John Atkinson's measurements of the overall gain (line stage + power stage) of the LM-518IA, as reported in Stereophile, are as follows:

The maximum voltage gain, measured into 8 ohms, varied with the output tap, but was appropriate for an integrated amplifier: 40.2dB (16 ohm tap), 38.6dB (8 ohm tap), and 36.5dB (4 ohm tap).Those are fairly typical numbers for the combination of a line stage preamplifier and a power amplifier, as well as for an integrated amp.
