What does one purchase after owning horns?

Mapman, I completely agree with your assessments, although, I still do not think those "non dynamic" live performances are easily duplicated by a system. But it can be close. Whenever I listen, tweak and/or evaluate a system, I bring along two Sheffield Labs recordings. The Drum and Track record, and Prime Cuts. I have used these for years. They show me immediately all strengths and weaknesses in a system. I use these as a reference because of my familiarity with them and, my liking of them. Once I approach my preferred listening levels, it is quite amazing what findings become apparent.

Since the discussion revolves around dynamics.

I'll just mention that the Sheffield Labs Drum Track XRCD is a good way to compare speakers for dynamics. Horns or no horns it takes considerable engineering/technology to play these drum tracks cleanly (no audible distortion) with brief but sustained levels over 110 db SPL at the listener, as measured with a Radio Shack meter on C weighted.

Shadorne Absolutely !

A musician friend of mine came over to my place the other week, he had previous not heard my horns, I played some cd's, and his comment was how 'clear' they sounded and he cheekily asked If he could he plug axe into them!
Does 'clear' mean, open, forward, colored, bright?
or all of the above?I care not as they float my boat, or should that be ship? lol.

"I still do not think those "non dynamic" live performances are easily duplicated by a system. But it can be close."

Yes, I agree of course that nothing can be duplicated exactly, especially when translated from a large venue into one's listening room.

But My point is that I do not expect exact replication, only quality reproduction within my own space, and I have no issues being satisfied fully with the dynamics aspect of the reproduction in my case, sans horns.

Nevertheless, I would very much like to try a pair of good horns in my home at some point in that I am always interested to hear what other kinds of good reproduction may sound like. Each usually has its own set of things to like.

Just like two talented artists, like Monet and Rembrandt, would offer two radically different but each uniquely interesting renditions of the same subject matter if given the opportunity I would expect.
