6922 tube
,, But not sure if my Cayin CD17 is sensitive enough to pick up these nuances,, I'm thinking glad i only paid $25 for a EH quad,, I don't like that design,, but when they arrive, I'll find out,,So yeah,, eventually i 'll save up for a pair of Tele's.. In this shootout I give the edge nuances to the Tele's. https://www.youtube.com/watch?v=nxPbvizQneU I will say this, more bigger nuances to gain via new caps vs new tubes. Tubes only make a slight nuance, whereas new caps, a medium size nuance. |
Subjectively, I prefer the cleanest, least colored sound, most 3D staging, most accurate tonality, I can get. The Germany and Dutch Post shared that preference (back when/probably didn't care about sound stage) and contracted, "specially selected" tubes, for their services. Make mine the early Sixties, grey shield, large halo, external date code, CCa. ie: https://www.tubemuseum.org/ProductDetails.asp?ProductCode=SH%5FCCa%5Fsingle Of course, as subjective and varied as listener tastes are; many absolutely love what seems to me the smothering warmth/glazed sweetness of the British tubes. The early Sixties Amperex that I've tried, weren't as warm, but still...... I understand: Different strokes and all that. When I had my shoppe, in Orlando, FL; I accommodated any and all tastes. |
Other than etched codes, stamped-internal-ID-plates & Telefunken diamond bottoms I learned to ID 6922 types by their internal construction. Japanese produced 6922 types are a bit tricky to ID as they used Amperex/Philips Euro parts and machinery, but there are subtle differences nonetheless. The stencil/label is the last thing I would use to ID a tube. You list RCA, which never manufactured a 6922 type, so what were they really? I've had RCA labeled 6922 type tubes that were manufactured by Siemens, Tungsram and Sylvania. If your GE 6922 types were not a smoked glass 6dj8 (the only 6922 type they ever produced) then what were they? Not familiar with your Cayin CD17, but would not use E288cc or the Russian 6H30 without checking with Cayin first. DeKay |
@motzartfan- Should you decide have your tube guy send samples to compare; these pages can offer ideas, far as what to request and sonics to expect: http://hktubeaudio.homestead.com/files/6dj8.html, https://www.head-fi.org/threads/6922-tube-review-17-top-6922-6n23p-e88cc-cca-7308-e188cc-tubes.76107... and: http://www.audiotubes.com/6dj8.htm |
