To properly appreciate what this whole technology can do, you have to complete several boxes on a checklist:
(1) have a terrific headphone/amp system, because the better this part is the better will any reproduction be as heard through your ears. I cannot vouch for anything but Stax electrostatic "open" systems, as I've only had Stax ever since I got into the world of headphones back in 1995. Never tried the Realiser with "closed" or dynamic headphones, and quite frankly I have no interest in doing so. I'm a Stax believer, especially with the Realiser.
So my "system #1"
vintage 1995 is an Omega-1 paired with an SRM-T1S tube amp. I still use it today, along with my "serial #0001"
Smyth analog A8 Realiser (no HDMI input, but 7.1 analog channel input as the only source). My "system #2"
is vintage 2013, and is an SR-009 paired with an SRM-007tii tube amp. I use this setup with a second HDMI-enabled A8, and it is astounding.
As measured to digitally describe how your ears and brain hear sound through this headphone/amp equipment, this will be your HPEQ for all of your Realiser presets whenever you listen to anything through this equipment, to go along with any PRIR's you collect. The combination effect is to "perfectly duplicate" the sound of that room when you play any new real source material, as if you were listening to that real source material in the exact physical listening environment in which the PRIR was created.
(2) find a terrific sounding multi-speaker room fantastic listening environment or studio that you lust after to have in your own home, if only you had zillions of dollars and could build one without a problem. Then arrange (if you can) to come over or rent an hour in order to perform a PRIR measurement in order to capture the exact way that listening enviroment sounds to your own ears and brain. Every nuance will be captured by the calibrated microphones placed in your ears via the test sweep frequency tones sent by the Realiser individually to each speaker in the environment. The audible effect of floors, walls, ceiling, baffles, electronics, speakers, speaker placement around, in front of, and above you, your own seat placement, etc., every single thing that goes into what that room sounds like to your ears and brain... it will all be captured during the PRIR measurement.
And now armed with the PRIR created that digitally represents every single characteristic of how sound is heard by in your chair in that room, using that PRIR "in the reverse direction" (i.e. for PLAYBACK of any new real audio source) in conjunction with the HPEQ that matches your listening headphone/amp equipment (so that the Realiser can perform the exact adjustements, tweaks, and equalizations needed to compensate for the tonal and volume characteristics of your headphone/amp), you will experience a startling "virtual reality" through your ears.
You will actually believe you are in a specific 3-dimensional physical room with specific physical loudspeakers arrayed multi-channel around and above you that produced a specific "subjective sound" unique to that listening environment, although you are in fact hearing something through 2-channel stereo headphones. It's simply unbelievable, just how indistinguishable the result is through stereo headphones from the original multi-channel 3D-located real loudspeakers. Not just the "physical locations" of the "virtual speakers" cues as interpreted by your brain from what is being fed to it through your two ears by 2-channel stereo headphones, but even the volume, tonal, and balance subtleties of the original listening environment digitally represented by the PRIR. All of this comes through, in the listening experience.
It really has to be sampled to be appreciated.
But again, don't "be cheap" here. Invest all you can in fantastic headphone/amp equipment, because your corresponding Realiser listening experience from an amazing listening enivoronment that you were fortunate enough to be able to capture in a personal PRIR measurement of your own (not somebody else's that you "borrowed", which will NEVER EVER provide the same result as a PRIR specifically measured with your own ears) will benefit correspondingly.
As you can tell, I'm a fan. Ever since 2009 I've been enjoying listening to everything I've watched and listened to (i.e. HDTV as well as movies) via my own personal AIX Sound Room PRIR, and it truly has been like I was there.
