Customer Reviews (4.6 / 5 · 5 reviews)

William B. ★★★★★

The high-output version has exactly the gain I needed for my phono stage, and the detail retrieval through the mids is remarkable. Installed it last night and already heard nuances in old records I've played dozens of times.

Nicholas N. ★★★★★

Swapped to the low-output version for my setup and the difference in channel separation is genuinely noticeable. Instrument placement feels more precise than my old cartridge, and surface noise stays nicely in the background.

Steven ★★★★★

The low-output version really opened up the detail in my system, and swapping channels was surprisingly easy. Crisp, clear playback without any noise floor issues.
