Siemens ECC82 12AU7 Chrome Plates Matched Pair - Munich 1961 Gf0

Description: Soundlumia's OpinionStronger than time! This is the classic beauty in sound, admired by audiophiles for over 60 years and will still be our top choice in the next 60 years. Particularly, the early '60s Siemens tone is considered the "reference sound" for serious classical listeners who need to upgrade the sound quality at phono stage. With the sound quality on par with Telefunken ECC802S (and even excel in certain areas,) Siemens chrome plates tubes competes strongly in the finest league of the ECC82 tube family, and is the sweetest sounding and most sought-after tube in the entire Siemens ECC82 series. And at what price again? The airy and transparent sound produced by these vintage Siemens tubes has been unrivaled even to this day. The magically extended yet never tizzy highs, coupled with the slightly focused upper mid-range, deliver a clear presentation of the entire frequency spectrum, completed by the precise and deep controlled bass. And the most defining sound characteristic of Siemens ECC82 tubes is their ability to retrieve the deepest levels of detail in sound, and these hidden sonic layers can go a long way to revealing the subtle ambient clues that help complete building a truly 3D holographic presentation. While as quiet and analytical as the best Telefunken ECC82 tubes, Siemens tubes produce a warmer, smoother and more musical sound.

We have already opened several dispute cases to report abusive buyers and eBay has always ruled in our favor. International buyers who request return or refund claiming your country's import duties or sales tax/GST/VAT are too high will be reported to eBay immediately for dishonesty and will be permanently blacklisted from purchasing from Soundlumia. We are committed to working closely with eBay to help rid the marketplace of dishonest, unjust, unreasonable, abusive buyers that are detrimental to the vintage tubes market and the audiophile community.
