Does the 250 not accept spades speaker connectors?
I have been happily using my new darTZeel CTH-8550 and PS Audio DirectStream DAC. The Devialet 250 has been in the closet for a few months.
I bought a pair of Audience AU 24e speaker cables. They are the most expensive but still not cheap. I got them with spades. They work perfect on the Dartzeel.
I pulled the Devialet out today as I was thinking about maybe getting the upgrade. I got my whole rack all resorted out to have two amps on it at the same time. I gave my Dartzeel and DirectStream a good listen. Then went to hook up my spade speaker cables to the Devialet and WTF....
Does this thing not accept spades? I then turned the speaker connector nut on the back of the amp all of the way out and now it won't go back on and I can't see how to use spades.....
My ever present frustration with Devialet is back almost immediately..... 
Any help would be appreciated.
