Preamp output voltage...affect on volume???

I am in the middle of auditioning a new preamp which outputs 50 vrms max. My current preamp outputs 20vrms max. Assuming they are both pretty close in terms of gain and have the same number of volume steps (100 @ 0.5db each), does that mean the preamp with the 50vrms output will cause my sysem to sound louder than the 20vrms preamp (all else constant)? If so, how much louder?

thank you...

No, it wouldn't be louder. In fact, I am willing to bet you wouldn't even use any of the gain in either one! Many preamps don't need to be set past unity gain for the loudest music level used. Exceptions are preamps with post attenuators or those mated to a highly insensitive amp, like Newbee says.

It does sound like they have different gain. If you can't find the gain, you can also use the input sensitivity voltage to get your answer.

I seem to recall you can change the gain in the new Classe Delta preamps. I remember my old CP50 had this feature. It is a very practical feature to get the most resolution out of your volume control.
