The Heimdall 2 Digital coaxial interconnect cable also incorporates the standard Norse 2 features (i.e. Micro Mono-Filament FEP Construction & solid-core, 99.99999% OFC with 60 m silver-plat- ing) with the following specifications: 20 AWG, 75 Ohm impendence and signal propagation of 88% the speed of light. Connectors are high-quality gold-plated Neutrik BNC/RCA.
I inserted the 1.5m Heimdall 2 Digital interconnect between my Squeezebox Touch player and ADL Esprit DAC. Replacing my DH Labs cable with the Heimdall 2 resulted in additional warmth and smoothness. The treble no longer seemed highlighted, while losing nothing in extension and detail. The flow of the music was enhanced, providing more genuineness. Shelby’s voice too gained a share of this warmth and smoothness but also sounded more dimensional, more embodied. I was also able to perceive more texture and harmonic rightness in the brassy sound of the hi-hat and cymbals and their decay was now further drawn-out. Overall, the presentation was more relaxed, largely due to an absence of hardness, exaggerated sibilance or highlighting. In fact, I’ve heard less of an overall increase in performance when I’ve tried DAC’s of twice the price of the ADL Esprit in my system.
The Heimdall 2 analog interconnects incorporate the standard Norse 2 features and have the following specifications: 4 x 24 AWG, capacitance of 25pF/ft/ch, impendence of 0.06 H/ft/ch, and propagation delay of 85% the speed of light. Terminations are Neutrik XLR, Din or Nordost’s own proprietary MonnGlo RCA connectors, which I found to be sturdy and secure.
I first introduced the analog interconnects between the sources and the preamplifier, leaving the Kimber Hero RCA cable in place between the preamplifier and amplifier. The first thing I noticed was a deeper soundstage – there was added clarity but also a greater sense of ease. The hihat now took on a very life-like presence with added detail and now Shelby’s voice was entrancingly real – more resolved and more focused. Bass guitar was more extended with another level of tightness and agility that brought across its texture in a new manner – now, not only was the vibration of the strings easily audible at the pluck but lucidly throughout the entire note, pluck to pluck. I found myself thinking – this is no longer hearing, this is feeling the music! Another surprise was the effect this latest change had on my awareness of my own quadral Aurum Montan VIII loudspeakers, within my room. Now, with the analog interconnects in place, they had become imperceptible but so had the presence of my own room. This is not to say that I didn’t have great soundstaging before but now, in comparison, it was on another level. Next, I added the Nordost XLR analog interconnects between the Simaudio preamp and my Bryston amplifier. As a result, there was an added delicacy and clarity to the treble, greater bass control in the lowest regions and a heighted sense of overall liquidity
