Well, I've been lurking around this forum for a while. This forum is very informative and good, however, I do notice that there are a large amount of people here who believe that the Khorn is the best speaker ever and do not even care to listen to the opinions of those few who dare post against the great Khorn. The Khorn is a great speaker, and a great value. However it is by no means the best speaker. I've had Khorns since the 1970s and I thought they were the best speaker period. However, a few years ago, I made a trip down to one of the new local "hi fi" stores in town and on display there were the Avantgarde Duos for $20,000. Mind you, I thought the Klipschorns were the best speakers period, regardless of price. I wanted to listen to them just so I could assure myself that my Khorns blew them out of the water. Well, this audition definitely did not assure me. It scared me. During the entire audition, I was sweating. I was realizing the fact that the Duos were resolving things my Khorns could not. The imaging was so wonderful and the soundstage was breathtaking. The bass was so real -- yet authorative. On my way back home, I could not stop thinking about that night. I went through all the possibilities, it had to be the room... maybe I was just mistaken. Maybe they just sounded "different" to me, that's why they seem like they sound better. Well anyway, I called them and asked them if I could bring my speakers and amp to compare. That same day, I brought all my audio equipment to the store. We took the Khorns into the room, placed them into the corners. Set them up and soon enough they were ready to go. I put in the cd I knew best and hit play. Wow. My Klipschorns were singing. They sounded so beautiful. I knew for sure that the Avantgardes were no match. After the fifteen minute song was over, we switched over to the Avantgardes -- using my same equipment. I was expecting them to sound dull. That was not the case. The Avantgardes made my Klipschorns sound like a TV speaker. I was shattered, I really was. I couldn't believe it. I switched back to the Khorn and it just sounded muddy, colored and, well, there was just no comparison. Surely there was something wrong with the Khorns, I checked all the wiring, made sure everything was in phase. Everything was perfect. I couldn't understand what the problem was. The employee at the store knew what I was going through. He told me that he too had Klipschorns and believed they were the greatest thing, but he moved on to Avantgarde horns as well. Anyway, I purchased the Duos and took a pair home. Set them up in the same rooms as my Khorns and well, they sounded even better in my house. And that was before they were broken in. The clarity was astounding. The imaging was wonderful. Everything was wonderful. I noticed no smearing in the vocals, nada. The advanced subwoofers of the Duos blended in seamlessly with the horns. But still I was not happy. I couldn't accept the fact that there was a speaker better than the Klipschorn. I grew up thinking the Klipschorn was the greatest speaker ever. I mean, even my dad would tell me this when I was young. This belief turned out to be wrong, well, at least now. I have to give the Klipschorn credit though, it is a 60 year old design that holds it's against the most modern technology. Yes, the Duo is a better speaker, but it doesn't quite sound $12,000 better. Considering the age and price, the Klipschorn is still an amazing speaker.
