New Audio Note Niobium resistors

Audio Note (UK) new non-magnetic resistor are going. They are 2 watt, non-magnetic but rather than the usual Tantalum resistive layer its sister (daughter material, if you study Greek Mythology) Niobium was chosen. "Niobium has never been used in a resistor as far as we know. We looked at its properties and felt it was worth testing, and discovered that it is finer and more even sounding than Tantalum."

"As is the case with all of our resistors, they are manufactured using the sputter target process, which makes a much better sounding resistor but is also more difficult to use. Niobium is even harder to use than Tantalum as the temperature co-efficient of this material is far more difficult to control in production.

Its sound is very complimentary to Tantalum if used carefully in sound critical parts of the circuit. Price will be £19.50 each for the 2 watt version. We do not yet have the 1 and ½ watt versions as the manufacturing processes are still under development, but there will be a 2 watt silver Niobium resistor coming next."

We will have the following values available: -

100R, 120R, 150R, 180R, 220R, 270R, 330R, 390R, 470R, 560R, 680R, 820R
