Jack has asked me to do a comparison project for Woo Audio's new website that is coming shortly. I will be writing summaries for each amplifier and other Woo products for the website. I am very excited to be participating in this project and have enclosed some pictures that Jack took while we were setting up all the gear in my house. I will post updates and share some of my thoughts on this thread as I am going forward. The summaries will include descriptions of all the products and what headphones will work best with each product and also their will be a summary of the Digital to Analogue Converter as well. This is and fun and exciting project .
