How close to the real thing?

"Yes, but it's not exclusive. I frequently play solo piano CDs, and several times people have come to the door and thought it was a real piano playing."

I'm not obtuse, I hear what you guys are saying, and I can only conclude that I need to get out more. Neither my system nor any system that I've ever heard has been that convincing to me. I've gotten emotional, achieved satisfactory suspension of disbelief, and been in awe of the technology that made it possible. But I've never heard a system that I found indistinguishable from the truth. Those of you who have are my heroes.

Well, Phaelon, sounding "real" does happen for me, but not all that often, and, at least for me, only on solo recordings, and it takes just the right recording.

BTW, IMO people that buy audio equipment aren't heroes, people that engineer them are.

I think polar frequency response may have something to do with sounding "live". I've heard the Soundlab A1 sound live on a violin, the Soundlabs are of course dipoles, and occasionally my Revel Salon 2 sounds live (though not on violin, so far). The odd thing I've noticed, accidentally, about the Salon 2, is that even when you're sitting near one speaker you still perceive the stereo image *between the speakers*. This means that the Revel has some very interesting polar response characteristics, which might explain why they occasionally sound live, and my old Legacy Focus never sounded live to me. The Legacys had one of the most discernible "sweet spots" I've ever experienced. Great polar response might also explain why cymbals sound so realistic with the Revels, while their frequency response is certainly no better than other speakers I've heard.

The Legacys could fool some people on piano recordings though. Not me, but over the 13 years I owned them several people thought solo piano sounded live from another room.

It just seems more than a coincidence that the speakers I've heard "OMG live" sound from (Soundlab, Martin Logan Monolith, Linkwitz Orion, Revel Salon 2) all have different polar response characteristics than typical audiophile speakers.

Irv,
You can add MBL's to the 'live' category. Set up properly, a tough one, most shows don't allow for proper set ups for anyone, and a system as complex as the MBL's take time and space. BUT, when set up properly they're magic.

On the Sound Labs, I LOVE them--and you're 100 percent correct about their tonal/spatial characteristics...just right for my taste--an amazing product.
Irving M Fried, of IMF and Fried fame, used to show omnipolar frequency response of speakers--and did so more than 30 years ago. It was a.) ahead of its time b.) ambitious c.) evo/revolutionary thinking.
No body else (correct me here if I'm wrong {usually am}) does this any more. Why? Because the results are terrible.
Just as Jim Thiel showed Step Response Information, which displays the 'capture' of the drivers releasing the energy into the room as a unit body, either 'in phase' or not, with time function, lead lag information--strangely, almost NO ONE does this. Why, because their responses look really, really bad.
The now 21 year old design, the CS5's had a virtually perfect step response.
It would be interesting to see the Sound Lab Step Response,
because of it's design, it would almost have to be perfection too. Scientific (not evidence, because the ear is the final arbiter there) validation that what we're hearing is as it should be.

Great post.

Well said Irvrobinson, but that only serves to prove my point. True heroes are self-effacing. Bravo!

When I was in a band (quite awhile back), I had the use of a studio reel to reel (can't remember which make) that I loaned to record my own piano in my house. The replay through my speakers (Impulse H1 horns) was close to the real thing on playback ( through the said speakers).
So 5% is way of (IMHO) to my own personal experience.
I would say IMO that we are up to 90%+, and if ones hi-fi can differentiate between different makes of Instruments, ie a Strat from a Gibson, a Steinway (the baby)from a Bosendorfer (the daddy) then that % maybe even higher.
Again, 5%? one may need to upgrade ones gear.
