Blue Truth® ULTRA XLR Cable Overview

Years in the making and our first upgraded XLR Interconnect design in over 10 years. The wait was worth it! The Blue Truth ULTRA XLR interconnect builds on the success of our hugely popular and well-reviewed Blue Truth XLR interconnects. The Blue Truth ULTRA XLR cables are a substantial step up in performance. We changed from a stranded-core to a solid-core silver-coated copper conductor. We also upgraded our dielectric material to a fantastic foamed Teflon® insulation.

How does this change in construction affect the sound? You will get amazing clarity and detail. You will get an improved soundstage. The voices and instruments sound more realistic. There is no harshness in the sound and you will experience no listener fatigue. EVERYTHING IS BETTER!

This balanced audio cable is a dual conductor, twisted pair configuration. It features SOLID CORE 99.999% pure silver-coated copper conductors. Plus an equally pure silver-coated shield will put you in sonic heaven. Balanced lines are the preferred method (for hum-free) interconnecting of sound systems using a shielded twisted pair. The principle behind balanced lines is that the signal is transmitted over one wire and received back on another wire. The shield does not carry any information, thus it is free to function as a true shield. This circuit's shining virtue is its great common-mode noise rejection ability. The concept here relies on induced noise showing up equally (or common) on each wire. It is mainly due to EMI (electromagnetic interference: passing through or near magnetic fields), RFI (radio frequency interference: strong broadcast signals), noisy ground references, or a combination of all three.

Our Blue Truth® ULTRA XLR cables exhibit exactly equal impedance from each line relative to the ground, guaranteeing equal noise susceptibility. Since the balanced input stage amplifies only the difference between the lines, it rejects everything else (noise) that is common to the lines.
Silver is the conductivity KING when It comes to audio cables. Gold is good, copper is great, but silver is the best! Blue Truth ULTRA XLRs contain silver in the conductor. Silver, a precious metal, is the ONLY metal with a higher electrical conductivity than copper. Blue Truth ULTRA XLR Interconnects use 99.999% pure silver. The electrical conductivity of silver is 106% of that of annealed copper on the IACS scale. Even though the cost of silver is much greater than copper, its sonic benefits are immediately apparent. We also use ultra-pure copper in our Blue Truth ULTRA XLR Interconnects. The addition of copper brings “warmth” to the audio sound-complementing the sonic detail from the silver. The Blue Truth ULTRA XLR Interconnects strike a unique balance between outstanding performance and cost.

Blue Truth® ULTRA XLR Audio Cable Technical Information

Solid-core silver-coated conductors.
100% coverage shield.
Features audiophile-grade Neutrik Male to Female XLR connectors with silver contacts.
Extremely low 12pF/ft capacitance.
Foamed FEP Teflon® dielectric insulation.
110 Ohm Impedance - perfect for digital AES/EBU.

The hybrid construction gives all of the sonic benefits of silver (dynamic high frequencies) and all of the sonic benefits of copper (deep, tight bass response).

…But what both Blue Truth cables offer is a glimpse into a much bigger world of high-end cable design, with both the XLR and USB punching above their respective weight classes.
Alan Sircom (HiFi+ Magazine - Blue Truth ULTRA XLR Cable review)

The Blue Truth® is their latest iteration of simplicity, quality, and not very expensive...Teflon is the dielectric, which is considered the best there is, with its low dielectric constant, and should provide a low capacitance. The sound quality was solid, and what I have come to expect from BetterCables. There was no harshness or smearing that I could detect. All in all, these latest BetterCables® products are as listenable as any that I have heard.
John E. Johnson, Jr. - (Secrets of Home Theater & High Fidelity)

This combination of silver, low-attenuation, and high-quality Teflon® insulation makes this a world-class balanced audio cable.
