it does depend on the amp though, most amps will have a much higher SNR driving 2 than 4 or 8. The voltage drop across 2 ohms is much smaller than higher impedance drivers, with less of a drop the same noise will come across as a larger signal(thus the higher SNR). Granted it's not audible, but to an RTA you can tell the difference.
