Google "Machina Dynamica" And take a look at some of this company's outrageous products. He sells a $60 phone call the improves not only sound but video too! He claims to be some sort of scientist, I thinks hes just a clever con-artist.

Did you know the pebbles are a very small glass jar of rocks? How is it possible for rocks in a glass jar absorb sound?

So check out this "White Paper" one some magic rocks/pebbles that improve the sound of any audio system. These rocks do not connect in anyway to the audio system but still have an effect? Hummmmm I would love to hear what some of you have to say. "Brilliant Pebbles is an original concept of Machina Dynamica. Brilliant Pebbles capitalizes on two specific properties of mineral crystals; these properties - vibration absorption and Radio Frequency Interference/Electromagnetic Interference (RFI/EMI) absorption - are the consequence of atomic mechanisms in the crystals' highly symmetrical structures. The Original (Large) Brilliant Pebbles is a 3-inch tall glass bottle containing minerals & stones of various types, each possessing a unique, highly symmetrical crystal structure. The newer "Mini" and "Mikro" Brilliant Pebbles are considerably smaller in size (the "Mikro" is only 1 1/2' tall and 5/8' diameter), contain a wider variety of crystal types and have different applications than the Original (Large). An array of highly-specialized, proprietary preparation & assembly procedures contributes sigtnificantly to Brilliant Pebbles' effectiveness. Brilliant Pebbles functions as vibration absorber or RFI/EMI absorber, depending on application. Some solid materials - most notably, metals & minerals - are comprised of atoms arranged in highly symmetrical, geometric structures called "crystal lattices." These structures are adopted because they constitute the lowest energy states of the atoms in the materials. A simplified crystal lattice structure is illustrated below; electric binding forces are shown interconnecting the atoms in the lattice. A 3-D image of the crystal lattice below can be visualized by allowing your eyes to cross slightly (de-focus) while viewing the two green cubes from a distance of about 18-20 inches from the computer screen. A "virtual" 3-D green cube will form between the other two 2-D images. A more complex arrangement of molecules and atoms within a lattice structure is shown below for Jadeite (sodium aluminum silicate). The temperature of a mineral crystal, as for any material, is proportional to the average kinetic energy of its atoms. External energy forces the atoms in the mineral crystal to move more energetically (i.e., gain kinetic energy); applying heat or mechanical or acoustic energy to the crystal increases the kinetic energy of the atoms and raises the temperature of the crystal. To illustrate how mechanical (including acoustic) energy is converted to heat in a mineral crystal, consider the extreme case of a crystal at a temperature approaching Absolute Zero (-459 degrees F), the lowest possible temperature, when atoms in the crystal lattice maintain their lowest energy positions with very little or no motion whatsoever. Any mechanical energy (e.g., acoustic waves or mechanical vibration), applied to that extremely cold crystal material forces the atoms to begin to vibrate around their equilibrium positions in the lattice - the greater the energy applied, the more energetic the vibration of the atoms. At the same time, the electric forces binding the atoms together begin to stretch and compress slightly to allow for the higher energy configuration; each atom acts as if it were connected to its neighbors by extremely small springs (see animation below). At room temperature the process is the same: energy applied to a crystal at room temperature increases the kinetic energy of the atoms and the potential energy of the compressing/stretching "virtual springs" (electric binding forces). Since the temperature of the crystal is a function of the kinetic energy of its atoms (same as for any material), it follows that the crystal is simply converting mechanical or acoustic energy to heat. The reason Brilliant Pebbles is such an effective "node damper" (energy dissipater) in audio applications is that it transfers energy more efficiently and rapidly than virtually all other energy dissipation type devices. The typical motion of atoms and spring-like electric binding forces in a crystal lattice are illustrated below; note in-phase and out-of phase modes of oscillation of the atoms. Major sources of unwanted acoustic energy are corners of the listening room, where surprisingly high sound pressure levels are produced when music is playing - these levels can actually be 8-10 dB higher than the average sound pressure level in the room -- about eight times higher! Room corners project acoustic energy out into the room when music is playing - as if there were many additional speakers in the room interfering with the pure signal of the primary speakers - producing phase distortion at the listening position ("comb filter effect"). For this reason, room corners are outstanding locations for the Large Brilliant Pebbles. In the corner on the floor, even a carpeted floor, Brilliant Pebbles significantly improves dynamic range and lowers distortion of the audio system. While Large Brilliant Pebbles in only one corner can produce excellent results, a bottle in more than one corner usually produces the best results. Two other excellent locations for the Large size bottle are (1) in front of and to the outside of each speaker and (2) midway between the speakers in the plane formed by the front faces of the speakers. The new Extra-Large size bottle is intended for corners of larger rooms and on top of larger speaker cabinets. Wherever unwanted mechanical or acoustic energy is produced in the audio system - speaker cabinets, CD/DVD/SACD players and tube amplifier output transformers - are good locations for Brilliant Pebbles. A Tube Trap produces (unwanted) mechanical energy during operation and a Large BP on its top surface improves Tube Trap performance ("A Better Tube Trap," you could say). The performance of (conventional) speakers is usually improved by placing one or more Large BP on the top of each speaker cabinet. A large BP on each output transformer of tube amps is also usually effective. A Large or Mini BP can be effective when placed on the armboard of a turntable. In addition to vibration dissipation characteristics, Brilliant Pebbles exhibits RFI/EMI absorption characteristics. This RFI/EMI absorption, like vibration absorption, is accomplished via atomic mechanisms in the crystal lattice. Electromagnetic fields are produced by electronic components and elements that can interfere with audio system performance. Each mineral type in the Brilliant Pebbles bottle possesses a unique, frequency-specific (i.e., narrow band) absorption characteristic; consequently, the variety of mineral types in a bottle provides a much wider band of RFI/EMI absorption. This electromagnetic absorption property of Brilliant Pebbles is especially evident when the smallest size "Mikro" bottle is placed on top of Quantum Symphony or Quantum ElectroClear line stabilizers or placed in proximity to small electron tubes or the volume control knob of a preamp. Over a period of time, Machina Dynamica developed four sizes of Brilliant Pebbles, each addressing specific problems in the room and system: The 3-inch Large Brilliant Pebbles is intended for speaker cabinets, tube traps, room corners, satellite TV receivers and output transformers of tube amps. The 2 inch "Mini" Brilliant Pebbles is intended for the top of CD/DVD/SACD players, top of speaker cabinets and proximity to small electron tubes. The "Mikro" BP (about 1/4 the volume of the "Mini") is intended for proximity to electron tubes, on Quantum ElectraClear & Symphony line stabilizers and attached to interconnects and digital cable. The newer Extra Large size was developed for the corners of larger rooms and for the top of speaker cabinets. Experience in a great many systems has shown that Brilliant Pebbles can sometimes effect the sound in unpredictable ways. So, some experimentation is usually necessary to establish ideal locations for Brilliant Pebbles in a given room/system. A typical room/system will yield quite a number of "ideal locations" for all sizes of Brilliant Pebbles. Brilliant Pebbles is capable of dramatically lowering audio noise and distortion - perhaps especially in systems where great pains have been taken to ensure the highest possible performance."
