Alright thanks for all the responses. In terms of the noise from the firebox: I'm going to try it out, and see how good it is. I'm going to hook up the phono and look at the noise I get through jamin - I think it's mostly high-frequency, so it shouldn't be to much of a problem after the RIAA curve is applied. If it's not working, I'll just run the signal through my stereo, which has phono inputs. All the other info is useful. Although using audacity looks easy, I think if the firebox works out I will be using ardour, probably routed through JAMin for the hdEQ. That way I can just stick in the CD track markers and go right to a CD. If I do this I'll make my .jam file publicly available somewhere so other people can use it too. That RIAA kit looks really neat. Maybe I'll have a go at it when I get some time. Thanks!
