Our 2012 CES/THE SHOW exhibit featured as co-exhibitors:
Wyred4Sound/Ampzilla and Wywires
Wyred4Sound showed its full line of preamps, power amps, DAC’s and other surprises. Wywires had on hand the latest incarnation of its superpremium Speaker Wire plus a full set of its top of the line balanced interconnects.
VMPS debuted the Series II edition of the RM50 speaker system complete with your choice of digital controller or outboard analog crossover.
This year we had more variety and number of performers for our one of a kind live-vs-recorded demo. Scheduled to appear: the Merv Harding Quintet featuring legendary alto sax/flute/clarinet player Fred Haller, a James Bongiorno solo jazz piano recital, and three guest vocalists.
We want to thank everyone associated with our Live vs Recorded demo in the Lake Mead ballroom of the Flamingo this year. It was a tremendous amount of work and expense, and we might have fallen flat on our faces.
We took a huge risk hiring the Merv Harding Quintet (piano, alto sax, trumpet, acoustic bass, drums plus male vocals) to play for us. The sound pressure and dynamics of these great players (whom I encouraged not to hold back in the least), particularly from the drumkit, made our heads spin. We were quite sure at first that our record/reproduction chain would not be equal to the task. After hearing the Merv Harding Quintet do sound checks with levels over 100dB SPL at a listening position about 15 ft away, it seemed we were dead ducks. High end speakers simply aren’t designed to keep up with live sound sources in a room that size (26x60x9ft). That we did so, and with great accuracy, was a relief and a real accomplishment.
We needn’t have worried. After several awful sounding takes with the musicians too far off mic, we ended with bass, trumpet and sax clustered around the stereo mics, piano about four feet away, and the drumkit about eight feet back. The Series II RM 50 played back the full range of sound at live levels with plenty of headroom, no distortion or clipping of the Ampzilla monoblocks, and no coloration we could detect. It was a triumph for all involved.
Kudos to our recordists Jim Harger (hi-rez) and Dave Housteau (double DSD), our musicians, E.J. and Clint from Wyred4Sound/Ampzilla, and Alex from Wywires for a job done to perfection.

VMPS Patented Constant Directivity WaveGuide
We are introducing the new generation of Constant Directivity Wave Guides, as defined by our US Patent.
The new guides are simple add ons that attach directly to the mid and tweeter panels. They are lightweight, lack baffles, are inexpensive, eliminate treble rolloff, exhibit less than 1dB insertion loss, and may be used with planar drivers other than our own, such as DG Neo 8 and Neo 10, Hi-Vi, and EMIM's. The waveguides can be used on dome tweeters and ribbon supertweeters, but are not designed for cone midranges. No crossover adjustment is required.
Beyond improving directivity, the new CDWG's positively influence sound quality in other ways, such as midrange smoothness, bass solidity, naturalness, and of course, dispersion.
The principal of the diffraction slot is well known and is the basis for almost all constant directivity devices for 30 years now. With planars, unfortunately, simply making them narrower is no solution, as their sensitivity would be very low if made wide enough (2/3") for CD dispersion up to 20kHz.
If you mask off part of the diaphragm to make a narrower slot it causes a lot of energy to be reflected back into the driver, and the resulting IM distortion is quite objectionable.
Our solution was a damped slot, with substantial absorbtive as well as reflective components. This is what made our CDWG patentable over the prior art. Many opponents objected to the granting of the patent, but after 5 years, we prevailed.
In the second generation CDWG, the device is reduced to its simplest components and attached directly to the driver frame. The opening here is about 1", corresponding to a 12 kHz CD characteristic. This is fine for our panel, which rolls off mechanically at that frequency. Only half the diaphragm is forced into constant directivity, and then there is a gradual transitiion to narrow dispersion. In this fashion, there is little or no audible treble rolloff for the on-axis listener, and insertion loss is very low. The panel now mimics the cardioid dispersion pattern of many musical instruments and voice. The difference in disprsion patterns is what makes speakers sound so different from live sound as far as directivity is concerned.
A similar CDWG with a narrower opening, designed for planar tweeters, is also available, as are antiffraction masks for tweeters that are already narrow enough for CD behavior to 20 kHz.
It takes a pair of CDWG masks to treat a single panel or tweeter, and these are $20pr. You would need two pair to treat the panels in a pair of single panel speakers like the 626, or the single tweeter in any FST speaker.
VMPS Live vs. Recorded at The Home Entertainment Show 2011 - Las Vegas
Jazz singer/songwriter/playwright ("Stella Rising", "Miami") Napua Davoy performed in the VMPS exhibit booth at THE Show (CES) Jan 6-9 2011, and cut a live album during the course of the Show's four days.
Venue was the Red Rock 1 ballroom (27x50x9') of the Flamingo Hotel. We planned to simulcast the event on a Las Vegas FM jazz station. Hi-rez for pay downloads will be immediately available on Napua's website www.bravecoolworld.com. We also simultaneously cut and sold a limited edition autographed CDR of the event to Show attendees.
Napua wrote original charts for our large combo of alto sax, flute, clarinet, piano, string bass, duo guitars, percussion, and full drumkit.
Playback was a real live-vs-recorded workout for the RM50 speaker system and Ralph Karsten featured latest versions of the Atmasphere MA 2 220W OTL monoblocks and some new gear.
Unlike our 2008 and 2009 demos, this time we were not trying to reproduce the live sound exactly as the audience would hear it. Instead, we were making as good a live album as we could for Napua Davoy, and that involved a stereo pair of mics in MS configuration for the band, a separate mic on guitar, a stereo pair under the piano lid, and a vocal mic, all mixed on the fly. In playback the voice was much more prominent than in the live sound, since the vocalist was facing away at a ninety degree angle to the audience. Fortunately the RM50 reproduced the live sound with virtually complete accuracy, and was also killer on CD playback during the Bybee Music Rails DC filter demos.
The price bar has been dramatically lowered for High Enders looking for State of The Art speakers. There are many fine systems out there at all price points now. With the RM50, you get unsurpassed sound quality at a price many can actually afford. The $100k and up speakers I have heard from other manufactures do no better, and many don't come close.

Our live recording of Napua Davoy and her Braveoolworld Band should be available soon. Contact us for price and availability.
We want to assure those of you who dislike digital processing that an all analog version of the RM50 w/Bybees is available at the $14,900 price point, in single amp or biamp configurations. We prefer the modded DCX for its flexibility, neutrality, and built in room and speaker correction.

Introducing RM50 - Live Music reproducer
Anyone who red 2009 CES reports about our live vs recorded demonstration at the Zeus Ballroom could learn much about the challenges we faced. This was new territory and many of my assumptions coming in proved incorrect. But, that's why you go exploring in the first place--it's the Undiscovered Country, an audio frontier.
What struck me immediately about our demo is, although we could EQ in the frequency domain, adjust delays, treat the room, and have good equipment. we were not reproducing the dispersion patterns of live instruments properly with our dipole V60. Instruments radiate either omnidirectionally (strings, keyboards, percussion) or in cardioid pattern (voice, winds, brass). Two types of speaker mimic these patterns: the omni and the bipole. Of the two, the bipole is less problematic in the average listening room because you can control the amount and incident angle of reflected energy with baffles and waveguides.
Bipoles require a very sturdy cabinet and cannot be done well on the cheap. Also, I wanted more treble surface area to help overcome the HF absorption of large listening rooms like the Zeus. An array of tweeters was necessary. Side by side arrays (line sources) need drivers in very close proximity in order to radiate as a coherent source, so the tweeters would have to be short and narrow, placed as close to the mid panels as possible. The integral bass section would have to be large and powerful. The entire design shouts out for execution at the highest quality level, better than what we had done before.
We also needed a system that could take full advantage of modern DSP and be user friendly and accessible. Just dealing with typical room problems is impossible without such processing power. This has little to do with the quality of the speaker - no uncorrectable speaker we know, regardless of price, would have reproduced live music properly in that environment. Simple "linearity", "accuracy", "time alignment" or fixed off-axis dispersion patterns would not do the job for every listener, and we had 30 of them to make happy.
Sound reinforcement systems ignore virtually all these considerations and focus on deliving adequate sound pressure levels to a wide audience. We had to do this too, but without the coloration of horns or many other types of waveguides. Indeed, the task at hand was daunting and would require a complete rethinking.
In the RM50, a true Live Music Reproducer, the challenges have been almost entirely overcome, as we demonstrated at THE SHOW. We had have live vs recorded demonstrations all four days with solo piano, voice, winds, string bass, percussion, guitar, bass drum, just about everything. And we played your CD's on request. They sounded much closer to live too.
Audiophile life has become easier now, its frustrations far fewer, satisfaction levels much higher. Listen to RM50 and see if you agree. -

VMPS at The Home Entertainment Show
2010 - Las Vegas
It is a great pleasure to announce that VMPS has partnered with Ralph Karsten's fabulous Atmasphere OTL tube electronics for another live-vs-recorded festival of music and sound at THE SHOW, Flamingo Hotel Las Vegas, Jan 7-10.
Those with good memories will recall debuting the VMPS RMV60 speaker in Jan 2006 at the St Tropez with the Atmasphere MA2 220W OTL monoblocks. This upcoming CES will feature the Mk III version of the MA-2, the MK III version of the 18 tube, two piece MP 1 Atmasphere preamp, and some extra goodies to be announced. Our source will be vinyl, CD, and live music.
Best of all, we have obtained the largest and finest demo room at CES: the 28x62x9ft Lake Mead I and I, strategically located at the top of the escalator just to the right of THE SHOW's registration desk. You can't miss it. There will be live and recorded playback nonstop all four days, with at least 30 seats available, so come by any time if you're in town.
This time we are bringing our own 24/96 and DSD recording equipment with tube condenser mics, and will employ two to five channels depending on number of performers. CD's of the event will be burned and made available to showgoers on the spot. There will be plenty of audience participation, not just the passive listening common to hifi shows.
At the Alexis Park this year we learned how to do a convincing live-vs-recorded demonstration and this time will be even better.
Below are links to videos of five performances from 2009 event. After you listen to "Jerusalem of Gold" live, stick around and hear it again reproduced via the two channel DSD recording over the Ampzilla/VMPS V60-VSS speaker system. You can tell that, even with the different balances imposed by the use of the single stereo mic, we really nailed the playback! Fidelity is outstanding.
There are four other cuts from our 2009 demo available to click on here. Brian Cheney introduces all the tracks and play percussion, with Chris Salocks on piano, Bill Bailey on string bass and Fred Haller on sax and flute.

The openness and air that a rear facing tweeter can bring to the sound is well known. To meet those preferences, we now offer the
Ambience Add-on Tweeter.
This is an add-on
usable with all our speakers (except the RM V60) that is freestanding and complete with crossover and user-adjustable level control.
This can stand on top of a speaker or be attached to the back baffle with double-sided tape. It consists of our spiral ribbon tweeter with a 5kHz xover built-in mounted in a black MDF enclosure 4x4x1.5" deep.
It simply plugs in to the back of any speaker we make. The user can direct its output to the rear or side wall, or even the ceiling depending on room acoustics and his tastes.
Rear facing will have the sonic virtue of creating more airy depth to the sound.
Side firing will offer wider appearing soundstages.
Ceiling orientation will create a bit of height to the stage.
We will include this tweeter in the SDE versions of the RM30, RM40 and RM2 at no extra charge for the next 90 days, (till May 30th) thereafter $129pr additional for the built in option.
The built-in ambiance tweeter is flush with the back baffle and fires rearward.
This is also GREAT for the L&R Mains and Surround speakers for HT use.
The user adjustable volume control allows you to achieve that "perfect" blend.
Introductory Pricing = $169 (MSRP will be $249)
Or
Built in to your new speakers = No Charge till after May 15th then $129.
SDE speakers
SDE stands for Special Digital Edition,
meaning that the largest part of an analogue
passive crossover is replaced with digital
active crossover. We now offer all of our
speakers also in SDE configuration, which
requires bi-amping. Active crossover unit
(Behringer DCX 2496) can handle six channels, so
it can be also used for any pair of main
speakers together with any pair of our
subwoofers.
Please contact vmpsaudio@aol.com
for details on configuration and pricing.
Special
priced models
Continuing from a first special for our 30th
anniversary, we now offer several loudspeaker models in
limited quantity and special configurations at incredibly low
prices.
626R Jr ($975/pair), LRC Jr
($549 ea.), RM2 Jr ($1999/pair) and RM40
Jr ($2999/pair). There is also a special
price for SDE version of RM30 (both M & C). All Jr models can
be upgraded with most of available upgrades.
Please contact vmpsaudio@aol.com
for details on configuration, exact pricing and
available finishes.

New 6.5"
woofer
Our new 6.5" woofer, found in the RM 30,
626R and RM V60 speaker systems, is an
evolutionary development of a driver we first
built 5 years ago. It is a true lowbass, not a
midbass, and as such features a four-layer
1.5" voicecoil, 7 mm of Xmax, a woven
carbon fiber cone with natural rubber surround,
40oz magnet, and 250W of power handling.
It is quite simply the finest quality, and best
sounding, such loudspeaker ever produced. Made
in USA.
VMPS at Rocky
Mountain Audio Fest 2006 (Denver, Colorado)
VMPS exhibited at RMAF from Oct. 20th to 22nd
2006. On exibithion were RM30 (MLS Piano Ebony
finish, OXO outboard crossovers) and Larger
Subwoofer.
New
"Piano MLS" finishes
RM40 in MLS Piano
Ebony (with piano black CDWG)
The finish has a shimmering, tactile, liquid
quality quite unlike the "under glass"
look of many coats of clear gloss lacquer over
veneer. You expect ripples when you touch
it.
The finish is achieved by applying glaze over
the satin finish and hand-buffing for 2 hours.
RM30 in MLS Piano
