I Have heard and played a spaun bich kit and I thought it was a great sounding /playing kit,I have an Eames birch kit that I love,and the spaun sounded closer to it than anything I have ever heard,I think the main commonality is that both builders have a great skill and passion for what they do,along with using/making the best quality materials they can.
From what I understand uses a keller shell as a canvas,machines great lugs and hardware,puts a great edge on it,and does a great job finishing the shell acoustically and cosmetically.
From what I have seen the spuan kits bring a little more on resale outside the U.S.but the money spent on a spaun new,or esp used is well spent,and if I was going to spend money on a boutique kit spaun would be right at the top of all of them.
