With a foundation rooted in extensive research and expertise in live music, acoustics, and recording, Thivan Labs offers a diverse range of products, including speakers and tube-based electronics.
One of their notable offerings is the PH20, a tube phono stage preamplifier. This device is specifically designed to enhance the audio performance of your turntable by amplifying the signal with the warm and rich texture provided by the tubes. The PH20 features inputs for both MM (Moving Magnet) and MC (Moving Coil) heads, ensuring compatibility with various setups. Additionally, the preamplifier incorporates special output transformers that contribute to the reproduction of a clear and detailed sound.
The device utilizes a combination of four tubes, specifically two 12AX7, one 12АU7, and one 6SN7, in a single-ended configuration within the output transformer. As a result, the phono stage offers a gain of 46dB for MM heads and 66dB for MC heads. It features two inputs for MM and one for MC, providing flexibility for different setups.
Additionally, the device allows for load settings for MC heads, offering options of 22, 47, 100, 220, and 470Ω. This ensures compatibility with a wide range of cartridges. The signal is delivered to the output through both RCA and XLR connectors, offering versatility in connecting to various audio systems.
The PH20 phono stage, manufactured by Thivan Labs, is a substantial piece of equipment, weighing 18 kg. It boasts dimensions of 450x400x125 mm, making it a sturdy and sizable addition to any audio setup.
