This is an interesting solution for those who have capable players: http://www.monoprice.com/products/product.asp?c_id=101&cp_id=10110&cs_id=1011002&p_id=5557&seq=1&format=2
My Oppo 980H also silences the digital outputs with you try to play the SACD layer, but it will play the SACD through the HDMI output. This device converts that audio HDMI output to PCM which you can then put into your DAC. I'm sure there may be some stuff lost in translation, it's not ideal, but for that price it's a nifty solution. I haven't personally done it myself yet, but I do know that it works with my Oppo.
