Well, went to CostCo after payday to get a TSX-130. Bit of a warm, bassy, sound on CD and iPod - but DAB/FM reception was poor... Had previously a simple (i.e. cheap) transistor radio in the same spot in the kitchen which picked-up radio fine.
Borrowed a mate's Roberts DAB radio (again, only a small unit) and that was fine.
Tried all sorts of things with the aerial, it just did not work - plus missus thought it sounded a bit 'muffled' - so ended-up taking it back to CostCo, who took it back no problems. Shame.
Now waiting for delivery of an end-of-line Denon S52 to see how that goes.
