I started a journey last year when I decided to buy an AMT, or Air Motion Transformer headphone (again). After enjoying it so much, I toyed with the idea of buying other unique driver headphones. Maybe... starting a collection focused mainly on different driver technologies, and trying to obtain one of every kind..? It's not like there are tons of them, so it should be pretty doable, right?
Enter the RAAL CA-1a — my first ribbon driver headphone.
