The Revels you had already outperform the suggested Harbeths by a good margin.
My advice: don’t drink that KoolAid, it’s way overrated.
Anyhow, I would call up Ty of Tyler Acoustics and inquire as to what he could possibly build you for around that budget. Otherwise, there is a pair of Linbrook Signature Monitors for sale on that other site for $1200. Those will wipe the floor with most any <$6K/pair speakers currently available. For that price you are essentially only paying for the parts that went into building them.
