“The Electroharmonix tubes significantly enhanced the soundstage and mid to high dynamics when added to the gain stage of my Freya + preamp. While there were modest enhancements to both when added to the buffer stage, they were much higher performers when added to the gain stage. They're also very quiet. Wouldn't hesitate to use these again.”

“Purchased two platinum cryo tubes. One of the two had a “lighthouse” effect the other tube stopped working after two days”

“The Electro-Harmonix 6SN7 made a significant improvement to the soundstage and midrange clarity on my DarkVoice 336SE headphone amp. Definitely worth the investment.”
