SELECT Collection

A New Dimension of Sound

The SELECT Collection not only maintains the exceptional manufacturing quality of the CORE Collection but makes a significant leap in sound quality. Engineered for audiophiles who want an immersive auditory experience, this tier far surpasses what “factory vacuum tubes” can offer. 

Make Your Good Amp Great

The SELECT Collection significantly upgrades the performance of your vacuum tube amplifier, even starter models. These vacuum tubes are engineered to enhance the hidden capabilities of your amp, transforming its output into something far beyond its original sound profile. With each vacuum tube rigorously selected by our audio engineers, the SELECT Collection ensures a profound enhancement in clarity, texture, and detail. Every note resonates with more realism, every harmony carries more emotionality, and every rhythm pulses with tighter low-end precision. 

The SELECT Vacuum Tube Difference

Despite originating from the same batches as our CORE Collection, SELECT vacuum tubes are distinguished not by automated manufacturing differences but by the expert judgment of a professional. Our engineers assess each vacuum tube individually for its sound profile, dynamics, microphonics, gain, conductance, noise, and overall performance. This human touch ensures that only vacuum tubes that meet a superior level of sonic excellence are chosen. This meticulous, engineer-led selection is what makes the SELECT Collection exceptionally reliable and capable of delivering next-level sound quality.

Superior Sound, Secured

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