    The PMR (Passive Multi-Vocal Resonator)

    The PMR is a high-resonating system that overlays the musical harmonics.
    This is achieved by:

    • a precisely tuned bronze alloy
    • the specific dimensions
    • the specific design with various angles
    The PMR is not comparable to other resonators available on the market today. These other resonators produce even harmonics, but usually change the tone of the sound with "false" harmonics, e.g. a trumpet should sound like a trumpet, but with the wrong harmonics, it can sound like a completely different, or synthetic instrument. The PMR produces only  harmonics that are perceived by the human ear as pleasant and harmonious. The sounds of music are heard as natural. These "right" overtones are the result of decades of sound research. And by the way... bell bronze is the only material that can reproduce all overtones of the musical scale. This know-how is now being implemented  - world exclusive for the first time as a resonator in the PMR.

    Placement of the PMR:
    The PMR can be placed almost anywhere in the listening room. A comprehensive installation manual is supplied with each PMR. A  telephone consultation is also included.

    The result:
    By overlaying the music with a full scale of multi-vocal overtones, more detailed sound is produced. The music gets more momentum and energy, the presentation of the instruments is more realistic, more solid and three-dimensional. The spatial imaging is increased in all directions. The result is again a natural and authentic sound experience with beautiful sounds.

    Does the PMR fit in my system?
    Yes! Since there are no hi-fi systems with perfect harmonics, the PMR will improve every hi-fi system!

    For every single PMR a two-sand mold is produced before it's cast by hand in a German foundry.

    Production Process:
    The production processes of the PMR and a bell are very similar. Each PMR is custome-made and is produced exclusively by hand in the following steps:

    • Creation of a two-sand mold by means of a "primitive model"
    • Heating the bronze alloy to about 1200 C
    • Casting of liquid metal in the form
    • Controlled cooling off the casting for the production of a fine crystalline structure of metal
    • Manual post-processing and tuning of the cast PMR

      An individual, numbered certificate is included with each PMR.

      The PMR is exclusively manufactured in Germany.

      Dimensions: height 3.4 inch (8.6cm), diameter 14 inch (35.4cm)
      Weight: 12 lbs. (5.5kg) (total shipping weight 19 lbs.)
      Color: natural bronze

    The PMR Premium Mk.2

    The latest development and further improvement of the original PMR is the PMR Premium Mk.2. The difference to the PMR is that the production is even more complex. The improved bronze alloy and extremely long cool-off phases give the PMR Premium Mk.2 even better resonance properties. But the biggest difference is that the PMR Premium has now a thread in the bottom and is mounted on a bronze stand for vertical use that makes the PMR Premium Mk.2 even more effective and indispensable for music lovers who wanted to expierience their favorite music in a lifelike three dimensional way with realistic timbre and dynamics.

    The PMR Premium. StereoTimes' Most Wanted Component 2011!

    The PMR Initium

    The brand new PMR Initium is an outstanding and reasonably priced product - your access to the world of the PMR room acoustic devices. The Initium is about half the size of the PMR Premium (7 inch in diameter).

    You will notice a strong resonance with lots of details and spatial acoustics. The music appears to be more dynamic and full of energy. When it comes to individual instruments, they sound very realistic and seem to have a whole new presence.

    With the help of the Initium, the music gains more space in every kind of way. To sum up: The Initium creates a very authentic and natural acoustic pattern with fascinating timbre. If you already have a large PMR in your listening room add one (or two) Initium for even better three-dimensionality.

    An individual, numbered certificate is included with each PMR Initium. Exclusively manufactured in Germany.

  • Dimensions: height 7.5 inch (19cm), diameter 7 inch (18cm)
  • Weight: 3 lbs. (1.4kg) (total shipping weight 6 lbs.)
  • Color: natural bronze, polished


    Dirk Sommer, HiFiSTATEMENT.net Nov. 2014: NEW
    "...the PMR convinced me fully in two rooms in a total of three constellations. Who craves more definition and a more airy space around instruments and voices should try the PMR. Depending on the situation, you can gain at least the same but usually significantly more with the investment in a PMR compared to the same sum in better cables..."

    Paul Messenger wrote: "...the PMR actually does seem to work. It somehow 'tidies up' and 'sweetens' the sound, so that the music makes more sense and hangs together rather better as a coherent whole. Image focus seemed significantly improved, the degree of gerneral untidiness and 'hash' was significantly reduced and it also seems to add a richness to the proceedings... The bottom line is simply that the PMR somehow manages to make my hi-fi system sound more pleasant and relaxing, so much so that I'm seriously considering purchasing it..."

    Clement Perry wrote: "...a 'mini-me' version to the bigger Novum resonator we all went gaga over. At roughly half the size of the standard PMR, the Initium serves as a perfect companion for placement around the room especially when space is an issue. Adds sparkle and dimensionality to an already excellent product..."

    Stereophile - Recommended Component 2012 Award, 10/2012:
    "... with the PMR Premium in the listening room, ST heard enhanced soundstage, focus and spatial resolution, better-defined bass, and greater vibrancy..."

    Sam Tellig, Stereophile, 05/2012:
    "...the PMR focused my soundstage. Pimped up my power, especially in the bass. Enhanced resolution, especially space. I could hear orchestra members and chamber players breathe, even burb, fart... the sound became single-ended-triode like..."

    "...for me, the PMR imported a bell like clarity to the music,a richness of timbre that rang true. It burnished the sound, especially of brass instruments, but the sounds of woodwinds and strings, too, seemed enhanced-intensified, but not taken over the edge or made in any way shrill. Maybe I'm so old and deaf that I need such sonic enhancement. I was already crazed pre-PMR; now, more so..."

    "...I tried it on my wife, Marina, who, after 20 years with me, has heard it all. Without prompting, she said that she noticed more clarity, greater focus, more vidid sound, superior definition, and tighter, more extended bass."

    Moreno Mitchell, StereoTimes, 01/2012:
    "...when Clement Perry stated "The very ingredients that can fool one into believing real instruments are in the room" in his review of the PMR, I could not agree more. This is exactly what I felt within minutes of hearing this amazing device. Upon reading what Dan Secula and Ron Cook heard via this "singing bowl" did I realize that its effects are universal. Thus far, the PMR has acquitted itself from being some expensive tweak. It is far more powerful than some expensive front-end I've owned. Knowing this, attempting to label the PMR as a mere tweak is criminal."

    "If you're looking to upgrade an amplifier, DAC or even loudspeakers I dare you to give this device a listen first. For the serious audiophile and music lover who demands the best. The PMR is an absolute must. Highly recommended!"

    Clement Perry, StereoTimes, 12/2011:
    "...I tend to believe the addition of a single PMR does as much to enhance the sound of a listening room as an entire arsenal of Ziplex or Acoustic System resonators."

    "...Hard to believe but true: the addition of the PMR makes music sound more truthful and realistic. After more than six months of having the PMR in my system, I cannot think of life without it. Removing it reduces the sensation that real instruments are performing before you on a wide stage... I cannot recommend it more highly."

    Ron Cook, StereoTimes, 12/2011:
    "...I must concur the PMR is one of those all-too-rare products that does exactly as claimed! Suffice it to say, the improvements are NOT subtle and are easily discerned by even the most casual listener. Indeed, I have done A/B comparisons with a number of people, and on each (separate) occasion the effect of removing the PMR was obvious: folks simply cannot believe it. Bottom line, once you try a PMR your system, you will be hard pressed to listen without it. Highly recommended!"

    Dan Secula, StereoTimes, 12/2011:
    "...as much as I enjoyed my system without the PMR, I know now what this device can do to help my system sound even better and I would choose to be without a PMR. In simple terms, the PMR just makes everything sweeter sounding and more organic in a very natural way without any noticeable downside."

    "With the PMR Premium we have a significant, expensive, beautiful tweak that I feel will improve the enjoyment of your music collection. My decision to audition the PMR proved make me feel wonderful considering I had no idea what the results would be. Highly recommended."

    Paul McGowan from PS Audio: "...placed between your speakers, it stares back at you like some piece of Asian dinnerware or ornament. But holy cow, it works! Immediately, vocals get more lifelike, the sound sweeter and easier to listen to..."

    "...I am completely satisfied with how it broadens, deepens and adds solidity to my stereo image. The increased ambiance and detail is amazing. I listened very briefly to my old, PMR-less layout and I will not willingly go back."

    "...must say that I'm simply bowled over with enthusiasm about the way the music has become more real and life-like! Funny thing is I have a tweaked out system that includes (among others) four SteinMusic harmonizers and a dozen or so magic stones...I wasnt expecting such an improvement from the PMR,but it's there...my ears don't lie! I'm thoroughly impresssed!"

    "...I am enjoying my Novum PRM very much! It makes a bigger difference than I ever expected!"

    "...the PMR is absolutely brilliant ...the music has more focus & energy, the most noticable difference for me was the vocals both male & female, it all just sounds so much better..."

    "...just added the 2 HighendNovum PMR Premium to my system....my best tweak ever!"

    "...the PMR Premium surpassed my expectations. A very worthwhile addition to the music room..."

    "...I consider the PMR an essential component in my system now."

    "...as I was extremely pleased with the PMR Premium, I would like to order another one from you. It certainly enhanced the sound of my stereo system..."

    "Dear Alfred, after I put the PMR Premium disc on my JL F113 which sits in the middle of my Acapella Violin Cello MK II horned speakers less than a foot behind them, the affect was immediately dramatic. The synergistic effect of focusing the sound and smoothing out the music made me grin from ear to ear. I am totally pleased and feel the investment was worth it..."

    "...after living with the two disc set-up (PMR Premium) for less than a week, I can say that my listening experience has truly been permanently transformed... wouldn't have believed it until I heard it myself. I never thought these things could do so much to "harmonize" the room acoustics."


    The PMR LP ONE follows the same principle and concept as the other multi-vocal resonators (PMRs) and therefore, in addition to enhancements to the sound of the turntable, offers a degree of tonal value in the room acoustics as well.

    Its main task is to achieve, as record weight, exceptional sound improvements to the analog system. This is accomplished by its alloy, casting type and calculation of form with FEM (Finite Element Method).

    Even minimal interferences in the audio signal and unwanted resonances are removed to a high degree by the LP ONE as a result of the vibrational properties of its special bronze alloy and material properties. The turntable's drive is steadied and runs stress-relieved like never before. Therefore the audio signal cannot pass on "contaminations" to the listener. This provides a highly pure audio signal in a previously unheard fidelity.

    The listener experiences for the first time a product that performs two essential functions necessary for the perfect-sounding vinyl record:

  • A special weight with optimal material properties
  • A room resonator - either alone or in addition to other PMRs

    The discerning listener hears more sounds, body, strength, charm, and a natural decay.

    Dimensions: The LP ONE measures 2.4 cm in height - the diameter is 8.9 cm at the top and 4.4 cm at the bottom. With a weight of 230 g the LP ONE provides ideal properties for its function as a record clamp/weight.

    Reiner Mueller, Germany, Dec. 2011, with "ZU Audio Essence" loudspeakers:
    "...when I used the spikes made of bell bronze, the entire sound changed. Clean, crisp bass all the way down to the lowest frequencies. Crystal-clear, artifact-free highs - voices with authentic sound reproduction and presence, distinct increase in range of frequencies and greatly-improved soundstage. Clear and distinct separation of the individual instruments. Open and direct listening pleasure, even at low volume levels. Stable-leveled and clear sound, at volume levels far louder than normal listening room volume..."

    "To sum it up: With the bell bronze spike, Mr. Jungblut was able to make a product that is able to greatly improve most sound systems. These spikes provide great listening pleasure and demonstrate that it's better to improve your current system with economical tuning devices rather than to constantly purchase costly new equipment and experience the frustration that often accompanies doing that..."

    Customer feedback:

    "...the spikes have been installed since yesterday and what should I say ... simply sensational!"

    "...with these spike made of bell bronze the music sounds much more vibrant, energetic and detached, as though it was played before with the hand-brake on.... The decay of the tones was extremely improved, especially in music played on acoustic instruments. Voices had an intensity like never before. Altogether, the music sounds much more ethereal, with new, glorious overtones that have a pleasing effect on the ears."
