You will see Sierra Acoustics from time to time, as well as some Pioneer Andrew Jones/Elite stuff. Chane also occasionally makes an appearance. The Yamaha's used to make a regular appearance as did the JBLbefore and after collaboration. The headphone stuff just seem to sell better in this community. I'm also a stickler for buying gear like that from Authorized Sellers only. Many of the headphone users aren't that experienced and are fairly new to enthusiast level gear.
