I have atcsm40 want possible alternative


I have the atc sm40's. My only complaint is they seem to  have to be played really loud for them to sound great. They are being pushed with hegel h590.     blusesound vault running through a mytek brooklyn plus              Thanks for any input

Have you considered any of the Dynaudio speakers? I am using the Evoke 20 and they are fabulous driven by my Pass Lab int 60.
The Audiovector R3 is amazing.  Spot on your budget.  Ultra natural sounding and revealing even at lower SPLs.  That would be what I would look at.  Check out Andrew Quint's review in TAS from May I think.
