Argenti Ultra Loudspeaker Cable
Argenti Ultra Loudspeaker Cable Cables Description Robson Acoustics have been listening and appraising loudspeaker cable for many years now for both the internal wiring of speakers to dedicated loudspeaker cables in order for our range of speakers to sound at their optimum. We often sell cable which is identical to the internal wiring of our speakers to perfectly match the signal path where often in floor standing speakers the length of cable within the cabinet can be as long as a set of external cables. For this reason alone our dedication to finding the best cable is of the utmost importance and why Argenti was developed to provide a balance between Ultra and our new Reference speaker cable. Argenti speaker cable is made from directional and ultra pure copper which has the ability to reduce the “grain” in vocals and higher frequencies, tighten bass and give a “blacker” background to the music. Engineered to exacting standards, deep cryogenically treated and conditioned using our in house cable cooker which eliminates the dreaded long burn in process associated with cables especially loudspeaker and power cables. Exceptional in terms of incredible micro dynamic resolution, soundstage and to impart as little distortion as possible. This is a very smooth sounding cable with no loss of detail.

Argenti Reference Interconnect Cable
Argenti Reference Interconnect Cable Cables Description Our all new Argenti Reference interconnect cables employ a standard of silver rarely seen anywhere else with a true 5N purity (99.999 purity) silver wire with 4 layers of natural bleached cotton wrapped around a porous Fluoropolymer tube. The extremely high standards around which the pure silver wire is drawn results in lower crystal structure damage and surface marring. As always, the dielectric is extremely important. This cable uses a unique blend of 4 layers of natural unbleached cotton where the surface of the silver wire makes minimal contact with the individual fibres of the cotton resulting in a very low dielectric constant. Cotton also has very good properties in relation to dampening and non resonant behaviour. Both wires are then wrapped around a tube made from porous Fluoropolymer which also has low specific gravity and a very low dielectric constant of less than 1.3. This is much lower than PTFE which is around 2.1 The very best Viborg solid silver RCA or XLR plugs are used in both the unbalanced and balanced cables. After many hours of construction the whole cable is sent off for deep cryogenic treatment followed by cable conditioning on our in house Audiodharma cable cooker. The cable still requires a minimum run in period to settle into any given system and is now directional. Reference interconnect features : Pure silver 0.99999 5N solid core wire 5 layers of natural unbleached cotton dialectric Porous Fluoropolymer tubing for inner core 2.5 day cable conditioned Deep cryogenic treatment Pure solid silver RCA/XLR plugs For our own demonstration suites and systems, this cable has replaced a well known brand costing nearly £4000 with added holographic presentation and dimensionality.

Burlington
Burlington MK II Speakers Description The new Burlington Mkll has taken many years to develop and a big achievement to supersede an already very popular design. Based around a cabinet of high structural integrity using constrained layer damping philosophies in much of it’s design and using possibly the best bass/midrange and tweeter on the planet with a cross-over that flawlessly integrates both drivers together. As with all new designs we are constantly trying to raise the bar in terms of simple musical enjoyment where you can connect with the music being played. The Burlington Mkll does this in a truly holographic nature! Stereo separation and the natural decay of notes are portrayed in exquisite detail and resolution. High frequencies such as cybils and the natural air and textures around instruments give an astounding realism to recordings especially live venues. Although this design incorporates a single Purifi Audio 6.5″ Ushini driver for bass and mid frequencies, the level and quality of bass produced still amazes everyone. Capable of reproducing the lower octaves of music with extreme speed and authority. Special attention was given to the cross-over design which uses specific components to match the drivers irrespective of cost. Additional damping applied to the cross-over board with point to point wiring, silver solder and internal wiring using 99.999% 5N OCC copper wire with Airlock insulation made from fluoropolymers. Each base is made of 10mm steel with isolation coming from our Panzerholtz and ball bearing feet which has been proven to give a far superior isolation of loudspeaker to floor. It is essential to dampen the vibrations emitted by loudspeakers either through the air or via the ground borne vibrations with both equipment dampening and loudspeaker dampening techniques. Spikes and “soft” isolation feet generally do not work and can introduce various problems when connected to differing floor structures. Both the stand mount version and the floor standing model will redefine the possibities from an audiophiles perspective in terms of sound staging, resolution and dynamic contrast. Vanishingly low distortion figures are only 1 of many features these loudspeakers exhibit bringing the listener closer to the ” in real life” musical experience within your listening space than ever before.
