Just a quick one on this.
I think I've just transformed my SBT from a mere 'convenience' music streamer into a serious High End audio stuff.
Thanks to the newly acquired Linear DC Power Supply.
YMMV but it made that oft use night and day difference to my setup.
Better 3D, increased realism and spatial details, bass and other what hifi style expletives.
In a word - It just makes my system less hifi sounding.
Would highly recommend all SBT owners to go the Linear way...I guess it's a sin if you don't.
