Ray Vacuum Tube 6SN7 Reserve


Apos Ray Tubes are now Ray Tubes--read about the rebrand!

The Best of the Best

The RESERVE Collection of Ray vacuum tubes are artfully designed and carefully manufactured solely for hifi audiophile devices. With the RESERVE, vocals are a revelation: smooth, lifelike, and beautifully present. They convey a sense of realism and immediacy without any bloat, offering a gentle yet compelling delivery with superior decay. The treble is crisp yet laid-baid, carefully balanced to avoid sibilance or harshness. This balanced sound signature extends to the low-end as well: full and commanding, contributing to an overall superbly realistic imaging that is brain-scratchingly good.

Engineered Exclusively for Audiophile Systems

Explicitly engineered for audiophile applications, the RESERVE Collection of vacuum tubes are crafted through a unique process that targets the specific needs of audiophiles, focusing on critical sound characteristics such as vocal realism, texture, and extended bass. Every aspect of their design and manufacture is aimed at enhancing the listening experience in high-fidelity systems.

Ensuring Excellence

Every vacuum tube in the RESERVE Collection is subjected to a stringent quality assurance process. An audio engineer personally assesses each vacuum tube against a detailed checklist that includes sound profile, dynamics, microphonics, gain, conductance, and noise levels, along with overall performance. This ensures not only that the vacuum tubes align with audiophile expectations for sound quality but also that they meet our rigorous standards for reliability and consistency. 

Gold Pins: Excellence in Every Detail

Gold pins not only add a touch of elegance but also serve a significant purpose. Gold's superior conductivity enhances signal transmission for crystal-clear sound, while its resistance to oxidation ensures long-term performance and durability. These qualities, combined with the secure contact gold provides within the socket, mean your vacuum tubes aren't just top-notch—they're built to last.

Silk-Screen Printed Logos

Even the logos deserve a special mention. Silk-screen-printed onto the tubes, they demonstrate Ray Tubes’  commitment to superior craftsmanship down to the smallest detail. This time-honored printing technique yields results that are not only aesthetically pleasing but also durable, ensuring the design work remains vibrant and intact over time.

Superior Sound, Secured

An exceptional 12-month warranty—a rarity in the world of vacuum tubes, especially NOS vacuum tubes—reflects Ray Tubes’ confidence in their vacuum tubes’ performance and durability. This warranty is your safeguard against any manufacturing defects, making sure that your investment is protected.
