RCA Modulation

The result is stunning, it’s another world. From the very first notes of music, in the very first seconds, even while the tube amplifier was cold (which is very surprising), there was already a revelation of both the truth of instruments and voices, an ultra-precise spatialization, an order even in the most complex compositions mixing multiple sounds, and above all, what matters most to me, a breathtaking timbre restitution.

As a side note, my wife and I held hands to share our emotion, as some musical passages moved us deeply.

Everything sounds right, and the accuracy never contradicts the richness of the timbres. The emotion is there, all the time.

Another thing, the "fatiguing" character of the Kelinac has faded. If I had to point out an area for improvement in my system with this cable, it might be that the bass is too subtle in some passages (e.g., Toccata and Fugue by André Isoir), but honestly, it completely benefits the timbres, especially in the midrange, bringing order and detail. This cable has significantly "balanced" my system, in my opinion. It has become more refined than ever before. I agree with your metaphor: it’s a fine wine that must be savored. I’m sharing its taste with you tonight.

Esprit Beta cables are a delight. I feel like I’ve upgraded my amplifier—the improvement is significant on all levels… Sound spatialization, firmer and more controlled bass.

On Agnès Obel’s album, the voice stands out incredibly and truly pays tribute to the quality of the recording. As for the highs, they have softened over time. Previously hidden details now appear (harmonics, string scrapes, etc.). There is real texture and a "physical" presence.

I used to be a hardcore "cable skeptic," believing that marketing was more about lightening our wallets than improving our listening experience. However, I followed your advice, and after only about ten hours of listening with my new cables, I must admit it’s a revolution. A listening pleasure I had never experienced with my setup—realistic live recordings, discovering the subtleties of studio arrangements. Presence, details, and musicality—I’m still blown away every time I turn it on. A thousand thanks for helping me take this step that I had long refused to take. Looking forward to what’s next...

Exceptional for the price.

Following the installation of my new speaker cables, here are some listening comments:

Jazz:
Oscar Peterson, Count Basie (p), Freddie Green (g), Ray Brown (b), Louie Bellson (d) Universal 1974 – 1998
Expanded sound spectrum,
More precise highs: drum brushes on snare finally fully audible
More percussive piano
Much "fuller" and more audible bass

Choir:
Coppini, Monteverdi, Ruffo by Le Poème Harmonique, conducted by Vincent Dumestre, 2003.
The bass voices stand out without overpowering, dissonances are much better rendered and more effective in harmony, making their purpose clearer. The timbres of the soloists are more audible.

Symphony:
Beethoven, 7th, Carlos Kleiber, live concert 1982, allegretto:
Wow! It already made me cry, but now I’m floored: the sound planes are even more distinct. It feels like the walls of my listening room are expanding.
You can hear the wood of the double basses.

Beethoven, 5th Concerto, Léo Fleischer, George Szell, 1961, live concert; adagio then rondo allegro finale:
I wish I had this version on vinyl!
Very soft, better rendering, rich nuances. The orchestra is beautifully blended in the background, as well as in the measures where it plays alone.
Flute-oboe duo magnificently rendered.
Very balanced final rondo: nuances, blending of sounds to create a single one when necessary.

Opera
Aida, "O Celeste Aida," Jussi Björling:
You can hear everything; the timbre is particularly highlighted, and even his incredible technique is more audible (I am a singer…).

Well, I’ll stop here—you get the idea, I’m thrilled with this purchase.
