Description
NuPrime audiophile quality commercial products are typically not sold in retail stores. Class A+D Stereo Amplifier (2 X 90W) bridgeable into a 160 watt Mono Amplifier. STA-6 is designed with enhanced even-order harmonic circuitry that produces sonic characteristic similar to NuPrime STA-9, but leaning toward neutral with a slight hint of warmth. The STA-6's spacious, transparent, dynamic and luxuriously textured soundstage has to be heard to believed. 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.

Product review & video
hey guys how's it going it's jay here and i welcome you back to another episode of take two on soundstage now this one was reviewed by doug schneider on june 1st 2020 so you can go and read it on soundstagehifi.com or by clicking on the link below the description he goes into much more detail than i will in this video but in this video i'll tell you my story with this amplifier so first things first this amplifier is not for you it's not for the consumers it is in fact to test out their purify module the class d amplifier module that they have and this is supposed to be sent out to different manufacturers who are potential customers to them in terms of taking in their class d module in their amplifier like the nad m33 that is going to be coming up for review very soon on soundstage take 2 here but this is really interesting because as reviewers doug and myself get to hear this and repor
