What HFL Thinks

Naim NAP 500 DR Power Amplifier- Naim really are one of Britain’s truly great companies, always leading the way when it comes to hifi, whether it is creating the world greatest CD player to embracing this new age of streaming we find ourselves in today, but most importantly it always comes down to the music and nothing comes closer to recreating that infectious live sound than Naim. Please check back shortly as we write our thoughts on Naims extensive range.

Naim NAP 500 - The devil is in the detail.

Overview

As the debut product in our reference 500 Series range, the NAP 500 is a monumental expression of Naim amplifier technology. Its design was honed over six years of collaborative work with suppliers of specialist parts and each product takes days of dedicated assembly by our most skilled technicians in Salisbury. It’s this eye for detail, alongside its remarkable power, that allows the NAP 500 to bring your music into breath-taking focus.

New for 2015 – Statement technology 

Our flagship Statement amplification system was ten years in the making. The research and development project drew on all of our knowledge and expertise, yielding several breakthroughs in technology. Now for 2015 we’ve introduced two new technologies from the Statement project to our core range of power amplifiers. 

The NAP 500 now features the new NA009 transistors first introduced in Statement. In development for over a year, this key component was created in partnership with a specialist semi-conductor manufacturer to achieve the best possible sound quality. The 500 also includes the high power Naim DR (Discrete Regulator) technology used in Statement to provide the smooth, stable power supply we know is critical for the audio electronics to make music come to life. 

These two new technologies, combined with other small improvements to layout and componentry, mean the NAP 500 DR can produce even more of the fundamental musical pace, rhythm and timing that made the originals so popular with music lovers. 

Features

  • 140W per channel output into 8 ohms; capable of prolonged output into 2 ohms with no discernible impact on performance
  • Bridged power amplifier configuration for maximised open and closed-loop speed, with ten stages of local regulation per channel
  • Two-box configuration with 500 PS power supply for optimum rejection of electromagnetic interference
  • 1,100VA toroidal transformer provides 12 raw DC supplies for the power amplifier 
  • 25kg brushed, black-anodised chassis with distinctive heatsink plus variable speed intelligent fan system for discreet extra cooling if required

Technology & Craft

The NAP 500 delivers 140W per channel into 8 ohms and is capable of prolonged output into 2 ohms with no discernible impact to performance. Its two box configuration is classic Naim, with the power supply completely removed to the separate 500 PS power supply for ultimate performance. Each channel of the NAP 500 includes ten stages of local regulation. To reduce interference from the mains supply further, the transformer and first stages of the power supply are in a separate enclosure, the 500 PS, which provides twelve raw D.C. supplies for the power amplifier.

A bridged configuration allow for maximised open and closed loop speed, less intrusive protection circuitry and reduced interaction between input and output signals as the very high drive currents to the loudspeaker do not flow through the system earth. The NAP 500 also features an advanced output transistor, the 007, specifically designed for the purpose through months of collaborative work with a specialist supplier. The circuit topology has been developed to maximise bandwidth and reduce distortion and power supply dependency. Also, special attention has been paid to reducing thermally-induced noise, an especially important consideration in power amplifiers.

HiFi Lounge is proud to be one of a select few Bryston dealers in the UK who now come under the new Bryston Centre of Excellence initiative.

PMC speakers (Brystons UK distributer) are re-affirming their commitment to the development of Bryston for domestic use in the UK through the creation of a network of Bryston Centres of Excellence, PMC have appointed Tom Barron to the position of Bryston account manager, here is what he had to say about the new venture - account manager, here s what Tom had to say on the new venture -

"I will be working with a carefully selected group of retailers across the UK so we have strong geographical coverage that puts Bryston within easy reach of audiophiles up and down the land. Each Centre of Excellence will receive in-depth training to ensure they are fully conversant with all aspects of the brand, to enable them to serve their customers with confidence."

HiFi Lounge have been big fans of Bryston for many years now, owning much of their equipment personally before starting HiFi Lounge. We even started the always active Bryston Owners Thread on AVForums to which we contribute regularly, so it really is a privilege to be part this new scheme. We have a vast knowledge regarding the current Bryston range of which we have most on demo, so if you have any questions or would like to come in for a listen please do not hesitate to get in touch. There is nothing we like more than talking about and listening to Bryston equipment.
