Nord One Value-Line NC500 ST Power Amplifier

Starting from


Our new Value-Line range of lower priced amplifiers. Built to compete with the budget box shifters offering a no frill amplifier with the same sonic performance of our standard range using the same modules. Incorporating lower priced cases with lasered front panel and no Aluminum feet. Lower priced binding posts and RCA connectors. No aluminum front badge.

The Nord One ST is our entry level stereo NC500 amplifier using one power supply. Consisting of amp module, PSU, Input buffer.

Using simplified input buffers (no Sparkos onboard regulators use supply from main PSU) with OPA1612 OP Amps all buffers have On-Board Switchable Gain 12.4-21.9-27.0-30.2 dB

Our Standard case is sourced from Italy and offers a consistent look across the range. We use quality RCA and XLR input sockets from Switchcraft in the USA and soldered directly onto buffer board no long input wire. Standard binding posts are 5 way including banana from CHK you will find these gracing the back of the £40K Ultima amplifiers.  The front main switch is finished in brushed stainless steel with an even blue halo LED. Our Nord badge is Aluminum and both this and the switch are neatly rebated. Which sits in our signature 3 parallel lines milled into the front of the case.  And they sit on solid brushed and polished lacquered isolation feet. Combined they produce a simple yet aesthetically pleasing look.

Moving inside the amplifier we build with a combination of quality and experience of laying out amplifiers in order to achieve ultimate performance. We balance this with ease of build in order to maintain lower prices without compromising quality. Vulnerable wire connections are double shrink sleeved to ensure long term reliability. We have recently moved to combine inputs directly to the buffer board eliminating long input signal paths.  Buffer boards are soldered using WBT silver solder. All resistors are either 1% or 0.1% tolerance where needed in the audio feedback path. Signal capacitors are ultra quite Wima Polypropylene while power caps are long life Panasonic FR range. Binding posts are connected to buffer board with as short a length of OFC Silver plated Teflon dielectric 14AWG wire. Neotech OCC option. The connections to the binding posts are crimped and soldered to ensure ultimate contact. Our SMPS have virtually zero noise emission’s an example of how this is achieved is attention to detail each power output transistor is individually wrapped in Copper foil shielding. We also pay a great deal of attention to Thermal testing when designing a new amp to ensure they run as cool as possible. Heat is the enemy and will reduce long term reliability.

All our amplifiers perform and offer far better value than any product available from dealers. Even our entry level MP range offer a base line of superb dynamics, amazing soundstage, clarity and sheer addictive musicality. Gone are any hints of the older Class D harsh and thin sound. They sound like the top notch Class A A/B amplifiers. Each amp is built by one individual who is responsible for its internal build quality.

There is no 40% dealer margin, no 40% distribution margin, no advertising or representatives supporting dealers to pay for. You buy direct from the us, the manufacture. We are free to source modules and parts from the very best (suppliers) in the world. Because of our low margins and overheads we can manufacture our amplifiers with the highest quality, expensive and  most reliable products available while keeping the cost low. It’s a winning formula and those that seek and take a leap of faith are truly rewarded with amazing sonic ability. We are passionate about our products and the way we look after you, in the highly unusual event of something going wrong. We loath the term (so called) Customer Service, we have all experienced that! What you get is to be treated as I would wish and expect to be – with directness and fairness, and I promise not to ask “Is their anything else I can help you with today”.
