You may want to research the single driver speakers made from hemp. I own the omega maxhemps with triode corp. parallel SET monoblocs and can attest to their many strengths. I was told that the hemp driver is superior to fostex. I have never heard the fostex or Zu's so take my comment with a grain of salt.
I went from piega c-8ltd speakers and ss amplification to the single driver, SET amp setup and am very happy.
