Why do we all know real when we hear it? In answer Valin says we it takes both superior parts grouped together in a way to provide a neutral and complete presentation. That's actually a non-sequitar, but I suspect most don't care; Valin's words sound nice - who could disagree with them? Is that what real or 'natural' mean - neutral and complete?
Tim, I enjoy reading your posts and your efforts to analyze what others have written. Your last sentence here is interesting.
"Is that what real or 'natural' mean - neutral and complete?"
I think the problem with neutral and complete is that it is so difficult to know for sure if something (a component, a system, a recording, a concert hall, an instrument, etc.) is ever truly neutral and complete. Do we measure this somehow? Is it understood to be so only in direct comparison to something else, that is, is it relative?
Valin and ddk both describe the differences we hear from sitting in different locations and in different halls. The instruments themselves are different too. In my view, there are many different flavors for how a real violin sounds: what violin, who plays it and in what hall? What about the bow? Even, who hears it? I think there is no way to know truly if something sounds neutral or complete. There is only more or less neutral and more or less complete. But most of us know clearly and instinctively if something sounds real or natural.
I began to understand this more clearly when I was in Utah visiting David Karmeli. We listened to different turntables, cartridges, and speakers, two different rooms and slightly different Lamm components. To me, it all sounded natural, perhaps not quite real, but more real than all systems I had heard before. And this held for each combination of gear, speaker, turntable, cartridge, and room. The big Bionor system with the AS2000 and Neumann cartridge were my favorite, but there was also some magic to the Thoren's Reference and Ortofon A95 SPU. At this level of naturalness, I was not really thinking better or worse, but only different. One was not more real or natural sounding. However, one was slightly more neutral and complete relative to the other.
I learned that there are slight differences for sure, different flavors, and different presentations, but the underlying quality that made them all sound natural to me remained clearly audible. I outlined those qualities in one of the opening posts in the thread I started describing that visit. I described the differences as similar to hearing to the same conductor leading the same orchestra playing the same music in three different halls: Chicago, Boston, and Vienna. As I think of it now, it could be different conductors leading different orchestras playing different instruments playing the same music. We would still know the music is live and real sounding, it is just presented slightly differently and with a slightly different flavor or accent.
It sounded very close to real and incredibly natural, but there was no way to know if it was neutral and complete. It was just more neutral and more complete than what I had heard before. David is designing a new turntable which will likely be more neutral and more complete sounding. The real and the natural cover a range of believability, yet we are all surely convinced that an actual violin sounds real. Perhaps Harry Pearson did not lose sight of this range of believability, but it seems his writings and thinkings and system set up reflected a very specific sound based on his singular perspective from his singular seat in Carnegie Hall. It was surely real, but it seems now somewhat limiting.
