Daedalus speakers are almost entirely made of renewable hardwoods except for the birch ply front and rear baffles, the front baffle being covered with solid walnut. I believe that the internal bracing is also solid hardwoods.
I personally believe that Daedalus speakers and the Ulysses in particular, are also the most realistic speakers I've ever heard, can be driven by just about any type and power rating of amp and to my eyes, are beautiful. Of course, everything after the "internal bracing is also solid harwoods", is just my humble opinion.
Whether this has anything to do with Lou's choice of solid hardwoods as the primary cabinet material is unknown to me, but I expect it does. I feel like the cabinets are also timeless in their beauty.
By the way, Lou is a great guy and I know of 3 high end audio manufacturers that use his speakers. One is a well known high power, solid state, power amp manufacturer, one is primarily a SET amplifier company and the third uses OTL's and makes really good turntables.
