I think it's certainly worth a go

It also doesn't seem that hard to get your head round either;

eg 'if' someone obviously has a room issue rather than their perceived cd player issue then wouldn't the right thing to do be to inform them this may be the case and in the first instance point them here?http://www.mhsoft.nl/Helmholtzabsorber.asp#PanelAbsorber

..for example, and maybe suggest there could be DSP solutions too?

ie advice without strings?
