You will struggle to get a nasty shock from 48 volts
Wikipedia... not exactly the gold standard, but why risk compromising safety to save 3 dollars?
"Voltages over approximately 50 volts can usually cause dangerous amounts of current to flow through a human being touching two points of a circuit, so safety standards, in general, are more restrictive where the chance of contact with such high-voltage circuits exists."
http://en.wikipedia.org/wiki/High_voltage
Approximately - 48V is approximately 50V - you would struggle to measure the difference on the 200V scale of an analog meter.
dangerous amounts of current - with at least 0.5A on tap there are dangerous ammounts of current in the amp.
touching 2 points of the circuit - like the grounded headphone jack and the heatsinks while plugging in/pulling out.
Spend the extra $3
