I've heard both. I favor the 7-ES2. Even though they are older, I feel the sound is more accurate, with zero listening fatigue and midrange to die for. The 7-ES3 is great too, but perhaps is adding some coloration in the lower frequencies. Both generations are examples of how fine, monitor-style loudspeakers should be engineered. If you have superior recordings in your collection of music, you will want to listen all day long.
Harbeth 7es2 vs Harbeth 7es3
I'm curious to what difference these speakers have. I researched a Harbeth 7es2 for sale. The seller claimed the woofer was replaced with the woofer from the Harbeth 7es3 by a dealer and the dealer claims the woofer speakers are identical with both models. Any input would be appreciated.
