HAS-33S High-End Dual Speaker / Amplifier Selector

Flexible Control, Absolute Purity. The Professional Solution for Multi-System Management.

The HAS-33S is a premium dual-layer selector designed for enthusiasts who demand both flexibility and sonic integrity. It allows you to connect up to three different amplifiers and three pairs of speakers, selecting any combination independently. Handcrafted in Japan, it ensures your high-fidelity signal remains pristine and unaffected by the switching process.

Key Features

• ■ Independent 3x3 Dual Switching
  Equipped with two independent rotary switches, the HAS-33S allows you to choose any one of 3 amplifiers and route it to any one of 3 speaker pairs. It’s the ultimate tool for comparing amplifiers or speakers without the hassle of re-plugging cables.
• ■ Precision Seiden Gold-Plated Switches
  Features two oversized (43mm) Japanese-made SEIDEN rotary switches. These professional-grade components utilize gold-plated contacts to ensure ultra-low contact resistance and exceptional reliability over decades of use.
• ■ Optimized for High Damping Factor
  Designed by amplifier engineers to minimize internal resistance (approx. 6mΩ). This ensures that your amplifier’s control over the speaker drivers remains tight and accurate, preserving the original bass response and soundstage.
• ■ Fully BTL & Tube Amplifier Safe
  The selector switches both the positive (+) and negative (-) lines simultaneously. This makes it 100% compatible with all amplifier designs, including balanced/BTL models, Class-D, and delicate vacuum tube amplifiers.
• ■ Robust Japanese Craftsmanship
  Housed in a sturdy 2.4kg chassis with a 4mm thick aluminum front panel. The two 40mm solid aluminum machined knobs provide a weighted, high-quality tactile feel during operation.
