I've built Danny's XLS Encores with upgraded crossovers and tube connectors.  I'm about the build a pair of CSS Audio Triton 1TD-X with superior crossovers for a separate area in our home.  I'd like to have the flexibility of both tube connectors and binding posts on the back of each speaker.  I'm not quite sure how to do this with good connectivity to each.  Jumper wire between the tube connectors and binding posts?  Separate wires from the crossover to each set of connectors?  Other?  Also, any suggestions on a good set of binding posts that are non-metallic.  The posts that come on the CSS Audio DIY kit have metallic nuts and washers while the post itself is non-metallic.  Will the metallic nuts and washers make an audible difference on these speakers.  Thank you!!!

I did exactly what you're talking about with my highly-modified CSS Criton 2TDx speakers. I used a Dayton Audio mounting plate that accommodated two pairs of binding posts and mounted one pair of binding posts and one pair of tube connectors.
I duplicated the crossover feed wiring, running one pair to the tube connectors and another to the binding posts.
In all honesty, I can't hear a difference between the two types of connections.

Outside of tube connectors, some of the best I've found are KLE. Pricey, but super easy to solder and have a very nice sound.

It's not whether the binding posts have "metallic nuts and washers", but whether or not these fasteners are magnetic. You want to fasteners and connector parts that are non-magnetic.

If you need to use binding posts, as I have to do*, I'd recommend using WBT binding posts. (*-my speaker cables are Shunyata Research Alpha v2s, and are too heavy to use with tube connectors).

WBT is very widely-regarded in the speaker manufacturing industry, and makes a wide range of excellent binding posts with excellent engineering specifications and various price points. Link to WBT: http://www.wbtusa.com/pages/0763m.html

Here's the WBT - 0705Cu



Description:
WBT's flagship terminal with compact design. Equipped with filigree signal conductor made from pure copper that is directly gold plated and constructed on the nextgen principle. Grants highest conductivity. Fully insulated. CE and IEC conformant. Accepts 4-mm bananas, spades as well as crimped cable ends up to 4 mm² (11 AWG). Outer metal cap with platinum finish.

Also, if you need speaker cables, I'd also recommend Danny's GR-Research speaker cables, as well. Excellent design topology and excellent quality materials used for the conductor and dielectric (insulation), as well. Here's the higher-spec 24 strand cables, but 16-strand are also available at a lower price: https://gr-research.com/product/24-strand-diy-audiophile-speaker-cable/

For speakers I will keep, I will use tube connectors; however, I have a pair that I need to probably add a pair of binding posts to the external crossover, to make it more appealing to a potential buyer who may use spades.  So, I've been thinking about this exact thing... "which low mass binding posts" (that also don't cost an annoying amount of money)? 

I really like the Cardas Binding posts I've handled on speakers before (Merlin Music VSM) and they're used in my Ayre amps.  They have a short version... Cardas copper --> Silver --> Rhodium plated. The posts are quite small and I've wondered about using my lathe to drill out the center of the post, so it can also accept a banana / tube connector and still accept a spade.  I suppose I'd end up with bare copper for the banana connector that I would need to keep protected / cleaned. That could be a single option that is great for all connectors.  Recently I found a pair on eBay for $60/pr.  Highly recommended.

Note the small size of the rhodium plated post. They could be drilled thru to make hollow:



HiFiCollective has a bunch of stuff as well.  I've also found these two as possible contestants down the road... the others mentioned above I'm sure are good as well.  I've also handled WBT on other speakers and they seem well made.  Some note things like they don't plate with nickel prior to rhodium, and the AECO specifically mentions being "low mass".  Which are the lowest mass of any of these, I'm not sure. 

To connect them, I'd use the tube connector as the primary mount and mount a pair of binding posts as well.  Inside the speaker, I'd solder the crossover to the tube connector, along with a jumper that goes from the tube connector solder point to the binding post solder point.  I.e., the binding post will have the tube connector "in the way" / between it and the crossover, rather than the binding posts being in the way of the tube connector and the crossover.  The tube connector will have the preferred path in the setup. I guess doing direct runs from the binding post to the same crossover solder point is fine as well.  Whichever is easiest.

I think these are only $15/pair!
