Best skiinny floorstanders

I think Audiovector R 3 Arreté is worth a look, especially coming from an electrostatic. Extremely fast and clean while being balanced and musical. I would call it neither warm nor lean, but rather quite neutral, which will make it somewhat sensitive to amplification matching - you will really hear which way the amp leans. Plays much bigger than its diminutive size as well, but is easy to integrate (works well close to the back wall). The review in TAS is quite complimentary and it was made an Editor’s Choice, but I think their evaluation only scratches at the surface of the speaker’s capability. (I am admittedly a bit of an Audiovector evangelist given I have made them my reference speakers but have no business interests whatsoever, I bought them from a retailer like everyone else.)

wonderful dispersion

Sorry, missed the comment about room size. The R 3 is super capable and dynamic but it might be a stretch with that much volume. R 6 would be up to the task, but that’s 3x the money. But FWIW I’m considering the R 3 for a 13x26” open space with 12’ ceilings, so volume is similar to yours.

Love the Acoustic Energy AE520 all carbon drivers, slim nice cabinets sound great especially with tubes and will save you money. Using Mastersound Box with blusound node2. Just my 2 cents.
