Thanks, guys. I think it will be an interesting contrast. I certainly agree that the Daedalus are special, and I could (and may) certainly live with them the rest of my days.
On the other hand, I am intrigued by the Double Impacts and feel that it is worth the gamble to give them a shot. Speaker preference, like most things in audio, is enormously subjective, so who knows how this might come out? One thing for sure, if the DI speakers are not as musical and enjoyable as the Ulysses, I will not be keeping them. But I am willing to take the gamble and find out.
