Will post you review here? I think a lot of headfiers would enjoy the read and the sound comparisons of Pro iESL with all of those headphones. I also have the iDSD BL and find it an incredible piece of gear as well.i must admit I wasn't familiar with iFi until I joined Head-Fi. Now I'm a fan for life. I can't wait until the Pro iDSD gets released so I can complete my Pro Series stack.
