Naim NAP S1 mono power amplifiers

http://www.naimaudio.com/statement

No Global Feedback

Sells was determined from the outset that the design would not use overall feedback. By breaking the feedback loop he could guarantee the speed of the amplifier would exceed what was needed to achieve the demanding new power levels and bandwidth. Secondly, by breaking the feedback loop the dynamic loading of the speaker is isolated from the delicate gain stages. The gain stages are then free and always working into a known load.

Three Stage Design

The NAP S1 power amplifier is a bridged design, which uses three short stages with only the first, the instrumentation voltage gain, using negative feedback. The second is an ultra-fast error cancellation system and the third is a unity gain high current output buffer. Each stage is optimised for only one task and the result is genuinely state of the art performance.

Naim 009 Transistors

To deliver the power with the performance targeted required a very special output transistor. Naim worked with the supplier of its already famous 007 transistor to produce a very special device, the 009. The 009 utilises Aluminium Nitride (ALN) - a substrate that has ten times the thermal conductivity of traditional Aluminium Oxide. In addition, the thermal paste used, to ensure good thermal conductivity to the heatsink is Nano diamond based. Diamond conducts heat 2.5 times faster than copper, as an example. The result is a transistor running with the maximum possible temperature stability for maximum linearity.
The power transformer of the NAP S1 is a huge 4000VA toroid using the finest grain orientated steel for maximum efficiency.
