Hi Chris,
Try a better one that uses a stepped attenuators or transformers. I fancy trying one of those Bent Audio jobs like the one Michaelab has. TBH there are other factors to take into account with passives.
Music wise, I have been listening to
Howard Tate - Rediscovered
Candi Staton - Candi Staton
Solomon Burke - Don't give up on me
Donnie - The Colored section
Soul music at it's best.
