Speaker recommendations, budget $10-15K


I am looking to upgrade my speakers. In particular, I am looking for better low-end extension than my current speakers, Sehring 703s, which the specs say go to 38Hz but seem to roll off above that. I primarily listen to rock. I have to say, I prefer a bit of warmth over ultimate transparency.

Ancillary equipment is a Pass Labs X150.5 power amp, Mystere ca21 preamp, Perfect Wave Mk2 DAC & Transport. Room size is 13x25. Speakers are facing out from the long wall. The speakers will be in my living room, so they cannot be too enormous or push the envelope aesthetically. I would prefer to buy new. While open to buying used, I am wary of shipping damage.

The speakers I plan to audition are:
Marten Django
DALI Epicon 8
Acoustic Zen Crescendo
Aerial 7T
Tannoy Kensington

I have also read good things about Vapor Audio Joule Black, but would have a real hard time auditioning them before hand.

I would appreciate any other recommendations of speakers to audition, as well as any thoughts about the speakers on my current list. Thanks.

Used Revel Salon Ultima 2, best speakers I have heard at any price (never heard Magico and some others). I can't say anything bad about them, find a demo. Great bass, I mean really great and everything else is good too. They are 22k new and around 12 used.

Wilson Sophia 3 should also be on a rockers list. Not as transparent as the revel but they are hifi with a little fun "beauty" as wilson calls it tuned in.
If you like the speakers you have now have you tried running a good sub with them for that lower end your missing?? I started adding subs to both of my listening systems and fell in love with my maggies all over again. Just a thought
Check out the new Nola KO's. I believe they're listing around 10K

One you've listened to guitar solos and lead vocals on open baffles it's tough to listen to conventional boxes again. You can see them in action on YouTube -just search for Nola ko.

Disclaimer: I've owned Alon's and Nola's in the past, and they're great - with great customer service. Currently enjoying Quad 989's. I'd recommend the quads because they're just so good, but its true you can't blast them. For me they're fine. For you possibly not. Good luck.
