I own the Vandy 2ce Sig II's and have heard the Ohm 1000s.
In my opinion, the Vandy's are at times enthralling and other times lackluster. It all depends on the source material. If you throw a reference CD at them eg, Fleetwood Mac-Rumors, Steely Dan-Gaucho, etc. They can be absolutely sublime and thrilling. I've also found in my room, that they can get congested in the mid-range and lack detail in the top end.
If you listen to acoustic jazz like Ray Brown or Bill Evans they sound great. It seems the more sparse the music (like Muddy Waters) the more enjoyable they are to listen to. Once the music gets dense, like I said, they can get congested. I find that I just can't throw any old CD at them, sit down, and enjoy the music.
I demo'd the Ohm 1000s at their shop in Brooklyn, NY. It was in a warehouse setting, so the environment was not exactly optimized for critical listening. However, as other have mentioned, the sweet spot is literally everywhere. I was able to roll my chair around and not have to worry about being in a +/- 3" listening window.
The Ohms seemed to have more air on top in the treble. I was able to hear more detail. In general they were just very "fun" to listen to. I threw on the Police, Led Zeppelin, Rush and it all sounded "good." I found that the Ohms lacked the mid-bass punch or slam that the Vandy's have. And being a semi omni-directional speaker there was a vagueness with respect to imaging where I couldn't really identify where instruments were located in the soundstage.
I would love to hear the Micros or 1000s with a set of subs. Also, from what I was told by John and Evan? is that all of their speakers are designed to sound the same. They are just sized differently to suit the size of the environment they're placed in.
To me, the Ohms are the ultimate speaker for hosting guests or for entertaining. Everyone in the room would have access to clear wonderful sound. I may still get a pair of the Micros if they ever come up cheap just for that purpose.
Not to go off topic, but I just placed an order for the Tekton Electrons and expect them to be delivered within a week. I'm very excited to hear them.
Cheers,
Joe
