Cable connect to Harbeth 30 2.0


Turns out my Harbeth 30 2.0 XDs are showing up tomorrow. I thought I had some time to sell my Cardas Neutral Reference bi wires and start doing demos on my B&W CM 2s before I sold those as well. Can someone tell me if I can stack my high and low spades on Harbeth posts? Obviously it's not ideal, but I do need to make sure the speakers operate properly once I receive them. Otherwise, I'm going to have to order something cheap  I can get overnight like an Amazon Basics cable.
Thanks.

Got my 30.2 XDs today. I was able to get the spades tightened down well, and they sound fantastic.
Ctwith3 --- can you describe the sound of your new 30.2 XDs?  How are they placed in your room?  What stands are you using?  I just order a pair --my first Harbeths.
