DIY Stepped Attenuator – audio at home
https://audio-at-home.com/diy-stepped-attenuator
DIY Stepped Attenuator. This project came in as a logical end of a continuous process of refining the amplifier’s performance. The itch to check out how a stepped attenuator will perform against the ubiquitous volume potentiometer became increasingly acute after the surgery that transformed my Audio Note OTO Phono SE Signature integrated into a P1 SE …

The best stepped attenuators I've seen are the dual mono kits from Michael Percy. www.percyaudio.com. He uses a great quality 45 position Shallco rotary switch (not made any more) and Holco resistors. Ladder L type. The signal only passes through one resistor. You specify the impedance. Not cheap but still a good value. $275 US. •••

Mark Tillotson. 11 steps is not going to be enough without a separate range switch - for instance one switch in 10dB steps, one in 1dB steps could work. That does mean having active buffering between the stages though. And there is inevitably some compromise to be made with noise floor and headroom with a 2-stage volume control of any form.
finally, a stepped attenuator | DIY Audio Adventure and Others
https://vwws.wordpress.com/2008/02/12/finally-a-stepped-attenuator/
it took some time to understand which resistor value pair goes where for that ladder stepped attenuator. i saw a posting on echoloft selling a used DACT CT1 50k stepped attenuator and did not hesitate in getting it. the CT1 was installed onto the 5687 preamp last night. i had to drill a larger opening for the shaft to be put in. i also had to ...
DHTRob - A DIY series stepped attenuator (1)
https://www.dhtrob.com/projecten/stapp_schakelaar1_en.php
A DIY series stepped attenuator (1) Go to page 1 2 3. Stepped attenuators are ready available and come in two different kinds: Series stepped attenuator. Here are the resistors mounted in series. In using a switch a postition between these resistors is chosen which determines the total attenuation. Disadvantage is that all resistors used are "in signal" (to ground).

Once I considered the Customs and all the associated fees, it wasn’t as cheap as I wanted it to be. Then by my favourite method of discovery, by chance, I discovered the Audiopills Stepped Attenuator. At £65 delivered it seemed too good to be true, but it’s use of Tesla resistors made it my primary target.

https://www.instructables.com/Homemade-RCA-Attenuator/
Homemade RCA Attenuator: This project arose from the fact that I had too much gain in my audio system, and I needed a practical solution without modifying the PCB circuit. The problem can be solved using an RCA (in-line) attenuator, but since a new one can be quite expensiv…
The δ1 relay-based R-2R stereo attenuator - AMB
https://www.amb.org/audio/delta1/
δ1 ("delta 1") is a high-end stereo stepped attenuator implemented in a R-2R resistor ladder topology. It uses high quality miniature latching relays and precision discrete resistors to achieve a level of performance unattainable with conventional potentiometers or mechanical switch-based rotary stepped attenuators. δ1 is designed to be controlled by the LCDuino-1 Display I/O …
