BRENDA
When I started my design process of designing
an RCA type interconnect connector that would accommodate bare wire,
it occurred to me that with the Monopoles®,
WireTailsTM
and WireGrubsTM
within the signal chain the final item to assist the listener to enter
into the ‘private space’ of the original performance would be a bare-wire
interconnect connector component.
One of the residents on the farm was a very private
‘person', we called her Brenda. No one could get closer than a few meters
to her. The domain of her privacy we called her private space. As an original
name was being sought for the new component what better name than Brenda.
After all the connector allowed the user to enter
the ‘private space' of the original performance.

The design exercise for the BrendaTM
B1 not only drove me and my household a tad wacky but also met with comments
such as ‘impossible’ and ‘can't be done’ from two of the most advanced
machine shops in the country. Even the one where the engineer was
adamant that ‘we can do anything!’ also ran for cover. Fortunately he came
out again and a fabrication process was worked out. The final compromise
being that the centre pole piece had to be finished off by hand requiring
nearly 40 minutes per centre pole piece to hand finish it and assemble
the whole connector.
Brenda™
B2: "The Ultimate".
The design of the Brenda™ concept has lead
to several re-workings of the bare-wire design paradigm. The B1 Brenda™
has been superseded by the new design paradigm the B2: suffixed: "The Ultimate".
The Brenda™ B2 uses a locking cylinder to secure itself to the audio appliance
RCA chassis receptor.
The BrendaTM B2
has its wire insertion cylinders seamless to the transition interface when
gripping the RCA chassis socket. Every design aspect that can enable such
a connector to connect properly at this crucial transition interface has
been incorporated in the BrendaTM B2. The
signal piece is fully insulated from the earth ( negative ) assembly with
Teflon®. The colour coded polarity indicator doubles as wire clamp
and shields the insertion cylinders; it is fabricated from Delrin®.
The BrendaTM B2digs
deeper, delivers more detail and opens a wider more stable stereo holographic
stage / image than any other RCA type connector anywhere today.
The consequence is an RCA connector that has
extraordinary dynamics and enables the interconnecting cable to perform
at its maximum best.. Its dimensions are: 80 mm long x 38 mm diameter.
The Brenda™ B2 and B3 connectors
allow for the securing of an interconnect wire up to 4mm in diameter (
9/64" ) directly into the interconnect connector pole piece for both polarities
without the use of solder. There are no soldered pieces in the
Brenda™connector.

BrendaTM
B3: 'The Rocket'.
The BrendaTM
B3 is the standard production BrendaTM.
Whereas the BrendaTM B2 has the earth insertion
cylinder seamless to the RCA chassis receptor transition interface;
the BrendaTM B3 has the Earth insertion
cylinder coupled behind the Signal insertion cylinder. This enables
a smaller diameter BrendaTM
while still using a locking cylinder as with the BrendaTM
B2.
All other design aspects of the BrendaTM
B2
have been incorporated in the BrendaTM
B3.
The Brenda™ B3 is more adaptable for low profile
appliances where its size is more easily accommodated // and where
the RCA chassis receptors on the appliance where the BrendaTM
is being used, are at least at 19mm ( 3/4inch ) centers or greater.
The BrendaTM B3 has an overall diameter
of 17.7mm ( just over 11/16th inch ).
Its component parts are:
The Claw: this is where the BrendaTM
B3 clamps onto the chassis receptor.
The Signal Pin: This is where the Signal wire
( the positive pole ) is secured into its cylinder with twin grub-screws.
The Anchor: This is where the Earth and shield
wires are secured, also with twin grub-screws.
The ClawLockTM:
The ClawLockTM is almost as long as the
BrendaTM B3 itself. It screws back over
the Claw to secure the BrendaTM B3 onto
its chassis receptor. The ClawLockTM is
machined from solid Copper Billet ( no other locking interconnector
component anywhere in the world today has a Copper ClawLockTM
)
and acts as the perfect shield for the internals of the BrendaTM
B3.

BrendaTM
Design Features.
( Applies to the Bare Wire BrendaTM
)
-
All BrendaTMconnectors
are fabricated from HCOFC***
Copper, they are then electroplated with a minimum of 8 microns of Silver
and then electroplated with a minimum of 1.0 micron of Gold.
-
Insulation used to isolate the polarities within
the pole assembly is Teflon®.
-
The BrendaTM
B3
and BrendaTM
B2
connectors use a locking cylinder (
refer to Note 1 ) ( referred to as a ClawLockTM
) to secure itself to the operational appliances’ chassis receptor.
-
-
The (bare wire) BrendaTM connectors
will accommodate nearly all currently available interconnect wires without
destroying their fine crystalline ( single crystalline ) structure with
heat as happens at the time of soldering.
-
This allows the listener to totally benefit from
the advances made in materials in the last 10 years.
-
The BrendaTMinterconnect
connector component is available in sets of 4 allowing the end-user to
install whatever interconnect wire they wish to install.
-
The great advantage of the BrendaTM
connector is that even the cheapest interconnect cables, once inserted
into the BrendaTM connector, begin to outshine
cables costing twenty and even one hundred times the per meter price.
-
Enabling their owner to upgrade to the more expensive
cables when the budget allows and obtain sublime performance from them
not possible by any other means.
-
All ( bare wire ) Brenda'sTM
are unconditionally stable for phase and impedance at all audio frequencies.
-
What this means, is that audio imaging is
unrivaled and the most stable possible, their is no smearing due to solder
induced artefacts.
-
Standard electroplate for all Brenda's is a minimum
of 5.0+ microns of Silver and 1.0+ microns of pure Gold.
-
The Signal pins are electroplated with 3.0+ microns
of pure gold.

Brenda B11
'The Majestic'
Identical design
paradigm to the BrendaTM B2 the BrendaTM
B11 is a single piece RCA type connector. It has been designed to be able
to be used with those appliances that have their chassis RCA receptors
at half inch (12.7mm ) spacings ( which is the standard spacing on most
audio appliances ).
Unlike the BrendaTM
B2 'The Ultimate' the BrendaTM
B11 does not have a ‘ClawLockTM'.
It is a push fit connector.
Its dimensions are 61mm long x 21mm
high x 12.4mm wide.
Insertion cylinders for the earth signal (
negative and shield ) is 4.4 mm and for the signal wire ( positive ) is
4.0 mm diameter.
The BrendaTM
B11 is a bare wire unshielded RCA type connector.
The BrendaTM
B11 costs the same price as the B3.

Ambrosia
Ambrosia is a fully assembled interconnector assembly using the
Brenda B3 connector which has been electroplated with 15+ microns of silver
and 6 microns of pure gold. It uses rectangular section pure gold wire
for the signal and ultra pure silver for the return. I made a set of these,
on request, for an audiophile. After auditioning them I now offer them
as a standard fully made-up interconnector assembly.
Their performance takes audio to another level I never thought possible.
At first I noticed a level of detail and intimacy that surpassed the standard
Silver assemblies that I fabricate; but what impressed me most was the
degree of emotional involvement. After listening to Mahler's 4th symphony
with
Ambrosia I felt that I had entered
his soul at the time of its composition.
Ambrosia is as much a spiritual experience as it is a window on just
how excellent audio can be reproduced.

Using Brendas™.
-
The B2 is a big girl! To maximize the use of the
Brenda™ in your audio appliances the B3 is most apt ( and economical
) for low profile audio appliances and the B2 for those audio appliances
where the RCA chassis receptors are spaced more than 50mm apart ( as with
most power amplifiers ).
Where low profile audio appliances are being
used ( such as most pre-amplifiers today ) the bare wire BrendaTM
can be used in conjunction with the solderable
BrendaTM interconnectors. At the low
profile appliance end ( the pre-amplifier for instance ) the solderable
BrendaTM RCA connectors can be used.
At the Power amplifier end the interconnector can be terminated into bare
wire BrendaTM. The consequence is an unrivalled
quality of reproduction.
Many of the highend pre-amps such as the Audio
Research and Sonic Frontiers and Sound Reference models have the RCA chassis
receptors at distances greater than 19mm centres on the vertical. The current
BrendaTM B3 will easily fit these spacings.
Where care should be taken is where the RCA chassis receptors are attached
to a printed circuit board and 'poke' out of the audio appliance. In such
instances it is advisable to give the BrendaTM
some support so as not to dislodge the receptors from their mounting. Better
still fit TomCatsTM
and all these problems will disappear.
-
Where TomCatsTM
are used then careful spacing of the TomCatsTM
will allow the end user to utilize B2's throughout. For an All B2 installation
space TomCatsTM
at 45 - 50mm centres both vertically and horizontally. For an all B3 installation
spacing TomCatsTM at
20 - 25 mm centres both vertically and horizontally will allow ease of
access.
Performance.
-
Utilizing Brenda'sTM
with any interconnect wire will improve the performance available from
that wire. The bare wire Brenda'sTM
will allow any interconnect wire to perform at its maximum best. Musical
detail ( information ) is clearer and closer to the real event.
-
Your first impressions will be a sudden drop of
the noise floor Note 3
and a quantum improvement in emotional involvement with the the music.
-
The bare wire BrendaTM
connectors are very very fast; they are the fastest interconnector
on the market today!!!!!!
-
Transients and very low level detail are better
defined with a more accurate stereo holographic image and a Greater Dynamic
Range!
-
The electrical resistance of the components of
the Brenda™ connector are in the sub-micro-ohm range.
-
This is what makes Brenda™ very fast and neutral.
-
Your own front seat in the ‘private space' of
the original performance.
There are three domains of improvement as a consequence of using
Pure Copper Connectors.
Firstly
Due to the very high electrical conductivity ( in most instances
in the nano-ohm range ) the passage of the electrical signal is very fast.
The benefit ot this is that all transients are extremely fast and
with virtually zero colouration.
Secondly:
The very high electrical conductivity allows an enormous amount
of information to flow through.
Listening becomes more intimate and all spatial cues from the original
recording are better presented.
The listener goes from the flat '3D' so often mentioned by reviewers
to a full bloom.
Thirdly:
Dynamic range is extended to the maximum possible.
-
This is especially noticed in the bare wire RCA .
How to wire your interconnect wire into the grub-screw
engine in the B3 BrendaTM.
-
When inserting wire into the B3 BrendaTM
grub-screw engine trim the outer jacket of the cable back a distance of
'55 millimetres' at each end.
-
This will enable you to trim the individual insulation
jackets on each of the wire polarities easily.
-
Internally the BrendaTM
connector is quite long.
-
Trim 12 millimetres of insulation off the ends
of each polarity.
-
Fasten the rear most grub screw onto the inserted
cable while leaving the front grub screw hole empty.
-
I recommend that ROCOL
J166 Note4 be
inserted into the insertion cylinder via the front open grub screw
hole and then fasten the front grub screw into place.
-
Or that the stripped ends of the wires be smeared
with ROCOL J166; This may prove to be messy and the first suggestion
is recommended.
-
The Wire is secured by screwing down the
grub-screws securing it into the component.
-
Wipe away the excess ROCOL
J166.
-
Screw on the Claw-Lock and secure the cable jacket
with the securing locking screws at the rear and the BrendaTM
connector
is ready to use.
-
Sit back and enjoy!
-
Where very thin wires are used then use the outer
grub-screw to secure the insulated cable and the inner grub-screw to secure
the wire // and/or use some thin Copper or Silver shim inserted between
the base of the grub screws and the thin wires.
-
Do not over tighten the grub-screws onto the wire.
Adequate female firmness is sufficient.
OK serious audiophile: take a close look at your thousand dollar and
multi thousand dollar single ended interconnectors.
The RCA's on the ends are undoubtedly made from Brass ( some brasses
are made with high purity copper but they are still brass and have less
than 30% and nominally 23% the conductivity of pure copper )! And their
performance is of a brass connector!
I am still astonished as to how a manufacturer of an excellent cable
terminates the excellent copper or silver metals into resistors ( Brass
connectors ) at both ends!
What are you paying for!
Firstly an excellent crystalline metal conductor and then it is either
soldered or arc-welded into a piece of plated brass which has
a microscopically thin veneer of gold on a self magnetising thin Nickel
subplate! ( another thin film resistor! );
Secondly you are paying for a lot of marketing hype to get you to
part with your money for a well packaged dream: But in the end it's all
let down by the hopelessly cheap and useless RCA connector at the cable
ends.
Insist on having Brenda'sTM
on your audio investment and maximise the performance attainable from the
cable you buy.
The BrendaTM
is a precision Engineered component. Every aspect of its production is
totally controlled and manufactured to the
most exacting tolerances. No other RCA has had the attention of
excellent materials, design, manufacture, and assembly that the BrendaTM
has
had. And no other RCA can match the Brenda'sTM
performance.
