Analysis Plus - Copper Solo Crystal Oval Interconnect & Power Cable

Using conventional round cable is like pouring fine wine through a lead pipe. What comes out is definitely not what went in. Copper Solo Crystal Oval interconnect is a crystal clear transmission path that puts nothing in the way of the musical signal. Our patented hollow oval geometry controls current bunching and frequency effects for the truest possible sound. Proprietary Teflon dielectrics resist energy storage, while premium Continuous Cast Copper braids produce the smoothest possible transmission medium.

Handcrafted Solo Crystal comes with your choice of locking RCA or Neutrik XLR connectors. Both configurations offer superior performance. Even the RCA-connector version takes advantage of a balanced configuration offering symmetry between signal and return, using 'hot' and 'cold' current paths along with a shield for an extremely quiet noise floor. You'll feel the Solo Crystal difference immediately, from the lump in your throat that tells you your music is alluring to the long-term assurance that your cable won't ever let you down.

Isolda Impedance Matched Loudspeaker Cable

Wherever electronic signals are transmitted by wire, be it telephone, video, digital data, radio or TV, the impedance (NOT resistance) of the interconnecting cable is ALWAYS matched to either the source or the load, to prevent distortion. In the case of hi-fi about the most important link of all is the speaker cable – and it is here that this rule is completely ignored. The result is a grossly mismatched connection, with the mismatch being typically twenty-to-one as most speakers have a nominal impedance of about eight ohms and typical cables a characteristic impedance between 100 ohms and 400 ohms. No wonder speaker cables sound wrong! Townshend Audio Isolda Impedance Matched Loudspeaker Cable, which has a characteristic impedance of eight ohms, remedies this. To achieve an impedance match at such low impedance values the cable must exhibit very low inductance and high capacitance. It is well known that high capacitance can upset some amplifiers, which become unstable. To counteract this, a correctly engineered, inaudible inductor, in parallel with a damping resistor, is inserted in series with each leg of the cable, at the amplifier end, for assured stability.

The two inductors also act as a filter to prevent radio frequency interference (RFI), present in abundance at the end of the cable, from passing to the circuitry of the amplifier. Further, the very close spacing of the conductors in the cable provides a further level of RF rejection. The result is black silence. What happens when the impedance between the cable and the speaker is closely matched? The answer, MAGIC! The sound is fast but not bright; it is clear, open, fatigue-free and grain-free. Bass notes are precisely defined, deep and tuneful, with amazing impact. The midband, especially female vocals and solo instruments, takes on a naturalness never before heard from reproduced sound. The treble is smooth and fast with both brilliance and sparkle. But the cables never sound bright, brittle, grainy or spitty. They just sound ‘right’.

ISOLDA DEEP CRYOGENIC (DCT) INTERCONNECT

All audio cables are adversely affected by the insulating material (‘dielectric’) in which they are sheathed to prevent short circuits. The best insulator of all for an audio cable is a vacuum, but of course this is impractical. Next best is air, followed by PTFE, polyester and polyethylene. PVC, the most widely used cable covering, is one of the worst performing dielectric materials. To reduce the influence of the dielectric to a bare minimum, Isolda Deep Cryogenic Interconnect Cable uses a novel form of construction in which 3x0.1mm copper strip conductors are threaded through 3mm internal diameter PTFE tubing.

Because the copper strip only touches the inside of the tube along its edges, the effective dielectric is about 95 per cent air, 5 per cent PTFE – a major improvement over conventional cable construction where the insulation is moulded around the conductor. Two of these threaded tubes are laid side by side and then enclosed in a tough polyester braid to form the complete cable. Use of a flat strip conductor minimises series inductance, while the wide spacing of the conductors minimises shunt capacitance. So the cable imposes negligible filtering on the audio signal, whatever the output impedance of the signal source. As a result of this thoughtful construction, Isolda Interconnect has a uniquely ‘hear through’ sound quality, devoid of the fuzziness, tonal imbalances and graininess which afflict other interconnect cables. But we’ve now found a way of making it even better.
