Slowhand,
I ve got them a year ago. I needed to wait a couple of years for them to be finished as I ordered them the period that Supratek wasn't on business. I believe today that Supratek is back on business it will not take more than a few months for them to get ready. I still feel that I could wait another couple of years every time I sit and listen them. They are masterpieces Also the option to remove completely the negative feedback, or to choose variable amounts of negative feedback with positive feedback makes them sound like SET (phenomenal mids and sound that floats in front of the speakers) and at the same time have the control of a SS amp on the lows. I honestly haven't heard anything that sounds better than these. Here is a photo of my setup:
