvo-CCa ist keine der "Gelben Serie" zugehörende, sie ist auch nicht tailliert. Es ist eine weiss gestempelte CCa die für die Post bestimmt war und auch entsprechend bezeichnet wurde. (Die Namensgebung CCa impliziert schon die Post-Zugehörigkeit, aber nur bei dieser wurde es zusätzlich auf der Röhre angegeben.) Sie besitzt den eingeätzten Code 7LH, darunter (Delta) 4D5. Die CCa ist eine Poströhre. Also eine speziell für die Post selektierte. (Besonders Rauscharm, Klingarm, besonders Langlebig.) "Klingarm" is the term for low microphonics. You often see Telefunken EF12K or AC701K, the K means Klingarm English Description: ------------------- CCa was a E88CC specially selected for "Post Germany"; special low noise, low microphonic, long-life 6922. Philips had similar selections for the "Dutch Post", some tubes are selected had "PTT" etched. The "German and Dutch Post" = telephone, telegraphie, telex, and the postal system. Much of the telephone centrals used tube equipment and for telephone equipment you want a "noise-free" enviroment. The letters "CC" probably equates to "double triode", and/or a for special design.
The Best Sounding CCa=6922 ever made TOP 5: ----- 1) CCa Siemens & Halske 1950's "U" getter halo and 1960's "O" getter halo "Rarest and most sought after CCa, has "gray shield" between plates, Most realistic sounding holographic soundstage, pure seductive sonic joy, complex symphonic images emerge effortlessly" 2) CCa Telefunken West Germany 1960's "excellent neutral holographic soundstage, vast vocabulary of tone establishes remarkable layers of harmonics, very rare" 3) CCa Siemens & Halske A-FRAME construction late 1960's - early 1970's "beautiful open air holographic images, low microphonic tube construction, rare" 4) CCa LORENZ West Germany early 1960's "beautiful open air holographic images, very rare" 5) CCa VALVO Heerlen Holland 1960's "real sonic holography, extremely rare" 6) CCa Siemens Rohre A-Frame early 1973-1974 (in stock, silver shield)
6922 with "GRAY SHIELD" 1950's - 1965 / "SILVER/CHROME SHIELD" 1966 - 1980's The "shield" is the "gray" or "shiny silver" plate (electrostatic shield) that is situated between the 2 gray dual triode plates inside a framed grid tube, such as a 6922, 6DJ8 and 7308. A "framed grid" tube is a high amplification(mu) VHF triode with a slotted frame around the grid to shield part of the grid structure and allow a controlled field of electrons to flow through to the plate.

I received them yesterday and put them in my dac last night. I thought I would just put them in and let them burn in a little for 24 hours and then listen a bit more seriously the next night. Well, I didn't! Instead I stayed up for a couple extra hours and listened to CD after CD. The difference these tubes made to the stock Sovteks is simply amazing. More open and airy, more detail and sparkle, and more control in the bass. There is just more there there without any coloration. The soundstage is wider and deeper and voices are more in the room. I would have never thought that these two little tubes would have such an impact in my system. I can't wait until they are fully burned in.

More space. Everything is better."

Very huge improvment over my old Mullard CV2493 in my DAC. Thanks for fast shipment and excellent packaging. - Igor" "I listened to the 8 x 6922 Telefunken yesterday with my LS5 ARC preamp, and yes, I have a Ferrari now, with the associated problems too !!! My room seems too small, the cables sound very bad (a room for improvement), and my neighbour doesn't like me anymore... To resume : I have very high definition, very liquid and smooth sound, deep and tight bass, large soundstaging, marvellous tones... I discover many details I never heard before and I can't stop listening whatever the kind of music. My amp is solidstate (the excellent D200 Gamut) but I have the impression the whole system uses tubes, except for the bass and dynamics. So, I discover that the preamp is a very important stage and the best tubes are necessary ! Thanks for the quality, you are the best ! - Frederic"

This seemed, to me, a large amount to spend on a single tube, but the testimonials on your site were so glowing that I had to find out if they were true or not. I bought the 6922 for my Decware SE84-CS stereo power amp, which I’ve been VERY happy with. It has a volume pot, so I don’t use a preamp---I run my CD player directly into the power amp. The SE84-CS uses a 6N1P, 6DJ8, or 6922 input tube, two EL84 (wired in triode mode) power tubes, and a 5U4-style rectifier. Mine had an early ‘60s Philips JAN 6922 that I thought sounded pretty good. (I had tried several other vintage input tubes, but none were as good as the Philips.) The difference with the cryo Telefunken 6922 was instantly obvious and nothing short of phenomenal---comparable to upgrading a component. A big jump in the amount of detail, much smoother sound with less grain, and more natural sounding reproduction with more realistic dynamics. E.g., Miles' trumpet (on Kind of Blue) had never sounded so good---so much like a real trumpet---there was some brassy "bite" that had been missing before. I noticed wetter cymbals, more intimate drum skin sounds, and way better horns---now Coltrane's sax really wailed. After several hours of listening, this one tube was giving me (i) much better handling of high volumes, (ii) much more involving sound, (iii) a blacker background, (iv) a better balance of frequencies (i.e., greatly reduced "shout" during shrill notes), and (v) a deeper, wider soundstage with a LOT more "air.” Everything you want, from one little tube. I can’t thank you enough. I am absolutely delighted with my purchase. Customer Comments: I listened to the cryo 6922 Telefunken pair yesterday and I am still wondering if it was a dream or not !!! Only the input stage pair has been changed out of the 10 of my LS5 ARC preamp (the others are still 6922 Sovtek). But the sonic performance of my system is unbelievable: I had a good car before, now I have a Porsche. All the areas are improved: smoothness, transparency, clear bass, wonderful tones, big soundstaging, it's magical ! What's going on if I change all the 6922 tubes ? Will I have a Ferrari ? I knew there was something wrong with my system before, but I was about to spend a lot of money on power conditioner, cables, bass trap and so on. Everyone who uses the 6922 Sovtek in a preamp should change at least the input stage tubes, the 6922 Sovtek is very bad...! Customer Comments: Brendan, you did it again. Your personal recommendations have always been right on the money. And speaking of the money I certainly got what I paid for. I paid a premium price and got a premium tube. I have listened to Telefunken and Siemens CCa tubes and some Telefunken 6922 Falcon Grade tubes and these Telefunken Cryogenic 6922s you sold me this week are by far the best sounding tubes I have ever heard. The dynamics are superb. They are so musical. I can't imagine using anything else now that I have heard these. I'm selling all my 6922's and CCa's that I currently have to buy that other pair of these you have. WOW! - John A." Customer Comments: I have spent thousands of dollars on equipment. Purchased noise reduction equipment, swapped equipment and tweaked equipment. I've done everything I know of to capture that elusive sound of real, live music. Never did I think I would find it in two little tubes weighing a couple of ounces each for $400 the pair. Yes, they are cryogenically treated, tested and matched, etc. but what do I care, I just want to close my eyes and be their in the recording session or at the live venue, transported to the real thing! This is it! You know all the adjectives already, so why bother. Bottom line, I have not found anything that even comes close to what these tubes can do to a system. They simply take you from good HiFi to the real event! My only regret, is all of the time, money and effort I have spent trying to achieve what these two little babies could give me for a mere $400. Do yourself a big favor give Tube World a call, spend the $400 or $500 dollars or whatever it is and enjoy the return on your investment. You can then thank me and you'll be glad you did! Rick (A satisfied customer who just happens to love music) Customer Comments: Many thanks for the 6922 Telefunken Diamond Bottom 1960's. I have done a lot of tube rolling for the last couple of months and I have changed and tweaked alot in my system. I have some of the best custom cabling. I have some of the best 2A3 tubes and some excellent 1940 6SN7 in my monoblocks, but the driver tubes in my phono preamp kept tormenting me. I have tried many: some of your Sylvania Cryo 7308. I have tried the Siemens Cryo. I have tried the Matsushita (a good tube!!). I have also tried some Brimar. None come close to these Telefunken. All the tubes I mentioned had something special about them. In some ways the Matsushita was better than the the cryo tubes. The Matsushita was more transparent. In my system the Sylvania was the lesser tube, too veiled. From all these tubes, the Brimar had pretty good transparency. All is relative: these tubes are no slouch, but still I missed something...But the Telefunken does probably everything better. The sound is purer. A deeper a wider soundstage and a superb sense of dimensionality. Most of all the Tele's prove the other tubes deficiencies. That is, a clean soundstage and a superb bass, but really superb. The improvement in bass was so noticeable that, what I thought was resonance, and to a certain point distortion, in the past, thus a sound too muddled, too distortioned at higher volume levels, was almost absent now. I still have to do something about bass traps, but with these Tele's, this "urgent" need became less urgent. It took me a long time to take this chance because these Tele's are far from cheap and I was hoping the last couple of days that these tubes would really prove themselves. They did!!!!!!!
