|Tweak du Jour - Black Ravioli Pads
|Are the Black Ravioli
Pads stuffed with black magic ...
or complex BS ?
If you are looking for a great pasta recipe, this is not it. Neither am I about
to evaluate the pasta known as ravioli. However, I'm about to tell you how to
cook up, perk up, grade up an audio system with the help of these things they
call Black Ravioli. They are made in Scotland, designed by Derrick Ethell and,
although they are not edible, they are designed to complement and enhance the
performance of audio and video components.
The Black Raviolis share the namesake pasta's shape but are filled with an unknown
rubbery substance wrapped tightly in a black nylon fibre pillow. Nothing in the
Raviolis' appearance prepared us for the experience when Jody Hickson of Globe
Audio Marketing got on his hands and knees and began placing them under everything
My first experience with these little thingies was at out ex-president, Sol Scharf's
country house where a major system set-up was being finalized in a dedicated
listening room. His system employs two sets of Orpheus monoblocks, a WLM subwoofer
and a pair of Gran Viola speakers (reviewed in Vol.16, No.4) powered
by a Bryston 4B SST (reviewed in Vol. 13, No. 4) and an Audio Aero Prestige
SACD player (reviewed in Vol. 17, No.2) also used as a preamp. The balance
of the system included the Exact Power EP 15A power line conditioner (reviewed
in Vol. 16, No.3), and a whole mess of Nordost Valhalla cables (reviewed
in Vol. 13, No. 2). Although a resonance/vibration-inhibiting shelf as well
as Core amp stands (reviewed in Vol. 17, No. 1) were in the set-up,
Hickson began by placing the BRs under one pair of amps and asked us if we noticed
any sonic changes. Not only did Sol and I hear the addition to the system, we
both agreed that it enhanced an already great-sounding system; one that I thought
needed no additional tweaking. Next, Hickson placed four more Raviolis under
the other pair of amps and - bang - the sound took on an even more engaging quality.
Three more BR were placed under the CD player — and again we noticed the
improvement. Every time a BR was added to the system, the sound got better – it’s
||Well I was impressed enough to ask for more info and some Black Raviolis to "play
around with". Back in Toronto, Hickson came over to my house, got on his
knees once again and I clearly heard improvements every time a BR was added to
the in-house system. We began with four BRs under the EAR 899 amp. This resulted
in a more elevated sound stage and better-defined space between instruments and
voices. Later, four more BRs were stacked under the amp, which further improved
spatial elements on the sound stage, but also added a touch better resolution
to fundamental (musical) notes.
Next, we placed four BRs under the CD player (another EAR product, not yet reviewed).
This seemed to free the sound from the system's loudspeaker enclosures, taking
up the overall sonic refinement by a few notches. Adding another set of BRs didn't
result in added improvements, possibly because the CD player was already resting
on a resonance-inhibiting shelf.
|The next step amazed me
inasmuch as I can't account for it. A single BR was placed between the
CD player’s RCA inputs and another on the amp's outputs. This "freed" the
sound from the system's enclosures ever-so-slightly, adding resolution
to the sound.
Having placed even more Raviolis around, under and between the system components,
I decided to leave them there for a few days and listen to some of my favourite
music. About three days later, I removed them and listened to the system again;
and their absence was immediately noticed.
Synopsis & Commentary:
The Black Raviolis will be a revelation to all those who truly think
their system doesn't need improving. The BRs aren't a tweak that
modifies or mutates the sound of a system so they won’t improve an inadequately performing set-up. Rather,
they are to be used to heighten the performance of a system that has been carefully
assembled and is already performing well. The result will be gratifying to the
demanding, experienced listener, as the Raviolis reveal the potential of the
wonderful world of high-end audio. In light of their price, the Black Raviolis
are certainly a low-cost, high performance accessory that will spice up the performance
of an audio system. Imagine, if you will, standing on a hill admiring a beautiful
landscape. You climb a ladder or a tree and in this elevated position, you'd
see further into the scenery. That is exactly how the Black Raviolis work. They
allow a better look into the musical landscape, without, however, altering its
appearance. If you haven't tried the Black Raviolis, you'll not miss them in
a good audio system. However, once you have had the opportunity to hear your
system totally "raviolied" it will become clear that your audio will
go from good to great with the help of these little tweaks - I kid you not.
The Black Raviolis are simply one of the greatest tweaks I have run across
in over two decades of reviewing.

The aim of the designer, Derrick Ethell, was - and I paraphrase, "to
sink all vibrations to absolute ground". A big claim to make,
but the BRs do just that and I find their effectiveness approaching
audio wizardry. These small pads are extremely efficient at dissipating
the disruptive energy that is constantly being generated and stored
by system components and their weight-bearing bases (stands or
According to Derrick, the Ravioli pads are completely passive and cannot modify
the designed performance of any component. However, there can be significant
differences in how individual components will react when the Black Raviolis are
applied to a system. The pads are inconspicuous when in place and can accommodate
the weight of a wide range of equipment. However, they will be damaged by spikes.
The Black Raviolis are designed to ensure a firm connection between equipment
and its support.
They are deliberately flexible so that the component and pad
can achieve optimum integration. It is recommended that, as a starting point,
the pads be placed under all four feet of the component which is sitting on a
flat non-resonant platform. Three point support of equipment is generally inferior
to four point support and is not recommended. Additional benefits may be achieved
by stacking Black Raviolis under specific equipment. However, it is recommended
that before stacking is considered, single BR pads be installed throughout the
Derrick states that "there should be continued gains in performance
while the components and the Raviolis settle into their optimum position".
The integration time can vary from one to five days, depending on the number
of components, their weight and the number of Raviolis in the system. Although
my auditions with Raviolis in place revealed immediate improvements, it is said
that A-B comparisons do not reflect the full benefit of the Raviolis until after
the break-in period when they have settled to their maximum operating condition.
Based on my experience, I believe that placing the BRs under the most sensitive
component, such as the source component(s), renders the most conspicuous improvement.
However, Derrick claims (and I take his word for it) that benefits will also
be realized by placing Raviolis under other components, such as transformers.
