Mahogany would be my choice as well among the local guys options.
With Salk, there is no question of his ability to turn out beautiful finish, but Dennis would let you know if his local guy can't compete.
I'm not sure I'm in agreement about the remorse. I have replaced/upgraded gear over the years, but I don't really think of that as remorse.
I would have remorse if I bought speakers at retail price and 2 weeks later saw them on sale for half the price.
Or if I bought a Bose System then listened to real audio gear that cost half as much.
In the case of the Philharmonitor, you are getting the detail of a ribbon tweeter with a good 6.5" mid-woof, and a top quality crossover (important since the crossover is at 2.5kHz, where our hearing is very sensitive) for $1000.
If I was asked what the next step for a better speaker was, I would look at the Sierra-2 bookshelf speaker ($1448/pair) or maybe the KEF ls50 ($1500/pr). However, I would expect the improvements to be subtle.

Note that the Sierra 1 is priced at $850.

My points are:
1) the Philharmonitors represent a sweet spot. I don't believe you could find anything for $1000 to compete with it. What you could find is towers where the improved bass might offset the better high end of the Philharmonitors, but you would still want a sub with any floorstander you can buy for under $1500.
2) The Philharmonitors are at a level well above what you are likely to experience in your normal day to day activities. So unless you are actually looking for better speakers to envy, you are not likely to find them (but then, there is this site

).
I would not view it as being remorseful if you win the lottery and go out and buy a pair of KEF Muons or Focal Utopias

All of that said, ask Dennis about the dispersion of the Philharmonitors. I know the ribbons in my Philharmonic3's have very good dispersion, but not too long ago, you had to be in-line with the ribbon to experience its detail. He will probably tell you something like don't go more than 30 degrees off-axis from them, and you need to be comfortable that is consistent with your habits.
