This is still just a resistive attenuator.
What is the resistance range of the Silonex NSL-32SR2?
From the data sheet 0 ohms (40 ohm max) to 5 meg ohms.
So what is the output impedance?
Why would this sound better than any other resistive attenuator?
What am I missing?
"It is worth mentioning that the Lightspeed Passive Attenuator is not for every audio system though. First off, it is a passive attenuator so there is no gain. Also, your source output impedance needs to be less than about 100 ohms which makes it suitable for use with several sources. The Lightspeed Attenuator works best with amplifiers that have input impedance greater than about 50k. If you would like to use the attenuator with a low input impedance amplifier best results are achieved by using a suitable buffer between the attenuator and amplifier. "
