In case anyone may be interested, I received my Lavricable power cables. They underwent a 150-hour burn-in process prior to shipment. To get straight to the point , these are excellent and I'm very happy that I decided to give them a chance. I do not know exactly how power cables contribute to affecting sound quality, but they do.
I have been using Coincident power cables purchased new 13 years ago. They are very high quality 6N pure multi strand copper and shielded, very well made. They sound terrific in my audio system. Due to my success with silver IC/SC I became curious about silver power cords. The only way to solve that curiosity was to try some, so here I am.
Lavricable Grand power cables do not blow away the Coincident nor is there a "night and day" difference. The Grand cable is at this early stage as clear and transparent as the Coincident. But right away I noted distinctions between them.
The Grand is fuller and a bit warmer in tonality (Meat on the bone effect). Instruments has more body, weight and presence.
More reach out and touch tactility. They dig deeper into the nuance and subtleties of the music. They reveal more of the harmonics and intricacies of jazz guitar chords for example, More awareness of a drummer's brushes on cymbals and skin of the drums. Uncovering more of the growl of the tenor or baritone saxophone etc.
They provide more of an open 3-D space with increased apparent density of the individual performers. The thing is the Coincident did all of these various things quite well. The Grand takes this further. I love the combination of very high resolution with a very tactile natural sound. Not a hint of a clinical, sterile dry or analytical character, just very natural.
I'm very happy with what I'm hearing and will keep these silver unshielded cables. They have very similar impact as when I placed the Ocellia Silve Reference IC/SC in my system. Fuller bodied tone, increased harmonic overtones awareness and better exposure of the micro detail/nuances. I just have not encountered the thinness or brightness that others have complained about silver wire.
I do not know what accounts for my different outcomes but that's my listening experience thus far. @guakus thanks for starting this thread. I doubt that I would have come across Lavricables otherwise.
