$1,975 audiophile maple block set
Remember the Silver Rock Beech Knob, claimed to improve the sound quality of high-end stereo equipment? A simply-lathed chunk of wood, it was pitched at audiophiles who should know better, but don't. The product page went 404 a while ago
, for whatever reason. But worry not, listeners! Pure Music Group
offers an "Acoustic System Phase Corrector," a maple block that appears to operate on similar principles. Best of all, it costs only $150.
The Acoustic System Phase Corrector may look like a simple instrument grade maple block but its inner workings are more complex. When you walk around your listening room you will notice pockets of greater energy density. One of these energy pockets occurs between the loudspeakers and is concentrated at the interface between the floor and the front wall. From the listening position the result is a blurring of the phase coherency. The phase corrector, as its name suggests, attempts to correct this phenomenon by disrupting the energy pocket near the floor/front wall interface through a combination of resonance and diffusion. The degree of resonance can be altered by varying the distance between the phase corrector and the front wall.
Clever prank? You decide. And they're just getting warmed up:
What you see above is the Acoustic System Room Package
, comprising at least 10 resonators and one diffuser, which together apply the same revolutionary technology to all four walls. On the front center wall, one places a resonator near the floor, a "Special Gold" resonator slightly above tweeter level, and so on. As a result, "the front wall tends to disappear." Similar executions on other walls provide bass definition, widen the sound stage, remove blinkers, and clean up the overall image.
You may purchase the two grand package in stages, "as budget allows." Be sure to give the resonators 4 days to reach their maximum potential.
Stocking stuffer! For only $45, one may grab a single Acoustic System Diffusor (right), whose effect is akin to "the sound holes on a stringed musical instrument." Place it on window panes or A/C units to reduce their undesirable sonic impact. Note that the orientation of the woodgrain in the diffusor itself can influence the sound.
There is much else to love at Pure Music Group's website. Don't miss the $172 CD stabilizer
, made from isostatically molded graphite.
