NAD c370 owners: will the c370 accept 1/4" spades?

I can't really tell by looking, and I can't find the info in the manual or the website. Apparently there are three commonly used sizes of posts: 1/4", 5/16", and 3/8". Anyone know which the c370 uses? I have emailed NAD, but they are slow to respond. Thanks, Jb3
Don't know about size, and am not home to measure, but the heavy duty (WBT?) spades on my cables were too big, and I didn't want to reterminate to flimsier spades. I had to use adaptors, which are not easy to find.

Could you tell me where you got the adaptors? Thanks.

Sorry, I missed your question until now. I got them from the dealer, Lyric Hifi in NY, as a favor. I forgot who made them. I believe Monster Cable makes or made one also (the "Terminators"?) but don't know if they're still available. My best suggestion is to call Music Direct and see what they have. They're pretty good on parts.
