Preamp has too much gain

SPL Phonitor 2 Pre/HP also allow gain adjustments and is transparent zero coloration, you hear the actual source material. It is studio equipment. 

OP: 

Can you give us a little more detail?

Is the amp too loud or do you have too much noise?

If the amp is too loud a passive attenuator would work.  Having said that, there are many examples of preamps with too much gain, and therefore too much noise.

Which is you?

I had a preamp with a Goldpoint stepped volume pot with too much gain and installed Takman resistors on the pot and fixed the problem.

In-between the pre and power amplifier, insert another passive preamp ( without power), that let you adjust anytime in the future.

Hopefully after 16 years, he was able to figure it out.
