Buying Used Speakers
I’ve bought and sold used stereo gear, cameras, and telescopes online for years without any issues. If you deal with the classifieds from a user forum, or sites such as Agon or usaudiomart, and from long standing members with good feedback then I ... 
Mint Protractor. A Pretty Nice Alignment Tool
I bought one about 10 years ago and never did like it, too difficult for my eyes. The problem with the Mint is that it’s pretty much turntable specific, change tables or tonearms and you likely need a new protractor. None of this matters as the co... 
How best to arrange cables in this room...
You say wood floor, but wood floor on concrete slab or raised foundation with a crawl space? If the latter, just run your cable through the crawl space.  
I have the W4S DAC 2DSDse and I have absolutely no regrets or issues with it, a very analog sounding DAC. The nice thing about W4S is that you can buy one of the lesser versions of the DAC and 5h3n send it in to be upgraded as budget allows.

Will a wireless streamer add problems to a signal coming out of a computers USB output?

H E L P !! Network issues with Teac NT 505?
I suggest upgrading your WiFi to some type of mesh system that will allow you to have a node located near the Teac, this will allow you to then connect the 505 via Ethernet.  
Powered speakers for a turntable
I’d still consider a small form factor amp and passive speakers. This combo is going to give you WAY more options for speakers. Powered speakers are going to have their own set of issues to deal with. Your going to need a power source for each spe... 
Why are there so few BNC cables to choose from
I would think a lot of it has to do with the fact that BNC connections haven’t been widely adopted by the manufacturers, therefore not a huge market for cables.
