Corazon/Theo,
Points well taken.
Why change the color?..the room where I listen has a mix of chocolate-brown oriental furniture and a couple pieces of furniture that are dark wine-red in color. The Snells are the odd-man-out with an oiled-walnut color. This is driven purely by aesthetics. If the Snells were rosenut..it would look very nice.
No doubt I might be unhappy with failed results, that's why I'm looking into options. "Rosenut" is just walnut stained with a red mahogany or cherry stain(or more likely dye..fine furniture is often dyed due to greater transparency). So this isn't odd..just converting from one color to another is odd.
One veneer over another and sound quality..yeah..that's a big unknown & if I mess it up, going back won't be so easy. Top veneer glue raising the bottom veneer/glue..surely possible, but in my woodworking experience, unlikely. Any veneer adhesive these days is high solids(low solvent) and the first adhesive is cured to a brick by now. Telegraphing..possible if the base veneer were flat-sawn oak or ash(ugly wood..to me), but what's there is a very fine walnut surface. Add adhesive and more veneer and it would be fine. Resale..I know & I don't care. We're not talk significant money here. If they were worth 5-10K on the resale market, then I'd care. The sound appraoches 5-10K..which is why I'm keeping them. All the possible reveneer issues is why I leaned toward restain(dye)initially, that and cost. I'll admit, given everyone's thoughts, I'm reconsidering the entire project.
I would be interested in your(anyone's) thoughts on other speakers that have the Snell's sound signature. I'm aware of Vandys, but not of others, first hand at least.
