I better say hello first being new here, how are you all doing. I have a quick question for you all. I managed to listen for the first time a pair of Castle Durham II Speakers and to my surprise was absolutely blown away by there performance for a bookshelf speaker. The speaker where being run by a pair of Quad II Monoblock Valve Power Amps. It turns out that these speaker stop production some years ago know and I was hoping to buy a pair but cannot find them anywhere online. Are these speaker a keeper and do not come up for sale very often, or am I just not looking in the right place.
