The sound of no cable

ArgentPur started as a minimalist assault on the requirements of audio signal transmission.

Pure silver (Ag) has a 106% conductivity compared to the maximum theoretical transmission of copper at a technically defined 100%. So even umpteen-nines Cu can't remotely approach pure silver. The market is flooded with silver plated copper conductors. To many, these have compromised qualities that limit top octave clarity, coherence, and may lead some to describe them as "bright," "etched," or having "glare". Pure silver has no such compromises, and indeed has NO SOUND of its own.

In order of preference, the available media for the Ag conductors to rest within are: a vacuum (rather impractical), air, and then the low dielectric effect insulative barriers when necessary. The best of these are arguably the fluorocarbons.

To minimize dielectric effect further, each individual  Ag strand used in ArgentPur is manually threaded through its own fluorocarbon tube that is 5-10x larger so that contact between the Ag conductor strand and its protective carrier is dramatically reduced by this roomy air space. Capacitance and inductance are thus minimized, with the benefit of no "signal-hopping" destructive interference across the frequency spectra. (See Core Technologies below.)

Premium WBT0152Ag are used to terminate the Athene and Heracles RCA designs.  A wonderful Ag/Teflon XLR is used for the balanced designs, with locking silver Neutriks available for pro use.

Speaker cables are terminated in very burly Ag-plated spades and Ag-plated banana plugs for complete continuity of Ag conductance.

NO lower-conductivity rhodium, gold, nickel, nor copper surfaces are in the signal paths! Only 105.9995% transmission pure Ag!

NO other hefty cheap "fillers" like PE or PVC are used to add unnecessary weight nor girth in marketing ruses to enhance gravitas. Pure Ag cascading through air-filled Teflon to Ag-tipped connectors!

NO performance claims are made differentiating among the AgPur Speaker Cable iterations, as load sensitivity and length requirements should guide Ag AWG mass selection among the four models. How refreshing!

NO CABLE! The sound and raison d'etre for ArgentPur!

Core technologies

Cable Geometry

ArgentPur's solid Ag strand cores are initially arranged as twisted pairs, followed by aggregation of spirals and star-quads to lower mutual inductance and capacitance. The final exterior geometry of these groups consists of twisted pairs (AGPur Speaker) or tri-braids (Interconnects). AgPur single-ended (RCA) ICs follow this noise-cancelling tri-braid external geometry to reduce noise in an unshielded design, which results in a purer musical performance than shielded constructions. Remote outer shields may be added for especially noisy environments by the end user, only as absolutely necessary.

Connectors – All Silver-plated

Speakers Terminations include very robust, twin-screw, Ag-plated variable-orifice spades, as well as appropriate high-friction compact or looser extra-large bananas. Standard construction of AgPur Cables incorporates BOTH spades and bananas. Interconnects 1. XLR Harmonie is terminated with Neutrik Pro Ag locking connectors. Athène and Heracles use an Ag-plated fluorocarbon dielectric premium XLR. Locking Neutriks are a no-cost substitution for pro or studio use. 2. RCA Single-ended AgPUR interconnecting cables use a minimal mass RCA plug made of silver-plated tellurium/copper contacts. This design preserves an all Ag conductor path, providing total signal coherence. Alternatively, locking WBT 0152Ag are used, especially for Pro or studio use.

Interconnect Conductor Mass

Unlike many other “pure” silver interconnects that only offer 19-24AWG total conductor mass, thus possibly reducing signal current, silver mass in AGPur starts at 19 AWG in its Harmonie model, increasing to 18 AWG in the higher resolution Athène, culminating in an unheard of 16 AWG in the peerless Heracles, providing extremely low series resistance and huge bass slam!

Solid Ag Strands

AgPur’s cable cores consist of arrays of variable strands, arranged in accordance with the Golden Mean ratio. Each hand-polished silver strand sits in its own voluminous air-cushion within a fluorocarbon barrier to provide vanishingly low dielectric interference. This purely holistic strand arrangement ensures optimal performance by also eliminating cross-strand effects whilst ensuring low capacitance. AgPur thus provides a complete 100% silver pathway, using only roomy Teflon ”air-tubes” as physical barriers. No PVC, PE, other plastics, textiles or foams are used!

Variable Strands

Multiple pairs of solid Ag strands, scaled by the Golden Ratio (1.168), combine to provide a naturally balanced musical portrayal through all octaves... with unmatched air, top octave resolution, and exquisitely detailed stage imagery.

"There is something extraordinary going on here and amazingly beautiful... Could it be magic?"

"I'd say it's the only silver (cable) that outranks the most expensive all-copper I have ever heard!"

"...sounding as good as anything on the market.... I still can't believe it is so.... Your pricing for the gauge that I have (AgPur12, $6k 2.5M) is quite amazing compared to other high end companies! It is perfect with a smooth ambient effect and much detail and huge soundstaging. Nothing ever SHOUTS AT YOU...they are that musical!!"

— Howard Milstein, The Sound Advocate

Interconnects

ArgentPur offers three tiers of Interconnects, available both single ended (RCA) and balanced (XLR).

HARMONIE

ArgentPur Harmonie comprise 19AWG (0.65mm2) Ag in a simple twisted-pair geometry finished as a tri-braid. It is evenly balanced, affordable, with fine clarity, staging, and octave-to-octave coherence.

"To say that I am impressed is an understatement. The organic wholeness, the octave to octave balance, and the detailed yet extremely smooth top end was fantastic."

"...the RCA cables: So far, so great! Nice bass extension couples with a huge soundstage."

"Uncolored, unfiltered, highly revealing of source material and room treatments."

Flyovers

AgPur226 Flyovers provide a very affordable taste of the finest twisted pairs of solid, pure Ag used in all ArgentPur formulations, conveniently terminated in bananas. When overlaid onto existing high-performance cables (especially all-copper), they usually add soundstage air and detail to an already acceptable presentation...especially with reference-level components upstream and superlative software files and/or superb vinyl. Note that Flyovers are not band-aids for systemic flaws, nor tone controls that eliminate existing problems in the treble octaves due to silver-plated conductors, low-res files or lesser tweeters, for example. Achieving a completely holistic musical presentation across all octaves is then achieved with a complete AgPur Speaker Cable as the next magical step. Flyovers offer a taste of pure silver frosting before eating the cake!

"...they're a phenomenal duo. Better than TQS (TelleriumQ Statement) by some distance...not a subtle thing... a massive difference."

"The Heracles (RCA) explodes out into the room and hangs in the air around you....(they) are in another league."

"...on the analogue (vinyl) they sounded like master tape."

"...easiest A/B test (with TQS) I've ever done. These are far and away transcendentally better than anything I've ever heard."

"These reset the yardstick, and do so with a knowing smirk and a wink...they're masterful."

— Conrad Fulbrook, MA RISD, early adopter and website design

"These are very very good. I'm going to wire my three rooms at Capfest with them."

— Jose Ramirez, DR VINYL

"They made my (baby) Spendors (with big Hegel integrated) explosive! You can have your subwoofer back...."
