The STA-6 amplifier is derived from the Single End Class A Module + Class D design first introduced in the STA-9. By joining a powerful high impedance singled ended amplifier circuit in the preamp stage with a well integrated Class-D power stage, the STA-6 offers the richness of Class A sound with the remarkable speed and clarity of NuPrime Class-D design. Audio enthusiasts are bound to be impressed.
The NuPrime amp circuit improves on traditional Class-D design by using a self-oscillating circuit to generate pulse-width modulation. The amplifier switches at a frequency of 500kHz, well beyond the compact disc’s 44.1kHz sampling rate. Most class-D amps switch at 300kHz or lower. A new low noise switching power supply is designed specifically to complement the STA-6 amplifier. The overall result is unprecedented transient speed, smooth with lots of details and an almost shocking level of dynamic impact.
The STA-6's frequency response to 50 kHz elevates vocals into emotional experiences; similarly, instrumental upper registers mimic a live performance’s shimmering heights.
The STA-6 is designated for NuPrime Commercial product line and it is designed to be highly reliable under no-load condition and enhanced short circuit protection.
