Does using XLR cables (double voltage output) mean I can use lower powered amplifiers?

Hi

Does using XLR cables (at 4V output from most dacs) vs RCA cables (with 2V output) mean that I have doubled the gain hence I only need half the power from amplifiers?

Just as a background I am looking for tube amplifers which typically are less powerful compared to solid state amplifiers. So I was wondering if using XLR connection rather than RCA mean that I can venture into lower powered amplifiers?

Or does the voltage input from the dac not matter/affect the power that a amplifier needs to drive the speakers?

Thanks!

Regards
Ben

ooh thanks! i always thought the gain is related to the power output! I guess you are right its different! was thinking if the power output is how much power you need to amplify the gain, and if the gain is higher, the final sound pressure for the fixed power amplification would be more.

I better go read up!

If you use  balanced connection on a low powered amplifier you will run out of power very quickly due to the fact that the preamplifier also usually has 6 decibels of extra gain also meaning that the low powered amp will run out o power usually before ten o clock on the volume knob.
