A photo taken this morning - on which you can see the grease mark to the right of the control knobs.
Although it doesn't spoil the sound, it just has to be got rid of.
You'll note the current flimsy Ikea table all this is standing on: the big piece of timber below is to take out an obvious sag of that bottom shelf - caused by the previous Cambridge & NVA. It will go eventually but the whole room is due work so it will have to wait (for now).
PS - here is the before shot that shows the NVA & Cambridge, together with my Technics SUV-303 integrated amp (that I used to determine if the lack of bass being experienced was due to speaker problems).
