No US "BMW grade" builders?
Also: disagree.
Mesa, Thunderfunk, Demeter, Jule. Fender SuperBassman300!
Seen the inside of an Ampeg Heritage SVT? Verellan Meatsmoke?
The Baer Vaklyrie will be an "artisan" grade amp, when it hits.
There are plenty more, that's just what popped to mind.
I fully agree on Demeter. You're probably right on Jule and Baer - wish the Jules were SS though. ...but that's just me.
