This Should Be Interesting - Help Me Spend Money - New (Used) Tower Speakers...

The mission is simple, I enjoy all my Polks, but as with my amps and preamps, where I have grown to try new and higher end stuff, I want to now try some towers that might eventually eclipse my Lsim705's. At least one or two of my SDA's will never leave, because, as the saying goes, "nothing beats SDA".

OK - so here's the parameters, looking for suggestions for USED tower only (have to narrow it somewhere) speakers that after thorough and diligent and very patient searching, I could acquire for say... under $1500 a pair, hard stop, no $2K pairs please. I know that's not a ton, but it is a fairly wide range - and here are some thoughts below to get everyone started as well as associated gear, room, and listening info.

Please feel free to also ignore this long and involved post, but I tried to anticipate questions in advance.

GoldenEar Triton - (which models?)
Salk - (reaching - again – what to look for?)
B&W - (most confusing speaker lines ever)
Usher - (which ones?)
Focal - Aria, Profile or Chorus
Legacy Audio - Classic
Dynaudio - (which ones?)
Sonus Faber - Venere
Revel - Concerta
Dali - Ikon or Zensor?
what brands/models have I missed?

Associated gear and room –

Mantown – 8’ ceilings, drywall on all walls and carpet on floor. Large soft furniture for dampening, including one large stuffed ersine in the middle of the room, right behind listening position. I’d call it a fairly neutral room. Speaker position between 7’ and 9’ apart, and between 6” and 12” off the rear wall. 3’ to 4’ to the side walls and about 10’-12’ to the listeners ear.

Needs to work fairly equally well with:
Amps – McCormack DNA-1 OR Pass Labs x150.2
Preamps – EE Minimax “Tutay” modded OR Audible Illusions Modulus 1
Phono – Parks Audio Budgie OR Vincent Pho-800
Turntables – Music Hall mmf 5.1 OR Yamaha YP-D6 DD
CDP – Marantz 8400 SACD OR Sony S-9000es SACD

Listening style – almost 100% 2 channel audio, via a fairly even mix of CD, SACD, and Vinyl with the occasional BT Streaming through and Audioengine B1. Listening preferences vary all over the board, mostly all forms of classic rock, but jazz, classical, blues, reggae, female vocals, even some rap & country can be part of the mix.

I have really always liked the Polk sound, as you will obviously see below from my speaker selections, but generally I tend to favor what I would call a fairly accurate speaker, airy highs with detail, punchy mid-bass, and a present, but not overwhelming bottom.
I have already auditioned several models of vintage Infinity, Wharfedale Emeralds, Polk SDA 2a, 2bTL (modded), 1c (modded), CRS+4.1TL (modded), 5b’s, Lsim 705, several models of vintage AR, Klipsch KG-2, and Bose 901 Series IV.

Let the games begin - I appreciate any thoughts and suggestions!
