Speaker suggestions please - going to the BIG city


I've received some excellent advice from this forum in the past and I'm hoping you can help with speaker suggestions.  I've had my Martin Logan Summit X speakers for five years.  In that time, I've updated all my components and cables, but not the speakers.  When I purchased them, I lived in a small town and it wasn't practical to travel to the big city to audition others; they were a strong suggestion from an audiophile friend.  I very much like them, but I have a hankering to upgrade, or at least consider other brands that will compliment my system (see below).  I don't want to change my Primaluna HP Integrated because I like it, and I recently upgraded all the tubes at a cost of $1300. 

I listen to jazz, female and male vocals, quartets, etc.; think Jewel, Melody Gardot, Nora Jones, Neil Diamond, Alison Krauss, etc.  Never hard Rock, and never overly loud. 

My room is about 18x25 with a vaulted ceiling and open behind the listening seat by another15 feet (the kitchen). 

I have an Axiom Audio sub in the system that I've also thought about replacing.  

I'm heading to Portland and Chicago in the next few weeks and have time to audition speakers.  I'd very much appreciate your thoughts on what would sound the best considering my music choices and Primaluna amp.  I know I could just listen to everything, but I'm hoping you can help me narrow the choices.

My system:
  • Martin Logan Summit X speakers
  • Holo Audio May DAC (Kitsune edition)
  • Lumin U1 music player
  • EtherRegen.
  • AfterDark clock and power supply for the clock and EtherRegen.
  • Roon Rock using a NUC that I built
  • Acoustic Zen Hologram II speaker cables
  • Acoustic Zen MC2 and Kimber Kable D60 digital cables
  • Acoustic Zen Matrix Reference II interconnects
  • OPPO 105D player for DVD and SACD disks (modified by Ric Schultz).
Thank you!
Steve

May I suggest the Dali Epicon 6 or 8. Here's a link:https://www.dali-speakers.com/us/products/epicon/epicon-8/
I live near Portland, and I think Echo Audio carries them. I have the earlier version of the 8's. Check out their tweeter/super tweeter assembly. Amazing for voices.My room is around the same size.
My advice would be to go to AXPONA at the end of October if you can make it. There is no better way to hear a wide range of speakers to help you narrow down the field.
If you like the soundstage that the Martin Logans throw, I would look at either Raidho (X & C line models can be had in that price range) as I have heard the driven by a PrimaLuna amps and they do very well. 

Audiovector is another option though the R3 is a bit below your budget and the R6 is way above but they are really good.  There is definitely a dealer in Chicago for them.  

MBLs would be the best speaker in this price range for that big immersive soundstage but you can't dream of driving them with the PrimaLuna amp.  
Martins are excellent speakers and I do like them a lot, but when I heard the Omen Defs Mk.2 next to them I was amazed. And it was not an efficiency thing as I had my dB meter calibrated to an NIST standard with me at the time. Compare as many speakers as you can! If you can find a dealer with Zu Audio products, at least take a test drive. I have 5 Jewel CD's from her 2004 "Instant Live" tour, they still bring chills. My favorite is the one from the Mountain Winery in Saratoga.
Atohm doesn't have a lot of dealers in the US, but one of them is in the Chicagoland area.  Worth seeking out.
