Consider the following:
Using a passive attenuation device requires that you optimise electrical "energy transfer" parametres (between pre & amp)
1) The output impedance of the pre and the input of the amp are important. The placette seems to have a reasonably low output imp and reasonably steady across the audible spectrum -- and this helps.
2) The source component (i.e. whatever precedes the "passive" pre) will be driving: wire-> volume control (passive pre)->wire->amp. So it must have a strong output.
3) Softened bass is usually the sign that insufficient energy is entering the amp -- it has to do with the source, the impedances of the amp & the attenuation device (passive pre).
4) If you know the input impedance of yr amp & the output specs of the Rogue, you can guess what the results would be. Or, you can try it.
