Glad to hear you're liking the DI's as much as I am mofojo. Getting the wife's approval is huge! We will need to start a motor city DI club! The thread size is 1/4-20. I'm using the Mapleshade Heavyfeet carpet spikes and they not only couple the speakers to the basement floor well but are very stable, lift the speakers off the floor about an inch and look good.....the wife will like that!
Quite a jump indeed jetter. As good as the DI's sound I can't imagine the PMD's warranting such prices......but who knows, maybe they are that much better.
