The Classic Speaker forum Bob mentions also has forums for almost every other manufacturer of speakers. It makes good reading.

I just "recovered" a pair of Dynaco A-10 from the system of my late father. Other than fading of the walnut finish where one loudspeaker has been sitting in sunlight for 30+ years (cured by rubbing in brown shoe polish and buffing!), they're like they came from the factory. Dynaco and its Danish partners who made those speakers (and the classic A-25s, too) are to be commended.

yep... this Forum needs population... I believe it's max. 20 active people in there...
