>>. Is the goal to make the max output impedance match the max input impedance of the amp? If so, I can use a 10K series resistor.<<
The goal is to lose as little of your signal as possible, and have great dynamics and clean clear sound. This is a balancing act. We must try to keep several factors in balance. All at the same time. This is impossible. That is why you must have compromises. We must be skillful or we risk haveing an attenuator with poor dynamics, with lots of signal loss. I was in your shoes 3 months ago. I asked several very smart people what value my attenuator should be. I received several different answers!!! All I can tell you is what they told me: "I do not think the 15K values I received are a good match for my tube amp( 470K). Right? So what impedance value would you recommend?( My source is 100 ohms, my cables are short 1 meter. I realize that there is no perfect value for a pure passive attenuator. So, what would you recommend? 50k, 75K, 100K or should I just keep my 15K values. They do sound good".
Answer:
"Stick with the 15K attenuators. Best Regards, R. W."
So there you have my final solution, which would be considered a bit of a strain on my source, which is the Linn Linto phono preamp(100ohms). I ask Linn if the Linto would be happy driving this load, and they said it would be more than happy with this. So, now we are all happy here and the sound is great! Don't you just love happy endings?
