No experience with either unit (though that Accuphase looks sexy as hell *thumbs up* for a conditioner - but I've been partial to the Accuphase/Luxman look), but it appears the Shunyata does some conditioning on it's own. You're essentially going overkill if you're connecting them in series, conditioning the incoming current twice (though you can still do that, if you really want to).
I'd hook in the Accuphase only, as long as it has enough outlets to suit your needs, and move the Shunyata over to a secondary. Or perhaps sell it and buy more music. :-)
