Magico VS Daedalus VS Marten VS Spendor

As you probably know, choosing speakers is the most important of all in putting together a satisfying system. It is also a highly personal one since we all hear differently and have unique preferences when it comes to great sound. You also have a listening room that has its own acoustic qualities which will have a big impact on what sound you actually end up with. Also, it is highly unlikely that anyone will respond to your post who has heard each of the speakers you list in a controlled environment. So, (sadly) little that is posted in response to your question will be of much help with your decision. Having said that, JMBATKH is correct regarding the synergy between Dan and Lou's gear and I can personally attest to this since I am a Modwright/Daedalus client. Since the amplifier-speaker match is quite critical, if you are confident and happy with your Modwright electronics and in the absence of a demonstration of each speaker this might give the nod to Daedalus. But as Bhobba suggests, demo you must if you are really determined to find long lasting peace. I don't know about the other brands but Lou does have a trail purchase option that would allow you to hear his speakers in your room on your equipment. This is IMHO the best way to make a truly informed choice. If you do go Daedalus, I would suggest the Athena's given your room size. The larger Argo will likely over power a space that small and will limit your ability to position the speakers away from the room boundaries. Though I have not heard them I am quite familiar with Lou's "house sound" having owned the DA-1.1's for several years and heard the Ulysses at a friends house many times. As such my experience does not correspond with Salectric's, as I find the Daedalus sound to be slightly to the warm side of the spectrum overall and pretty darn full through the midbass. Salectric may be influenced by the sound of his SP-100's, which I owned some time ago and which to my ear have a slight boost in the midbass characteristic of the BBC "house sound". This is not a knock on the Spendors (the S-100's are one of finest speakers I've owned) or Salectric. However, compared to the Spendors the Daedalus (particularly the Athena) will likely read slightly lean when compared to the full midbass bloom offered by a BBC style speaker. Again, when all is said and done you really do need to do some listening (preferably in your own room) to make the right choice for you.
