Concerning the difference between the Omen and Superfly, I can’t do a direct comparison; however, the speaker placement is identical and I did not change the electronics and cables. The SF sounds a little more engaging, three dimensional and slightly more detailed. The most striking difference it the integration between the 2 drivers. With the Omens, I was able to tell that there are two distinct drivers, with the SFs I can’t tell. Just sounds more cohesive. I do not think that it is due to the reverse placement of the two drivers. Right now I have about 200 hours on the SFs, still not broken in completely. Do not get me wrong, the Omens are fantastic and a great value. I would have been quite happy with the Omens.
The speakers are on the second floor, I definitely will try a board underneath them. Thanks for the suggestion.
