Naim Audio NPX TT power supply is an upgrade to the power supply for the NVC TT phono stage. It has dedicated sections for digital and analogue and will provide the best possible power source for this excellent phono stage.
Firstly, a large transformer is used for good transient response. The separate feeds for the digital and analogue circuits prevent any mutual interference. Finally, Naim uses their own DR power design that outperforms other designs.
Why a separate PSU?
Using the NPX TT power supply to drive the NVC TT preamplifier should remove any possible sources of magnetic and mechanical interference. As a result, the sensitive internal electronics can work at their best. The upgraded PSU also separates the digital and analogue power feeds. This prevents any interference from crossing over between sections.
Power supplies use large mains transformers, that generate both mechanical and electrical noise. With a separate PSU, this is moved away from the Audio signal path. Moreover, noise from the rectifiers can also get into the grounding system adding mush and interference to the sound. As a result, Naim has developed their own power supply design, known as DR or Discrete regulator.
The Naim DR power system
The Naim DR power system is used throughout the range and gives a stable and clean output. It may seem simple to design a power supply but several factors complicate the issue. For example, many different voltages are required for different stages. Moreover they can mutually interfere with each other. The signal from a turntable phono cartridge is very fragile and noise can affect the sound if not controlled. Hence the NPX TT has dual supplies. Cheaper units can use monolithic voltage regulator ICs. These are convenient but can be unstable and have limited output current capability.

Testimonials
Bought some Rega Kyte speakers, stands and chords from DB online and they were incredibly helpful. They updated my delivery address very quickly and recommended a longer cut of cables which they did complimentary. They also noticed I didn’t order with banana plugs so called me back to double check, which I did mean to order. When i had some issues connecting my cables and speakers, I called for some advice which they happily gave. Excellent service and next day delivery to London. Thoroughly recommend.

Probably one of the best companies in the world. They had to special order in the speakers which took a fair bit of time, which is totally understandable, but they kept in touch with me throughout the entire time with updates (even on a Sunday!!!) and once the speakers were with them, they were dispatched and arrived next day.
The entire sound system that I purchased is insanely good, but still not as good as Doug Brady HiFi!

I have recently purchased a HiFi package with Doug Brady and I could not be more thrilled with my experience with them.
When I walked into the store, I was made to feel welcome and was introduced to some of the products. I produces a list of specific items I was interested in and John was really helpful in showing me these items. He set the system up so I could experience it, he made some suggestions which made the package even better. Nothing seemed too much trouble for him, he was very knowledgeable about the products and gave great advice. I didn't feel pressured to buy anything, or didn't feel that he was upselling at any point. I left with an amazing package and I'd like to thank John and the team for the fantastic experience.
