Stereo Integrity SIQ 200.4 Amplifier: Purity and Power in Two Channels
The Stereo Integrity SIQ 200.4 brings true high-fidelity audio engineering back to mobile sound systems. Built by audiophiles for the most discerning listeners, this powerful 2-Channel Class A/B amplifier prioritizes signal integrity above all else. Its design features zero filters, zero crossovers, and zero EQ, delivering a full bandwidth signal (5 Hz to 150,000 Hz) that is clean, precise, and uncompromised. This is the foundation for an accurate soundstage and breathtaking sonic detail.
Uncompromised Audiophile Construction
Every component in the SIQ 200.4 was selected based on its acoustic performance and long-term durability:
-
Output Transistors: Utilizes audiophile-grade TO-3 output transistors for clean, linear power delivery.
-
Internal Circuitry: Features high-quality UPC4570 op-amps, IRFPO64N power supply transistors, and sand cast resistors throughout the construction.
-
Aesthetics: Protected by a thick extruded aluminum chassis with a copper anodized shielded transformer cover to minimize electromagnetic interference, all visible through a large plexiglass viewing window.
High Power, Ultra-Low Distortion Performance
The SIQ 200.4 delivers robust power with unmatched fidelity, validated by Audio Precision measurements:
-
