Not sure its is my favorite, but my VA PO's in the Big Leaf Quilted Maple are stunning! The fit and finish is on par with the very best I have seen.

Sonus Faber does some nice work too..

Sonus is an interesting case. . . rather than constructing speakers with plywood, they layer selected veneers in place with crossing grains into a custom ply pre-molded to the shape of the speaker. I understand that the top models use over 20 layers of veneer.
Higher end Sonus speakers are more/less all curves. .. hence the heavy use of custom plies. According to Sumiko, by using these custom plies Sonus achieves higher rigidity/damping with low mass. G.
