Defunct brands-


Do you or have you owned gear that, while you owned the piece- the company went under? 
I definitely have- most recently, Auralic. In the past- California Audio Lab. Both made good digital gear

Infinity as a high end speaker manufacturer.  In the mid-1990s they went mass market.  I owned one pair of their bookshelf speakers and then a pair of RS-IIb floorstanding models.  Awesome sound.

I don’t think the current KLH has any relationship to the old company except for using the name,
