Two questions:

I have a pair of Analysis Plus speaker cables that have banana terminations. The problem is that my MB Quart speakers don't have standard binding posts. Is there an adapter that will convert banana plugs to spades? I know this is not ideal, but it would be a lot better than crimping spades to my bananas, which is how I have it now (albeit not tightly).

Also, the included spikes on my Dynaudio 72 tower speakers are not long enough for the plush carpet I have them on and they are not heavy enough to push all the way through. The cement underneath also does not appear to be level, so I'm not getting a good solid footing. Where can I purchase longer narrow spikes?

Now if only I had settled on those Vienna speakers with the shot-lead fillable bottoms...
