“The thing that puts [the Ray RESERVE 6SN7 tubes] in first place is resolution, bass control, and an overall tighter, cleaner sound compared to any of the NOS variety while still imparting a nice sense of tone and texture.” ~ Twittering Machines
“So what would the Ray tubes bring to the party? Well, definitely what I was getting was enhanced transparency. Inner detail, like the spaces between the instruments, that sort of thing. The bass had a little bit more kick to it.
Not tube-ier, not like softer, mellower. Not that kind of tube-y. This is tube-ier in terms of hearing deeper into the music.”~Steve Guttenberg, The Audiophliac
Customer Testimonial
“After more than 200 hours of burn in with the tubes, my read is that the LTA Aero DAC showcases a significant improvement in sound quality when upgraded to Ray Reserve tubes compared to the stock NOS GE 12SN7 tubes.
Ray Reserve tubes excel in delivering enhanced vocal realism, detailed treble, and extended bass. The result is a richer tonality over the stock tubes with a deep, controlled bass and a smooth, refined high end. They offer superior resolution, a tighter and cleaner sound, and a balanced tonal richness that creates an immersive and high-fidelity listening experience.
The improvements are so substantial that, if queried, I would say that purchase of either or both of Aero Dac and Mz3 should only be made with the upgrade to Ray Reserve tubes.”

Ray Tubes Quality Control Processes
Due to the clarity of the ZOTL circuit in LTA products, we are very picky about tubes. LTA has worked directly with Ray to establish strict guidelines and industry-leading QC processes to ensure great sound, consisent operation, and long tube life.
24 Hour Burn-In: Each tube undergoes a burn-in period to stabilize components and identify early signs that might lead to premature failures later on.
Comprehensive Parameter Testing: Tubes are tested against more than a dozen critical parameters like amplification factor and internal resistance.
Individual Measurement Recording: Measurements are logged under each set’s unique serial number for traceability.
Current Draw Analysis: Industrial-grade machinery measures current draw to ensure fully-accurate matching.
Functional Testing: Tubes are installed in amplifiers to assess real-world performance.
Microphonics Testing: Tubes are subjected to physical stressors to reveal any buzzing or defects.
Expert Listening Sessions: Audio specialists randomly select certain tubes that have passed all previous tests and evaluate the sound quality of tubes.
