Returning to today’s cable topic, Richard Cesari—who as you will have understood is very creative—considers cables to be passive components which regardless of brand or price can only incur signal losses. His approach to cable design is thus articulated for two goals. On one hand, he must reduce these losses for maximum data retention across the audible range. On the other hand, he must avoid signal alterations. He thus takes great care to do no harm, including paying attention to proper phase response.


As a result of this view, Richard Cesari early on determined the main cornerstones for Esprit Cables. These consist of a balanced scheme of high-quality long-grain copper conductors. Cesari works with rather large conductor surfaces and unbalanced dielectric geometries. Much care is devoted to his own pure copper connectors with thick silver plate of almost 40 microns to avoid the usual shortcomings of eddy currents, capacitive reactance and micro arcing when silver is applied too thinly. He views this as today’s best option for high conductivity. Cesari also considers mechanical damping of all cable constituents important (conductors, shield, insulation, connectors) and believes its impact to be significant to the final result. On the shielding front, Esprit cables get highly protective shields and since the Eterna range, Cesari adds a further polarisation system to reinforce it.


Over the past 15 years, his catalogue has grown over eight generation into its current range of 9 families. The Linea range is a simple oxygen-free Teflon-shielded copper wire. Then comes the Alpha range with pure copper conductors, 40 micron silver-plated connectors and stronger shielding. The following Beta series is the topic of today to be discussed later. The Kappa range uses an asymmetrical dielectric on an air layer with partial screening and a 720-strand pure copper conductor. The Celesta line introduces balanced interconnects not available in the lower ranges and 1’120-strand pure copper conductors for each speaker cable. The Eterna range introduces a battery pack which puts the cable’s dielectric into a comparatively high-voltage field of DC. Its speaker wires are made of 1’680 pure copper strands whilst interconnects run 810-strand conductors.


Aura wires add a complex air/glass layer partial shield. Lumina interconnects increase the number of pure copper strands to 1’230, Lumina speaker wires hit 6’600 strands of long crystal copper. Last but not least, the Gaia flagship features 1’600 strands for interconnects and a progressive twin shield over air with integral optical sleeve. In addition, insulation, mechanical damping and the battery supply are strongly enhanced to provide top achievable performance from this approach. Though not as deep as the AudioQuest catalogue, Esprit’s lineup is surprisingly deep for a single-operator outfit. To complete Cesari’s mini profile, let’s announce that for 2015 he should return with new products under the brand Esprit High End Audio, with a two-way loudspeaker based on an Accuton/Peerless driver mix with twin bass reflex loading.


Description. My Esprit cable loaners arrived in nice protective black cases. The care given to their overall presentation and packaging really suggested a higher than actual sell price. The Beta interconnects are a symmetric design within an asymmetrical dielectric. They look rather pretty and their build quality is among the very best in this price range I’ve encountered. The conductors consists of 650 strands of pure long-grain copper. Richard Cesari applies progressive shielding with full optical sheets and mechanical damping.
