...the A70s were my first decent speaker. My friend recently gave me a pair of near-mint A100s, and that's part of my bedroom rig now. I bit the bullet and bought new replacement woofers from BA. They have sonic problems "fer sure", but they can be quite dynamic and always easy on the ears. I do, however, think I need a smaller stereo in here...

What's odd is Boston decided to do the offset tweeter thing in some of the later series.

The top-dog A400 was the cat's pajamas to me at that time - I wonder how they would stack up now.

Yup - the Snells (same era) were also very good, but out of my price range at the time.
