Hi Lu,

I just received the package today, thanks.

BTW, I haven't applied the power yet still busy building the case but by looking under magnifying glass I can see you've done a good soldering joint there...😉

bbp, Been using the R2r a lot, its a great piece of kit. My only gripe is the range with a relatively hot source.

are the 'steps' log or linear? component wise, is there anything i can do to give more control at the lowest volumes (-65 to 60 are big jumps).

For info, the attenuator is buffered (unity gain).
