About the NuPrime Evolution Two-SE
The NuPrime Evolution Two-SE is a mono power amplifier rated at 300 watts RMS into 8 ohms, with THD+N of 0.001% at 5 watts and NuPrime's Only Distortion Cancellation (ODC) Class D design. NuPrime describes it as the most powerful, dynamic, natural and detailed amplifier in its lineup. It is built to drive 2-ohm loads, and a stereo system uses two. At HiFi Boutique it ships free anywhere in the USA, with sales tax already included.
Why Choose the Evolution Two-SE
Most amplifiers correct errors with global negative feedback: they invert the output, compare it to the input, and correct the next cycle. NuPrime's ODC design instead takes its error signal directly from the MOSFET devices and output filter, which reduces the amount of negative feedback needed.
Compared with the Evolution Two, the SE has a new ODC circuit that NuPrime says handles interference ten times better, lowering THD+N from 0.003% at 5W to 0.001%. New Class D power MOSFETs give three times the peak current, and military-grade feedback resistors with a 15ppm temperature coefficient, improve resolution.
NuPrime describes the sound as an expansive soundstage over a deep black background, with authoritative control of low-impedance speakers and a warm tonality reminiscent of Class A.

FAQ
FAQ
Is the Evolution Two-SE a stereo or mono amplifier?
It is a true mono amplifier. A stereo system uses two.
How many watts is the Evolution Two-SE?
NuPrime rates it at 300W RMS into 8 ohms, with 410W peak.
Can the Evolution Two-SE drive 2-ohm speakers?
Yes. NuPrime lists 2-ohm load compatibility, supported by 48,400µF of power supply capacitance and new high-current MOSFETs.
What is ODC?
Only Distortion Cancellation is NuPrime's Class D design. It takes the error signal directly from the MOSFETs and output filter which significantly reduces the negative feedback required.
What changed from the Evolution Two?
A new ODC circuit, lower distortion (0.001% at 5W versus 0.003%), new MOSFETs with three times the peak current, precision feedback resistors and a CNC-machined heatsink module.
What warranty does the NuPrime Evolution Two-SE have?
NuPrime lists a 3-year manufacturer warranty for the Evolution Two-SE.
Does HiFi Boutique charge shipping or sales tax on the Evolution Two-SE?
No. The Evolution Two-SE ships free anywhere in the USA, and sales tax is already included, so the price you see is what you pay.
