Well not really issues...

I just got my new preamp in (Herron HL-1) and it seems the gain on my D-100's is too high. Is there anyway to fix this? I thought i had the 26db version of the D-100's and the Herron has 14db of gain, which isn't that much?
I've seen people using their Ciaudio D-series with pre's like modwright, which has an even higer gain (15db). So I can't really grasp this... O yeah, why I think the gain is to much? Because I can still hear the music with the volume on zero and it's get really loud really fast.
I just ordered Rothwell attenuators as a temporary solution, but I'd like to know if there's a better way round this.
Greetz,
