I haven't really found anything on this but I am curious if anyone has done this with hi quality low noise resistors with different sonic qualities. With caps paralleling them may marry well together than if by them selves. Well this is what I'm planning to do. A shunt type 33 step attenuator calculated with Neville Roberts online resistor value calculator. Having Naked Z-foil for the series resistor. For the shunt I wanted to go with Caddock through out. This is were I wanted to play around with different resistors that might make an interesting combo. This could also give a more exact resistor value for each step and a specific percentage for the two in parallel. The Caddock possibly 60-70% and then the second being 30-40%. From what I've read of the Caddocks there give a very neutral sound with very good imaging. I've reading about the Amtrans and wanted possibly make them the secondary resistors. From what I've read they are very clean and possibly a little bright but a great sound stage with very crisp highs and tight base. I guess they don't act like carbons at all. I also thought the Shinkohs would be appropriate since they are have the sonic characteristic of being even balance though the full spectrum and also a fluid maybe tubbish sound? This would be a expensive experiment though. So if anyone could help me here I would be very great-full.
Well, I am not much into the flowery, descriptive language of sound. So, in tech terms: what is a fluid or tubbish sound?

I have experimented extensively with different types of shunt resistor and find any differences to be miniscule to the point of imaginary.
Even by having a 1:1 ratio? What about using different resistors on the same step? Thank you Don.
I built a ladder where every step was a different shunt resistor. Every shunt resistor was matched to the limits of my multi-meter. The only one that mattered was the one in the path.
