Product Summary
Stronger than time! This is the classic beauty in sound, admired by audiophiles for more than 60 years and will still be our top choice in the next 60 years. The legendary Siemens tone is considered the "reference sound" for serious classical listeners who need to upgrade the sound quality at phono stage.
Sound Characteristics
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 E88CC 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 E88CC tubes, Siemens E88CC's produce a warmer, smoother and more musical sound. To see how they compare to each other, please also see Soundlumia's exclusive Telefunken E88CC listings.
Professional Sound Evaluation
The pair worked wonderfully and sounded terrific in our professional studio setup for monitoring.
- Input: Cambridge Audio CXC V2 dedicated CD transport + Schiit Audio Bifrost 2 Multibit DAC

Our full tube sound review was written 100% based on the actual listening experience while this pair of tubes were running in the system described above.

This set was tested and certified by RoeTest V11 tester with the following result:
Tube 1:
Measured transconductance (GM): 14.59/13.24 mA/V - 117%/106% (100% = 12.50 mA/V)
Measured plate current (IA): 18.629/17.106 mA - 124%/114% (100% = 15 mA)
Tube 2:
Measured transconductance (GM): 14.57/14.04 mA/V - 117%/112% (100% = 12.50 mA/V)
Measured plate current (IA): 18.824/17.496 mA - 125%/117% (100% = 15 mA)
Tube 3:
Measured transconductance (GM): 14.21/14.35 mA/V - 114%/115% (100% = 12.50 mA/V)
Measured plate current (IA): 18.876/18.584 mA - 126%/124% (100% = 15 mA)
Tube 4:
Measured transconductance (GM): 15.23/14.64 mA/V - 122%/117% (100% = 12.50 mA/V)
Measured plate current (IA): 15.23/14.64 mA - 137%/127% (100% = 15 mA)
NO shorts, leakage or gas. NO noise or microphonics.
Curve trace is also included in the original RoeTest report.
Appearance & Cosmetic condition
Despite some loss of paint on one of the tubes, this pair overall is in great cosmetic condition. The 3-line Munich date codes etched on the glass are visible on both tubes although you may need to look closer to see them completely:
A3 7L (A = E88CC/CCa, 3 = Rev. #3, 7 = 1967, L = December)

- International Shipping: (Please read carefully) USPS First Class International is used for all countries EXCEPT: Armenia, Chile, China, India, Latvia, Mauritius, Mexico, Serbia, Slovenia, Tuvalu, and Vietnam. If you prefer to use a different carrier or shipping service, please contact us first so we can establish shipping rates before you make payment.

Soundlumia-sponsored 3-day guaranteed worldwide delivery program ($35 flat rate for ALL destinations in the world) via DHL Express is highly recommended.

- Combined shipping available - request invoice for total before making payment or receive shipping credit after order ships.
Return Policy - Please READ carefully
Returns are acceptable if we made a mistake by delivering you wrong or defective products. Tubes we sell are guaranteed to work because we run professional tests and sound evaluation TWICE: before they are approved for listing AND before we ship them to customers. So the "defective item" case doesn't exist and please do not bother trying - this type of returns will NOT be accepted without proof that tubes are faulty and we will open disputes with eBay. Sound experience is very subjective and we do NOT accept returns because you do not like the tube's sound signature or because you changed your mind about your purchase. Please contact us to work things out before submitting return requests claiming "item is defective" or "item not as described" or "just didn't like it" or "changed my mind."
Tube rollers abusing the return system will be reported to eBay immediately and negative feedback will be left to your account - that's guaranteed. 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 taxes/VAT/GST 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.
