I have tried a few passives and the one that stood out was a music first tvc. It added a little body and bloom to the sound. Not like a tube pre but a little warmer than the other stepped resistor or variable passives i tried.
You just need to be ensure there is enough granularity in the volume steps but I imagine it should be fine driving the rogers.
not cheap, but a mint classic v1 can be picked up for a grand and there is nothing to go wrong!

Sorry but I dont understand what the Menu Tab is. The only options I see are Go to Topic Listing or Next Unread Topic, neither of which goes back to the spot I was at.
Can you please elaborate, thanks?
