I read what the other fellow offered as well and ironically I had the opposite effect. It was the OMD15 that makes me feel like I am in a club listening to the band live. I put on the song "Private Investigations" from Dire Straits and my jaw hit the floor. It may be the mix of that album or the spatial dispersion of the Mirage design, but it was a notch better to my ears and only my ears.
These are both worthy speakers in my opinion and should not be compared against each other as they are two different designs and classes (book/tower) of speaker.
First, it must be noted that I was comparing the NrTs with the previous generation OM series that were built in Canada. I have never heard any of the OMD series, it could well be that they are an improvement over the OM series.
There might well be some other major differences in our gear as well. I mostly listen to high resolution material (SACD, DVD-A, or Blu-ray) over HDMI from an OPPO 83SE to an Anthem D2, and then amplified by a pair of Anthem MCA amps which are about 200 watts per channel.
I do believe that average quality content does not show the Sierras in their best light, but they really shine when given quality content. I have some Chesky SACDs that I really didn't know how good they were until played through the Sierras.
In my room, playing through my equipment, it's no contest, the Sierras are significantly better than the OM series. Maybe it's just cause the Mirages are old, and tired like their owner LOL.
