RE: Disappointment with Rothwell attenuators

Those are obviously, not a serious kit, as they say. I made and sold the Ultimate Attenuator which was also a male to female adapter like the Rothwell but had a switch with fixed resistors attached to it to change the gain at will. They were, and are still held in high esteem. However, I never used them. Not transparent enough for me. The male to female adapter is not made from super materials. The Rothwell one looks totally ordinary. Also the resistors need to be the most expensive nude Vishays or you lose information and the impedances of the two resistors have to match the source and load. To this day, I use a nude Vishay resistor inside my amp and have the attenuator switch right next to each channels resistor to shunt resistors to ground to attenuate. I hear practically no sound to the two resistors, used this way. If I had a preamp with two much gain, I would mount two nude Vishays inside the preamp on the desired input. Damping the nude Vishays with a little EARSD40AL helps a little too.
