Factors
Ownership
100.0 reportedCA 100%
The vendor's own contact page names Al Freundorfer as the person currently operating the business, having taken it over from founder Lloyd Peppard. A Corporations Canada federal registry search for the name returned only the blank search form rather than a processable result, consistent with a one-person business that may not be federally incorporated, so this stays reported rather than verified.

The site does not say where its vacuum tubes, transformers, or wood chassis stock come from. Vacuum tube audio gear generally depends on tubes made outside North America (Russia, China, Slovakia and similar sources), so the mix assumes tubes and most electronic parts are imported, with a smaller domestically sourced share for the standard maple and oak chassis stock; this split is an estimate, not a published figure.
- Welcome to Mapletree Audio Design vendor_statement “In addition to the standard maple and oak, exotic hardwood end panels are available at extra cost. Shown below (L to R) are Ebiara (Red Zebrawood), Yellowheart, Walnut, African Sapele, and Roasted Ash.”
