Let me also post my small review of the BA-100: This is my first review, so please, keep it in mind while reading it :) Overall impression: Great product, high quality production from good materials and great sound with large stage and crisp clear highs and some smaller in bass and mid-bass...

Subscribed! Nice series!!!
