Some good points made by Pim and Soniclife. It should be noted that the RIIA 1976 equalization standard includes a high pass filter, or "rumble filter". The RIIA 1976 is the default setting with the Devialet internal stage, and hence has the "rumble filter", but you can change to RIIA (not 1976) an lose the high pass filter. (not that you would want to)
I am not sure if you are aware, but if you go into the Devialet menu, through bass, treble, SAM etc, there is then a high pass filter option. If you are using a line input this is set to "none" as default, but you can used the remote to change to 2Hz, 4Hz, 10Hz, 20Hz, or whatever you need to tame the wobbly woofers. It is a very nice feature. I think the RIAA 1976 option is roughly equivalent to a 20Hz high pass filter, but you can fine tune this to suit your specific issue. After that, you can set SAM etc. to taste without worrying about the woofer issue.
As an aside, a while ago I tried an external phono stage and had exactly the same wobbly woofer issue, using the high pass filter solved this completely.
