steve, not that this matters to the OP but the traditional definition of a preamplifier is a control unit which includes a phono stage. Back in the 1980 with the emergence of CDs enough consumers abandoned LPs that the phono stage became redundant. So manufacturers responded by producing control units without built-in phono preamplifiers, they became known as line stages. Thus the Jumbo Shrimp is a line stage.
Of course all this led to much confusion over the years. ;^)
