Here is the Brutus award winner for Dave Clark of Positive Feedback:
Vandersteen Quatro Wood CT loudspeakers (Read the review HERE)
Nothing to add that hasn't been said in my review and elsewhere by other reviewers... simply amazingly musically killer. We bought the review sample.
Here is the whole review: http://positive-feedback.com/audio-discourse/vandersteen-audio-quatro-wood-ct-loudspeakers/
He and his wife bought the review pair. As for even the Treo's, like I said the bass goes down into the 30's before giving up steam. It's not a huge woofer and the laws of physics apply, but it gives satisfying bass all the way down. Never muffled or woolly. It's just not the Quatro with the built in subs and the 11 band eq. I personally haven't heard digital EQ done properly. That's one of the things I didn't love about the Persona 9H. They were like most Paradigms for ME, in that the highs were accentuated too much, but the bass wasn't fully coherent with that Anthem EQ. Again, that's just me. I found the Treo's were driven nicely at reasonable volume, in my room with a 60 watt Ayre AX7e I had before upgrading to the AX5/20. It's a zero feedback design which I prefer in amps and it's got plenty of current to drive speakers, but the Vandersteen's spec out nicely and are actually very easy to drive. I've heard Treo's driven by the 1800 Belles integrated NICELY as well as the mid level NAD integrated. The Belles crushes the NAD IMHO, but you can easily put together a satisfying system using these amps with them.
Again, they may or may not be YOUR cup of tea. I didn't even like them when I first started my search for speakers to replace my 20 year old Proac's a few years ago.
As for horns, they are the most exciting speaker type on the market. You can run them with flea watt amps and they are a blast. I finally got to hear a set a few months ago. I understand why folks love them, but they just don't do justice with vocals. Their mids are not as good as a panel or a great dynamic can do. Even folks who sell them and love them will tell you that if they are truthful. They are an easy sell if someone just wants a fun, dynamic speaker to listen to big music with. There is a great market for that and it's why they have been selling so well for years and years and years. Heck, my first 'true love' speakers were the Klipshhorns in 69. I wanted any of them. I couldn't afford them at the time, but i got my buddy Frank to get a pair of the Heresy's with our Yamaha CR 620 (a top vintage receiver) that my former brother in law still runs daily and loves with newer speakers. Franks system was fun to listen to rock with, that's for sure.
Again, JMHO's on all of this. I have changed how I listen over the years as I learn more. I just listen differently than in the past.
