Like Sondek implied, you need to factor in the additional gain afforded by your line stage, if you are using an active line stage.
Follow Ups:
Yes, active line stage with 17.9db of gain. Still a .25mv cartridge is not performing with it. I get plenty of volume but the signs of not enough gain are clear, lack of dynamics, no top end sparkle. Just trying to figure out for a new cartridge purchase what output I should be looking for.
You sure you've loaded it properly?
0.4 or 0.5 ought to be plenty of output, and there's bunches of carts to pick from in that range.
I'm prejudiced, but the Kiseki Purple Heart is a fantastic cart with 0.5mv output. Put it on your list.
I am kind of surprised that 57 db of phono gain plus 18db gain from your linestage is insufficient total gain for your cartridge to drive the amplifier. Most amps can be driven to full output by about 1V, give or take. Using an on-line calculator, I get about 1.4V at the standard stylus velocity, delivered from the output of your linestage to the input of your amplifier, from your 0.25mV cartridge. As mg16 suggested, you might want to check the input sensitivity of your amplifier, as well as your speaker's efficiency spec.I see JE posted almost simultaneously. He used 20db for the linestage; I used 18db. Either way, the audio signal coming out of your linestage is sufficient in amplitude to drive most amplifiers to full output.

What power amp are you using? You need to know its input sensitivity, given in volts, then you can calculate the cartridge output needed to drive the power amp to a reasonable output level to your speakers.
