Excellent thread here!

Learning a lot on the trade offs between various topologies.

Iíll be following this closely.

PS even though the clicking is common in r2r ladders I believe it can be mitigated via software and/or other tricks.

Despite this drawback Iíve used this design in my system for some time and have come to view the clicking as gratifying.

Khozmo used to do one before their current model (which is now relay based with an optical encoder to control). And Bent Audio do an add-on kit for a few.

Seems like many people are coming up with different ideas for the volume control.
I did also, more conventional, digitally controlled volume, input, mute and IR remote.
