It could be the quality of Gary' mains supply as an example.
I have been using a Musical Fidelity LPS phono stage until my own comes back from being reviewed and of course it uses a smps wall wart, my Isotek Sigmas has schuko sockets on the back so I had to plug the SMPS into a spare UK wall socket behind my rack, playing some vinyl all was well, when some schuko to UK adapters arrived that my wife ordered for our holiday I pinched one and plugged it into the back of the Sigmas and stuck the smps into that, beyond belief the improvement in the sound!
If you used a proper PSU for the bushmaster when you listened ignore the above! If you used a smps then it may be relevant.
