Salon 2s are very hard to beat.
KEF Reference series have slightly better measurements due to the nature of the coaxial driver leads to uniform dispersion, the sound power/directivity is smoother than the Salon 2s because of the better vertical axis dispersion. But with coaxial drivers you generally trade off the smoother sound power for some mid-range dynamics because the midrange driver in a coaxial is designed for limited excursion (a moving waveguide is not a good thing...). The previous KEF series 207/2 along with Salon 2 were the co-winners the Stereophile products of the year in Class A. While Revel hasn’t refreshed their Ultima lineup since, KEF has come out with the new Reference series.
TAD Reference series are also great and would be an upgrade in a similar vein to the KEFs, although they are much pricier.
