Yeah, but what's actually clipping -- the recording itself, or the input stage of your preamplifier? That's the real question you must answer. Most preamps can handle 4.5volts without clipping, but a few may not handle it gracefully...
What is the CD player plugged into and what is its input overload rating? You might need to consult the manufacturer of the preamp (or amp) on that point. Manufacturers don't always include that specification.
