Hi, Great Question, and very nice speakers.
I would call Egglestonworks directly (Jim Thompson is the President and is a really great guy). They are just getting back from a big show, so they may be a bit behind. But, I have always found Jim's counsel to be spot on- truthful, accurate and taking my needs into account when I chat with him. He has been with the company a long time, and takes the long-term view when dealing with customers. He knows their product inside out and can tell you what will match well with those speakers.
Hope this is helpful.
