Thinking about buying new speakers....the Elac Uni Fi5 towers or the Klipsch hersery lll

I used to have a pair of Heresy III.  I didn't like them at all.  At low volumes they were so-so but when they got loud all the bass went away and they sounded very bright.  I run solid state for power.  They may sound better with tube gear, I don't know.  I got rid of the Heresys as fast as I could!

The Heresy IIIs are good speakers at the $2K price point when referring to speakers bought through the traditional dealer model. Nothing I own beats them for late-night, low-level listening. However, it kinda pains me to admit the $2K Spatial Audio M4 Turbo S’ are a much better value overall. They seem just as sensitive and beat the Heresys in nearly every SQ metric. The Heresys still have the upper hand when it comes to very low-volume dynamics, but I suspect that will likely change as the Spatials break-in.

I say this not to denegrate the Heresy, only to bring awareness to the incredible performance value I’ve discovered in the Spatials. The one caveat is they need a minimum wall distance of about 2' in order to produce ample bass, whereas the Heresys can be placed only inches from a wall.

Unfortunately, the elephant in the room...is the room itself. The room and setup will yield half of what you hear. Unless the room is acoustically as neutral as possible no speaker can sound it's best. Based on various poster's descriptions of their room I would venture a guess that the room and setup is the culprit for unpleasant sound, not the gear itself.
