About the 150

The Tube Audio Design TAD 150 Signature is a tube preamplifier designed for audiophiles seeking detailed and transparent sound. It supports four source components selectable via a front-panel knob or remote control. One input is a high-quality solid-state phono stage optimized for moving-magnet cartridges, with a switch to select between MM and MC cartridges. The signal path includes a tube line stage leading to two pairs of gold-plated RCA output jacks, allowing for biamplification or dedicated subwoofer outputs. The unit features a motor-driven Alps volume control isolated between triodes for fixed resistive input loads, a toroidal transformer power supply with two independent filter banks, and a headphone jack. The enclosure is a heavy, textured black steel case weighing 21 pounds. Setup includes a ground terminal and IEC-type removable power cord for easy upgrades. The TAD 150 Signature is praised for its ambience recovery, transparency, and sparkling transients, making it suitable for detailed music listening.
