SIQ 75.4 (Class A/B)

Description

Hi-Fi class A/B and class D amplifiers are back with our SIQ amplifiers. Full bandwidth, zero filters, discrete gain knob per channel, zero crossovers, zero EQ. Purity at its finest. Being avid audiophiles for over 25 years we have always appreciated the finer performing amplifiers in mobile audio and with our growing presence in the mobile audio industry, we have been able to team up with talented amplifier engineers and finally produce our own hi-fi amplifiers. Audiophile components were used throughout construction and engineering to bring our amplifiers to fruition. And because we are a direct company (no dealers) the cost savings are passed directly to you, our customers.

All of our SIQ class A/B amplifiers utilize audiophile-grade T0-3 output transistors, clean board layouts, thick extruded aluminum chassis, copper anodized shielded transformer covers, and a large plexiglass viewing window. Coming inward we use UPC4570 op-amps followed by IRFPO64N power supply transistors, sand cast resistors, surface mount parts to save board space, and Tiffany-style RCA connections. All of the above FR and power graphs are from Audio Precision measurements.
