My problem:All to common, no need for a preamp with gain, try one of these for $49 and don't look back.
My preamp puts out 30db of gain and the output impedance is 1.2K ohms. My power amp input impedance is 22K ohms. I can only use 1/4th of the volume controls (9 o'clock) and it is too loud after that point. What would be the ideal output impedance for the preamp to mate well with the power amp? Components in question are an Audible Illusions Modulus 3B and an Odyssey Stratos Extreme+++. I would like to use more of the volume range and am open to a different pre.

And you can sent it back, if you wish, I doubt you will.

A Quote from the master Nelson PassCheers George
Nelson Pass,
We’ve got lots of gain in our electronics. More gain than some of us need or want. At least 10 db more.
Think of it this way: If you are running your volume control down around 9 o’clock, you are actually throwing away signal level so that a subsequent gain stage can make it back up.
Routinely DIYers opt to make themselves a “passive preamp” - just an input selector and a volume control.
What could be better? Hardly any noise or distortion added by these simple passive parts. No feedback, no worrying about what type of capacitors – just musical perfection.
And yet there are guys out there who don’t care for the result. “It sucks the life out of the music”, is a commonly heard refrain (really - I’m being serious here!). Maybe they are reacting psychologically to the need to turn the volume control up compared to an active preamp.
