Hello Pierre,
I received the package in perfect condition.
I couldn't resist comparing the original Kennerton cable with your Vectura C.
First of all, the workmanship is just as meticulous as the packaging, thank you. The comfort of this flexible cable is truly superb, which is already a big plus.
But where I'm particularly pleased with my purchase (and therefore with your work) is, of course, the sound !
This is also where the Fostex HPA8-mk2 is so useful to me : I can compare the two cables in three seconds on the same track.
Perhaps "spectacular" would be a bit of an exaggeration, but the improvement is very, very noticeable : slightly higher gain, mor mechanisms, percussion, keys, frets, and breaths.
I sometimes felt that the original wired headphones had to "choose" between two frequency "stages" when mids and bass coincided, a sort of acoustic "pump" effect that pushed certain low frequencies to the forefront, slightly masking higher frequencies (typically, a double bass could very slightly overpower the room's ambiance, applause, or even the performer's voice), potentially causing fatigue. This is no longer the case; there is no longer any competition, but true harmony, a soothing smoothness, gradual progression, and precision. It's no longer the headphones that "choose," it's me, if I so choose.
The stereo imaging is more pronounced, and there's also an improvement in depth (even if the layers sometimes seem a little closer together on certain recordings, which makes the sound-stage both more natural and more believable; above all, they are better defined and more distinct), enough to give a greater sense of specialization.
There's less micro-saturation when the recording (whether good or "bad") pushes the limits of the Kennerton Thridi, in both the bass and treble frequencies. On the most demanding or best-recorded tracks, I feel like I'm practically rediscovering the music; some backgrounds that were previously almost inaudible are now within reach of analysis. And from a less analytical perspective, this increased precision also allows me to relax more easily, because I can already see how much less effort my hearing has to make to compensate for the dynamics, as the sound seems "lighter"... while simultaneously gaining in texture ! (which may seem paradoxical).
Truly, what a beautiful piece of work ! Thank you again for your professionalism and the quality of your work and materials. The music is so well presented that it fills me with enthusiasm : Thanks to you, there's less distance between me and the music and the emotions it evokes...
Pierre
