1. Book: I wouldn't understand it. Not only that, it would frustrate me that I don't. It would also frustrate me that I don't have the budget to do more (more that costs $) I like technology but more than that I love the awesome and beautiful sound. I don't t really care about how the signals get to my speakers. Not in any disrespectful way, just I am not a nerd that way.
2. DAC Definitely! I am borrowing my brother's a test it out first.
3. New speakers. I don't have any desire to buy different speakers. I love the look and the sound. Of course if I won the lottery and saved all the orphans from Ukraine and had anything less, I would want the Martens.
4. I will do the photos. I will embarrass myself using West End cubes for speaker stands but. That's where they are.
