Descrizione

Coppia Cavi di Interconnessione stereo phono-phono che utilizza due conduttori di diametro diverso per fornire un percorso alternativo ai segnali delle alte frequenze, nuova guaina in PVC che assorbe i disturbi delle alte frequenze, nuovo connettore QED ANALOC™ dorato 

Lunghezza Disponibile: 1 metro. Tutte le altre misure su richiesta


IL RIVOLUZIONARIO CAVI DI INTERCONNESSIONE AUDIO ANALOGICA REFERENCE AUDIO 40 CELEBRA I 40 ANNI DI QED NELL'AVANGUARDIA NEI CAVI AUDIO INGLESI 

La gamma di Cavi Audio 40 è un nuovo concetto di design dei laboratori QED. Tra le corde è progettato principalmente per bassa capacità come è stato identificato da QED come un fattore significativo che porta ad una elevata esperienza di fedeltà, rendendo per un suono compatto e mantenere il ritmo del pezzo originale. Aggiungi il nostro complementare Direttore TechnologyTM per alta dettagli frequenza e la nostra Analoc TechnologyTM per massimizzare l'integrità del segnale e il risultato è ciò che sentiamo essere la interconnessione più innovativo mai realizzato da QED.

"Build quality and feel are very reassuring - you're immediately drawn to the smart looking 'Analoc' locking plugs."

Like most interconnects here, the Reference Audio 40 is a silver-plated copper affair, arranged in a special complementary way – the two conductors have different diameters, and this is said to give an alternative path for high-frequency audio signals to avoid time smear. The foamed polyethylene dielectric is claimed to reduce the amount of signal lost to cable capacitance. QED’s Analoc plugs are fitted, said to be a low eddy current design with copper instead of brass used. They feature an outer locking cylinder that needs to be screwed forward before the plug’s ‘blades’ can be locked onto the RCA phono socket, then the locking cylinder needs to tightened backup for a (very) secure fit. The Signature Revelation speaker cable uses 10 silver-plated oxygen- free copper central conductors, which are claimed to provide very low resistance alongside high levels of detail. These cores are separately insulated and arranged around a hollow core of polyethylene; QED calls this its Aircore technology and it’s claimed to reduce inductance.

 

Sound Quality

Before the QED loom, the panellists have taken a mixed view of the various wires played to them. They’ve found positives and negatives, liked some and been lukewarm about others. But two out of the three listeners express a strong preference for this set of cables, applauding it for its clean, open, even sound that doesn’t try to do anything too clever. Instead it is very accomplished at almost every facet of the music, and makes things look rather easy.

 

 

   

“Everything is joined up,” says one panellist, and so it proves. The Lorde track plays better than it has through most others here. Although not necessarily the warmest or most expansive, it just seems to gel the bass with the rest of the music – which is something several others fail to do.It doesn’t sound too steely in the midband, giving a nice smooth sound to female vocals, and treble is crisp and finessed. Musically the loom works very well, the beat bouncing along in an enjoyable way. The result is a surprisingly easy listen, when previously the track hasn’t quite made sense.The REM tune is described as sounding, “head and shoulders better” by one panellist. There is a fine sense of depth to what can sound a pretty close and claustrophobic mix. One can hear lots of detail too, with the keyboard backing track coming through from the second verse, where previously it had been submerged. Tonally the QED isn’t the warmest or most sumptuous here, but it is very even and transparent and doesn’t seem to be trying to add or subtract anything much. This means that it’s likely to work well with a wide range of systems. Moving to the Duke Ellington piece and the pattern continues. One adoring panellist describes it as, “good bass rhythm and control, nice, cohesive, great sound, head and shoulders better”.Another of the panellists isn’t quite so enamoured; they appear to yearn for the expansive yet sumptuous midband of the Ecosse, and find the QED a little too anodyne and bland when playing Julian Lloyd Webber’s cello work. All of which just goes to show how much taste plays a part, but still this remains a superb result considering its low price

 

 

 

 

FEATURES AND BENEFITS

COMPLEMENTARY CONDUCTOR TECHNOLOGYTM

This innovation utilises two conductors of different diameters to carry the same audio signal. This has the effect of providing an alternative path for high frequency audio components which might otherwise become time smeared in a single audio pathway.

 

FOAMED POLYETHYLENE DIELECTRIC

Foamed Polyethylene has a low dielectric constant and has been used to cut down on the amount of audio signal energy lost due to cable capacitance.

 

ANALOCTM LOCKING RCA PLUGS

The new QED Analoc™ plug is a low eddy current design featuring small high purity copper

conductors in place of the usual large volume brass body found in ordinary high quality plugs. This cuts down or eliminates the tendency for the changing magnetic field in the conductor to induce eddy currents which can affect the micro-timing of the audio signal.

 

SPECIFICATIONS

Silver Plated 99.999% Oxygen Free Copper (SPOFC) conductors with LDPE dielectric
Asymmetrical twisted pair geometry

OFC shield giving 100% electromagnetic screening

Zn/Mn ferrite Jacket

Gold plated QED ‘Analoc™’ RCA plugs


Parallel Capacitance: 76 pF/m

Inductance: 0.37 uH/m

Loop resistance: 0.072 Ω/m

Dissipation Factor: 0.0059

 

QED Lifetime Guarantee

 

 


Reference and Signature Audio40 analogue cables use ‘Analoc™’ plugs with a built-in locking feature so that as the barrel is screwed up tight, the clamping force is increased making for a super noise free and secure connection.

 

 




To correctly fit ‘Analoc™’ plugs, the outer locking cylinder of the plug must be screwed forward, to loosen the gripping ‘blades’, whilst the plug is pushed into place on the socket. The locking cylinder should then be screwed back in order to lock the plug onto the socket. Needless to say, users must always remember to do this when connecting/disconnecting the cables.

CABLES MATTER

There are three cables in the Audio 40 range representing the long established Performance, Reference and Signature designations which have always corresponded to the “good, better, best” principle of QED product hierarchy.* However the whole range has been developed using a strict top down approach which means that all three cables share an almost identical construction and geometry with the Signature cable representing the ideal ‘cost no object’ original state of the design with the Performance cable its cost engineered alternative. The Reference cable represents the perfect balance of performance against the law of diminishing returns omitting only the most expensive components.

The cordage is designed primarily for low capacitance as this has been identified by QED as the primary factor which leads to a hi-fidelity experience and makes for a tight sound which retains the rhythm of the original piece. Further unique steps have also been taken to eliminate minute timing errors in the cable. Our new complementary conductor geometry is used throughout the range and utilises two conductors of different diameters to carry the same audio signal. This has the effect of providing an alternative path for high frequency audio components which might otherwise become time smeared in a single audio pathway. Another innovation added to the entire range is the specially impregnated PVC jacket containing 10% Zn/Mn ferrite material. This absorbs very high frequency noise signals and audio signal components which are thought to have an adverse affect on the micro-timing of the audio signal. Low dielectric constant materials such as foamed polyethylene or teflon have been used throughout the range to cut down on the amount of audio signal energy lost due to cable capacitance and all of these measures have been applied under the consultation of leading industry experts. We have been able to measure the affects of these improvements using our high frequency cable test suite.

 

Additionally the new locking plug does nothing to spoil the low jitter, low noise signal provided by the cordage. The new QED Analoc™ plug is a low eddy current desi
