Ecosse La Prima Donna Interconnects

An Audiophile-Reference Grade cable La Prima Donna Analog Interconnect superdeeds the previously-named Myth Interconnect, and compliments the performance of high-end single-ended hardware, irrespective of price.
La Prima Donna DiagramLa Prima Donna is stunning designed and beautifully constructed. Indeed, every inch of this cable has been well conceived and precisely executed. The conductor and return, the interior insulation, the triple screens, the vibration control, and the outer jacket, have all been designed as one. 
So what so unusual about La Prima Donna: well in this age of ultra expensive, over hyped interconnects La Prima Donna is unique. Firstly its NOT made of single crystal copper*.

Secondly, although its ‘asymmetrical’, it is also available in balanced configuration. Here the centre core is positive phase, the inner screen negative and the outer screen becomes ‘earth’...

Thirdly and most importantly its conductor is ultra high grade SOLID SILVER OF 6N purity. (99.99997%), perfectly circular in cross section and offering stunning propagation speeds. The return conductor is a close-lapped braid of heavy silver-plated Ultra-Hi Purity-OFC™ (grounded at source end only). This is sheathed in an expansive (and expensive) PTFE (Teflon) separator. A copper foil and tertiary outer screen of silver-plated Ultra-Hi Purity-OFC™ ensure 100% coverage against the deleterious effect of RFI, EMI, and ESI induced distortions.

Fourthly, and heres the clever bit, there is a layer of Neoprene ‘Vibrakill™ sandwiched between the outer screen and the soft PVC jacket, virtually eliminating the effects of microphony and contributing greatly to the preservation of the accuracy and integrity of the signal.

We offer La Prima Donna Analog with our most sophisticated RCA plug assembly-the awesome MACH3 constant-impedance Monocrystal™ Ag (silver) over Cu (copper) RCA plugs with their unique self-cleaning conjugate bracket shields (designed to form a ‘Faraday Cage’-a device designed to maximise RF screening). A heavy, silver-plated brass body, with twin high tensile fixing screws, clamps this double-shielded assembly uniformly and without stress. This shield, which grips the cable, does so firmly but without compressing the cable, ensuring that the crucial characteristic impedance is maintained. In ‘balanced’ configuration we use our over-designed MACH3 Ultima XLR plugs.

For lovers of music where cost is an object- La Prima Donna must be on your list.

It is sincerely recommended that you consider matching 'La Prima Donna' with either our SMS2.4 loudSpeaker cable or, for ultimate satisfaction, with our US2 Monocrystal™ Silver Speaker Cable. The complete cable-matching table is here.

*An audiophile conductor material that Ecosse pioneered back in 1996 and brought to the market at prices audiophiles could afford. Monocrystal™ single crystal copper and silver is Ecosse‘s unique Trademark.

A word about our unique terminations
The terminations at the ends of cables are part of the transmission path and therefore vital to it. They must not impede the delicate audio signal as inappropriate termination changes the so called characteristic impedence (and other electrical attributes) of the cable. The can be severely compromised by poor, compressing RCA plugs that grip the cable with a grub screw or a collett action. The cable loses its integrity and the impedance can drop to somewhere in the region of 35 Ohms resulting in reflections and a deletions.

To maintain the quality of the all-important interface between interconnect and component, and compatibility between wire material and plug, Ecosse has developed our unique and ULTIMATE non-compressing constant impedance MACH3Ag ULTIMA RCA plug. This high quality RCA plug consists of a centre pin and conjugate bracket shield* which together offer going and return paths for the audio signal.

For continuity and optimum conductivity, these contact points are made from direct hard silver plated Monocrystal™ copper(others use 'flash-gold' OFC plating which is a very thin coating that wears away very quickly and soon looks tarnished!). The plug casing is precision machined from highest quality copper alloy and is deep-plated. This thick casing offers further shielding - effectively a second 'Faraday Cage' - and reduces the ingress and radiation of EMI, ESI and RFI 'noise' even further, to virtually zero.

The interface of shield and casing is one of high mechanical impedance, dissipating energy and rendering microphonic effects negligible. The full assembly represents Ecosse's Audiophile Grade RCA termination for smaller diameter cables and we believe the Ecosse MACH3Ag ULTIMA RCA to be the best available price wise, electrically, mechanically and aesthetically - anywhere!

These shells are designed to perform a 5-fold function:

They provide a terminal to which the return/screen conductors can be firmly crimped and soldered.
They incorporate tiny teeth that grip the cable firmly and evenly around its circumference without compressing the cable and thereby maintain the cable's characteristic impedance right up to the solder joint.
When assembled, they form a Faraday cage, screening the signal right up to and including the RCA socket.
They form a union of high mechanical impedance with the outer casing, dissipating energy and therefore rendering the plug immune to the effects of microphony.
They firmly locate and clamp the centre pin's polypropylene dielectric, which, in conjunction with the outer casing, results in a strong, stable and extremely durable structure.
