Like everything else, what you listen to, how you listen and what virtues are important in the reproduction of music are paramount in making a decision as to whether the Merlins are the right choice for long term enjoyment.
I've owned them for 2 years now. I echo everything Phild says. They are not headbangers but refined, fast, revealing and naturally balanced speakers. They are very room friendly but prefer small to medium sized rooms. If going in a large room, a sub should be considered. After attending the NYC audio show in May, I didn't hear a system that would encourage me to supplant them. Part of the reason is that it has taken me a while to get the refinement and enjoyment they give through systematic trial and error. The only component still around since I've owned the speakers is my trusty JVC 1050 Zn used as a CD transport.
They really are as good as the press says but like everything else in this hobby, won't make everyone happy. What does make an audiophile happy? A new toy for a short time and then what, another new toy? Whoa nelly, time to settle in and listen to some music. What is the point of components if not to serve the music? The Merlins do serve the music very well and I dig them for just that reason.
Virtually everyone that has listened to them in my home, casual listener to audiophile has commented on the "clarity" and "sounds real" aspect of the system. No, they dont do micro dynamics quite as well as the best stats but certainly as well as any dynamic speaker Ive listened to only to improve with what is upstream. If you consider them you may have to re-evaluate the rest of your system. While they work well with a wide variety of components, to realize their true capability will require patience and commitment. Im not sure that Ive found the limits of this design and that is one reason they are so amazing.
The mids are full, rich and there. The highs are as extended and clear as the recording and upstream components will permit. Soundstaging and imaging, which is not at the top of my priorities is, again as good as the recording and upstream components. On some recordings the speakers and walls will disappear. Off axis listening is a joy. The stage doesn't collapse away from the sweet spot as do many speakers. These speakers sound great in the next room. The bass is taunt, fast and natural if not having the bass energy of larger systems. The BAM in battery mode is enough for me most of the time except for those headbanger moments that are becoming more infrequent as I mature :^)
PS Stay tuned, the long awaited subwoofer to match with the VSM is just around the corner. I understand that Bobby is currently designing it.
