End Game(ish) Speakers - Help Deciding

I just did a lot of demo’ing in the same price range. O Audio and Devore were my favorites. Sounds like Volti could be a good choice for you. 

@chris71 I don't usually get the opportunity to comment on Speakers as I have not heard many of the models that usually show up.

I do know Models from Companies referred to by yourself and can be sure there are quite different End Sounds being produced between the Models. 

 Altec Lansing - Klipschorn  - B&W 801/802 D3 or D4

I am also quite familiar with work undertaken by Joseph Crowe and have communicated with him in the past.

The Links below will put you in front of a Type of Speaker Design you have expressed an interest in, as well as numerous others.

Note: That Drivers and Xovers selected by both Crowe and Graveson in the case of certain models are to be found in Commercial - Branded Models costing easily near £100K. Using these designs as a DIY route to produce a Speaker will reduce an outlay to almost parts costs only.

Think Board Material and Cutting at £1K maximum depending on Board Materia.

Think a Cabinet Maker assembling at £500 + £300 for adding a Veneer selection if if this is wanted on the Cabinet.

Drivers + Xovers are between £1500 - £5K depending on the Speaker Design and quality of Xover parts selected.

My own experience of this for a design selected is a total outlay of approx' 50% of the maximum total shown above.

The B&W D4 when I experienced a demo left me stating it is a Speaker that is a very close mimic to a ESL Speaker when being driven by a SS Amplification. I was really hoping it could have also been heard on another occasion with a Valve Power Amp' but the Speakers are not logistic friendly to be moved to alternate listening spaces.

I have also recently heard the Klipsch Jubilee and was enthralled by the overall experience, but they are the antithesis of the ESL Speaker types I have lived with for such a long time.

I will state, from after COVID and return to normality, my most recent experiences of visitations and being introduced to alternate speaker designs has led me to have a complete rethink about ESL Speakers and I am enjoying Cabinet designs with a new gusto. 

Currently I have superseded older owned Cabinet designs and replaced their regular usage with new types of a design for a Cabinet Speaker, it looks like this is to be taken further and another Cabinet design will supersede the owned ESL design.   

After spending years swapping out speakers I found my end game speakers a few years ago when I got the Vandersteen Quatro CT. They have a newer version now that would work with your integrated amp.  It's the Quatro CT EVO. It is about $23000 US but still less expensive than the Sasha. The built in powered subs can be adjusted precisely to your listening room to give you optimum bass.

I have the entry-level Volti's (The Razz), and I think they are wonderful. When I think of large, shared spaces, Volti has the kinds of finishes that can make them a feature, rather than a wart on the decor. The owner Greg will work with you on his beautiful veneers, and I bet you and your spouse would be happy. I think most reasonable listeners would be more than happy with the sound, if you already have a predilection for horns. A Volti Rival in a choice finish might be an end game choice. The Vittora is a bigger financial investment, but look like they could be sonic furniture that deserves to be handed down.

curveball, but if you like the efficiency and dynamics of horns but want a great midrange, consider Tekton.   

I’ve owned B&W supplemented with folded horn subs.  I’ve owned maggies and Martin Logans - and my Ulfberht’s give me the slam and imaging I missed with my traditional setup, while providing the amazing midrange and sound-stage of my planar/dipoles.

I started with smaller units - ’paid’ for them to demo in my home and loved the midrange, but like you wanted something full range, so called them back spoke to Eric, the owner, told him what I wanted, he suggested the Ulf’s and provided full credit for the upgrade, and we ’swapped’.    I’m very happy.  I go to high end stores locally (where I bought my T+A pre/pro-  they have amazing brands) and I can’t find anything for under $50k that sounds better to my ears.

The only thing I’d change is more cabinet bracing - doesn’t become noticeable until you really push them to concert levels (I have Purifi Elegant monoblocks from Buckeye so a lot of power for such an efficient speaker)  I may try some of my own dampening on the inside/sides of the cabs by removing the woofer - TBD.

They’re not a traditional brand, but you can hear them in your own home and decide for yourself, removing a barrier you list in your post.

The ’ready to ship’ page has even better pricing, but stock changes: https://tektondesign.com/product/specials/1-pr-moab-w-upgrades-black-finish-5200-delivered/   << demo the Moab’s, if you like them and want/can afford even more, just upgrade during the return window.
