Can anyone help with a load of equipment I have acquired

The Joule pre-amp is a very high end item that was produced in limited quantities. There is a blue ok function on this site that may or may not have info on that item. The speakers are probably listed there. If you place a classified and have no other data, 50-60% of retail is not a bad place to start. 

To clarify what Swampwalker said, there is "Blue Book" feature on the website that is based on Audiogon sales.  This feature does have a cost, but it would well worth it in this circumstance.  I would also recommend looking up each piece in the search box to see if any are for sale.  You can also do this in eBay.  Sold items are the best measure, for Audiogoin you will need the Blue Book for that, but it is free on eBay.  Keep in mind that you may not get the maximum value since you are not familiar with the equipment and cannot fully attest to it's operating condition.  Savvy buyers will know when there is a degree of risk and will reduce paying price accordingly.  

You could also contact a Audio dealer who could sell for you. Just hope you can find a fair and honest one.
