Best Speakers with a DNA-1?

Cheeg, go see Randy at Optical Enchantment.  He's over near the 3rd Street Promenade I believe:  http://www.optimalenchantment.com
He has a lot of great gear and has been doing this for years and years.  I'm sure he'd love to help you.  I don't know him, but friends who have purchased from him over the years love him.  They say he is not high pressure at all and loves to teach.  

Let us know how that goes. I don't know his full product line as I just did a search in your area.  I just got back from Pasadena for the Rose Bowl.  I used to spend a week or two a month in the 90's for business.  There was a great high end store off Colorado that had Avalon's.  Closed now, but in the day they were awesome.  

Oh, used Treo's are going for about 4,800-5,700 or so and they are rarely on the market. Right now there haven't been any on the market since October 2017.

+1 ctsooner, 
I bought yours.
I'd say that the prices you quote would be for the CT model, and those are as rare as hen's teeth.

If earlier comments are true, the old 2Cs are ‘magical’ — how much more magical can they get?

As has been said before, Mr. V. just keeps adding newer bits and pieces to his speakers, so the closer you come to current production, the closer you are to buying new. The differences are slight, but noticeable.

Actually there are none for sale right now.  The prices are for the regular and not the CT.  The only CT I saw that has sold went for around 6k

@ctsooner — I was referring to the Treo, not the Treo CT. Used Treos have selling for ~$3000, which is about what a new pair of Vandy 2Cs would cost. I can also get used 3Sigs for much less than a new pair of 2Cs; wouldn’t both of these options make more sense?
