[please excuse my poor English]
Just a few thoughts:
- buying a $2700 speaker blindly is like having your cat ordered on Amazon, and have it delivered by drone: completely, totally, dramatically nonsensical. But I am European (nobody’s perfect)...
- Harbeth speakers sound better
- on acoustic instruments (classical music, vocals, folk). They are not for rock, IMHO.
- listened near- or mid-field. Do not try to put them in a big room, sitting 5m away, pumping up the volume, in hope they will deliver the thrills of a live rock concert. They won’t. Instead, they will play like a "big radio gear".
- Sitting not too far, you have to look into the sonic landscape they produce, instead of expecting that the scene "jumps to you" //hope this is understandable...
- at low to moderate volume. The can play louder, but it is not what they prefer.
In these conditions, they are terrific speakers if you favor timbres, emotion et delicacy (ex: unamplified acoustic music), at the expense of sheer energy and attack (ex: amplified rock concerts).
I upgraded from M30.1 to M30.2 Anniversary. I compared them at home. The M30.2 Ann gives me more detail, is more transparent, lifelike. Its low-mid is less exaggerated. And the M30.2 Ann remains a highly musical monitor.
