I know nothing of anything new coming from Roger, but up to at least very recentyly, he paid Coda for their technology and built his own goods using Coda boards and chassis. If you call Doug Dale at Coda, he will give you age and model comparisons based on the Coda board in the Sanders or Innersound products that you are looking at.
The current Coda stuff is very good indeed, it is worth the phone call as Coda sells manufacturer direct only in the US.

Apparently Sanders Sound evolved from a failed company called Innersound, of which Roger Sanders was a part. Another post in a different thread said that Roger bought boards and tech from Coda but makes everything himself in Conifer, Colorado. If that is true, and he sells 6 units a year, Sanders Sound would be the industrial titan of Conifer, a sleepy little mountain town about 40 minutes west of Denver.
