Mr_bill, do you mean have I heard them ? Have not owned them, but a friend of mine, on my recommendation, replaced his B&W 802, series 3s, with a pair of Palladium P38s, I found used. Went with him to pick them up. I really loved the sound over his 802s, ( no comparison, imo ) but he grew tired of them after a few months and sold them. I had the opportunity to purchase them prior to him, and could have purchased his pair, but have always preferred my LaScala. He made a profit on the sale, and gave me 1/2. His system was a Sunfire Theater Grand Four and Sunfire Cinema Grand 405 wpc amp. I heard the 37s on several occasions in 3 different systems ( one was in my system in a previous home ). I never heard the P39s. As I said, they are, without a question, a Klipsch, and excellent, but " I prefer " the mids, and the bass loaded horns on the Lascala…. viber, as far as overdamping, I went, and go, a bit crazy ( extreme ), because the horn should not have a sound of it’s own. I dampen the cabinets as well, and further isolate the crossovers: just some of the things. I agree with you on turntables and tonearms, as you are " creating the marriage " for the stylus / record. I like the AGs horns, as when I hear them at the proper listening distance, I do not notice an issue, but up too close, I do, and yes, they are not a point source when too close. I have heard the Vittora, twice, at shows, and do not hear the softening you speak of, but feel they are very " smooth ", if you feel that is the same thing. I personally do not feel they are the same. I have heard about horns being made out of many different materials, such as granite, marble, corian, and yes, concrete. As long as the concrete surface on the inside of the horn was polished smooth, I would imagine it can work. Until next time. Enjoy ! MrD.
