Reviews and Commentaries for More Direct to Disc Recordings
Many years ago we had discussed the polarity issues associated with this record:
According to the liner notes, this album has its polarity reversed. They tell you straight out to reverse the positive and negative at the speaker terminals for the best “transient response and spatial clarity.”
That out of phase quality is as plain as the nose on your face when you know what to listen for. There’s an unpleasant hardness and hollowness to the midrange, a lack of depth, and an off-putting opaque quality to the sound. The top gets dull and the bass gets weird and wonky.
With our EAR 324p phono stage, the click of a button reverses the polarity. I can’t tell you how handy it is to have such a tool at your disposal. Checking the polarity for Discovered Again couldn’t have been easier.
But get this: most side ones are NOT out of polarity. How about them apples! We could not have been more shocked. Here is the most famous reversed polarity audiophile recording in the history of the world, and it turns out most copies are not reversed on side one at all.
I did not do the shootout for the album, but I wanted to check on the polarity just to hear it for myself. I must admit I had to go back and forth a number of times, using my favorite song on the album and an old Demo track from back in my earliest days in audio, the mid- to late-’70s: Keep Your Eye On The Sparrow.
Harvey Mason’s super punchy drum playing catches your attention right off the back. A tambourine comes along in the left channel at some point. Lots of bass. Rit’s guitar in the right channel and Grusin’s keyboards in the center fill out the soundstage. The ensemble is on fire.
Evaluating the sonic differences of the individual instruments in and out of polarity had me confused. A typical conundrum: Should the tambourine be smoother with more body, or brighter with more harmonic overtones? Which is right? Who can say definitively?
It was only after about fifteen minutes of playing the album, switching the polarity back and forth, that the penny dropped.
Focussed on an individual instrument, I could hear it just fine both ways. But then I noticed that with the polarity reversed the group got vague. The images seemed blurrier, less defined. If I relaxed and just stared into the middle distance and let the music flow, the band seemed to be more jumbled up and messy.
That was the key. The obvious change when the polarity was wrong was a loss of image specificity. Flipping the record over to side two and using my new “lens” to hear the difference with the polarity changed, it was obvious when the polarity was right or wrong.
I have experimented with polarity on scores of records. Certain effects on certain records are unmistakable. But these effects seem to vary a great deal from title to title. Grusin’s brilliant direct to disc recording initially had me at a loss. With a little experimentation, the improvement in the sound with the correct polarity became evident over time, as it always seems to do. Thank god I didn’t have to change speaker leads the way I used to in the old days. (more…)
