  • Re: Thoughts on SDA's...

    I would like to add a link that gives a good pictorial description as well as a highly regarded reviewer back in the day and his explanation based on discussions with Polk at the time SDA's were released. I should have posted this earlier but I forgot about it.

    I see someone didn't read the explanation of what SDA is. Once again, it is not an effect. Non-SDA stereo speakers would be more accurately described as having an effect.

    Non-SDA speakers are used in virtually every recording mastering and mixing studio, therefore soundstage and stereo effects are optimized in house for normal non-SDA speakers.

    Your comments are based on sales literature and the "White paper" from Polk and are in conflict with real world experiences with recording, mixing and mastering personnel.

    The Polk white paper ignores certain facts about how actual recordings are made over the last 4-5 decades and instead concentrates on a theoretical recording style that has the listener sitting in the middle of a concert hall, and hearing the sound and scope of the hall itself.

    Since almost all recordings are completely created in studio, and the resultant sound stage and stereo effect are done with normal speakers, similar to what is used in home, the SDA effect may be quite enjoyable, fun and even sound better, but it will never be a more accurate representation of what the recording engineer intended.


    It's laughable that you think 2 channel stereo is the correct way to reproduce life like sound. It's not, It's incredibly flawed. SDA's provide a way to correct a few of the blatant flaws in the 2 channel mix down of a multi faceted real life event. Our ears and brains are much more sophisticated than to settle for a 2 channel mix down.

    Also SDA IS a much more realistic and accurate presentation of the real life event, not stereo. Engineers can be incredibily heavy handed in mixing and mastering for a single particular attribute. Think of them as the same as a photographer using photo-shop to manipulate their photo's for the intended final result. Not realistic at all, but altered, manipulated to produce an intended outcome other than the real thing.

    Are SDA's perfectly recreating the real event, no, but they are much closer than the same played in 2 channel stereo.

    Stereo is an illusion.

    In your enthusiasm for SDA you omit one extremely important thing.

    There is no actual "Real life event" in the vast majority of recordings.
    They are mostly studio created from bits and parts and each part has is own placement and ambiance added electronically.

    Are you trying to say that something with an artificial sound stage can be improved, when there was no actual imaging and sound stage to begin with?

    So your saying Abby Road, Stargroves, Olympic Studio, Sun Records, Headley Grange, Polar Studios and a plethora of other recording studio spaces that all have their own sound are exactly the same, cookie cutter recording places that have zero influence on the "real" musicians, playing "real" instruments. It's all in the mixing and mastering illusion that creates the sound? So they could record in the bathroom and it would all sound the same?

    As an exercise look up Led Zeppelin - Headley Grange - When the Levee Breaks and tell me the real life event doesn't have a sound of its own that no engineer could recreate. They tried and tried and failed to "create" this sound in the studio. That recording sounds much more realistic on SDA's then it does on any other speaker I've heard to date.

    Your thoughts on this subject are your own illusion since they have no basis in reality.

    2 channel stereo is an illusion since it's been mixed and manipulated down from multi channel recordings. Do you know why? Because that is the standard consumers are willing to accept and can be mass produced for the end consumer to turn on and push play. Not because it's better or more natural, but because it a compromise (standard) that has been the most accepted therefore the most profitable.

  • Re: Going Digital finally...

    That begs another thing to ponder, just because something is a good deal, doesn't mean it sounds the best or is the best fit for a rig?

    We all want to be economically smart with purchases. It seems digital technology moves pretty fast so buying older products may or may not give the best result. I know I was surprised at what some of the new chipsets have to offer.

  • Re: Should Lasareath talk about audio on the Polk audio forum or electric cars?

    That was the other point I was going to make.

    Sal, really hasn't participated in audio discussions for quite awhile now. I'd be more willing to let it go if he was a contributing member, beyond the EV rhetoric, once in awhile. You can only garner so much goodwill based on your past interactions. At some point the scales are going to tip (as we've started to see).
