@handymann So you have a *different* preamp for the bass?
I think you would be better off running the sub off the main output, if the Aesthetix will support it.
The bass issue is understandable- I seek out original pressings on the older LPs, just because bass gets lost as more and more pressings are made. The liveliness of the recording suffers as well. That's why the original press often goes for more $$$. I think in cases like this tone controls might be helpful- for example when Mercury bought the recorders from Everest, they found an error in the EQ curve that causes the bass turnover to be off on a 6db slope starting around 100Hz. That's why Everest recordings can sound so great except for the bass. I think a similar thing happened with Westminster.
