Hey Bob,
I'd be sure that your tech has matched the the input impedance with the heads.
If the design of the preamp looks like it should have enough gain for the heads (50-60dB), it could be that a miss match is emphasizing the highs frequencies and bringing the hiss forward.
Measuring a frequency sweep should reveal that kind of issue.
