In this article, I review the Lavricables V5 Master IEM upgrade cable. The Master Line sits near the top of Lavricables’ range, with prices starting at $355 USD for the IEM cable variants. It’s pitched at enthusiasts and serious listeners who want more than the average stock wires can offer.

Over the last decade, this boutique cable maker has quietly built a reputation for carefully considered designs and meticulous craftsmanship. Founded in 2012 and based in Latvia, the brand remains a small, hands-on operation, with every cable handcrafted in Europe by a dedicated team of audiophiles rather than churned out on an assembly line. That ethos shows in both build and presentation.

Disclaimer: This sample was provided by Lavricables for an honest review. All observations and opinions here are my own, based on my experience with the product.

Design

The V5 Master for IEMs is built around four cores of 5N purity (99.999%) silver AWG22 multi-strand litz wire, and that choice of materials immediately sets the tone for what this cable is trying to be. High-purity silver is prized for its excellent conductivity, and here it’s paired with a relatively thick gauge that gives the cable a more purposeful, high-end feel than the average aftermarket lead. My sky blue 1.2m sample arrived with Lavricables’ carbon fibre Y-splitter, a carbon 4.4mm balanced rhodium plug, and 0.78mm 2-pin connectors. The rhodium components are impressively discreet in practice — they don’t add unnecessary weight or bulk, and the plug in particular feels nicely balanced rather than front-heavy when connected to a portable player.

Visually, the cable is very well executed. The braid is uniform and tightly controlled from end to end, with no uneven twists or loose sections, and the translucent sky blue jacket lets just enough of the silver through to give it a clean, technical look without turning it into a flashy showpiece. It’s a design that manages to feel both modern and restrained, which suits a premium IEM cable far better than something overly decorative. The carbon hardware ties the whole thing together nicely, adding a subtle sense of cohesion rather than drawing attention to itself.

In daily use, the V5 Master is easy enough to handle. It’s reasonably supple and drapes well around the ears, although it can occasionally spring into slightly awkward shapes. It remains completely free of microphonics.

Despite being extremely lightweight, it doesn’t feel flimsy — there’s a reassuring sense of substance when you hold it, with a finish that feels carefully considered rather than purely functional. Taken as a whole, it’s a clear step up from most stock cables in both appearance and ergonomics, giving attached IEMs a more refined, purpose-built feel before even getting to the sound.

Sound

I started my listening with two IEMs I know inside out: the Noble Audio Van Gogh and the Westone MACH 60. Both are revealing in different ways, and both tend to show up changes upstream quite clearly, which makes them good candidates for cable evaluation. Straight away, the V5 Master came across as a cable aimed more at refinement than reinvention. Rather than shifting the tonal balance dramatically, it seemed to strip away a little haze, leaving the presentation feeling cleaner and better organised.

With the Van Gogh, the first thing that caught my attention was the midrange. Vocals sounded purer and more clearly outlined, with less smearing around the edges of notes. On busier tracks, where guitars and synths can crowd the centre image, there was a greater sense of separation between elements. It wasn’t a case of added brightness, but more that the signal felt less cluttered, allowing phrasing and articulation to come through more naturally. Female vocals in particular benefited from this, sounding smoother yet better defined at the same time.

Soundstage also showed a subtle but worthwhile change. The Van Gogh already throws a respectable stage, but with the V5 Master in place, depth became easier to perceive. Instruments didn’t just spread left and right, they layered more convincingly front to back. Switching over to the MACH 60 made this even more obvious. Imaging felt more stable, with instruments occupying more clearly fixed positions rather than forming a flatter, more blended wall of sound. Live recordings and sparse acoustic tracks gained a stronger sense of space, with background elements pushed slightly further away from the listener.

Bass remained true to each IEM’s inherent character, but with a touch more discipline. On the Van Gogh, sub-bass notes felt cleaner on attack, with less bloom into the lower mids. Mid-bass didn’t gain extra weight, but it did sound better controlled, which helped bass lines feel more deliberate and textured. The MACH 60, already tight in this region, came across as a little tidier and more contrast-rich through the low end, which in turn made the midrange seem clearer by comparison.

Treble was where the V5 Master made its presence most obvious. There was a mild increase in perceived air and extension compared to the stock cables I used as reference, but without pushing either IEM into sharp or brittle territory. Cymbals had a more natural decay, and fine detail in the upper registers was easier to follow without sounding forced. On the MACH 60 in particular, this translated into a presentation that felt more open and less boxed-in, while still retaining its smooth, monitor-like character.

Verdict

Taken as a whole, the Lavricables V5 Master doesn’t try to reinvent your IEMs, but it does allow them to perform with greater transparency and composure. It’s the kind of upgrade that makes a good setup feel more organised and polished, particularly with resolving monitors that can take advantage of its cleaner signal and improved spatial cues. Rather than imposing a strong character of its own, it works by tidying up what’s already there, which makes its contribution feel natural rather than forced.

There’s also a psychological side to cables that’s worth acknowledging. Expectation bias is real, but so is the simple joy of using something that looks and feels well-made. In daily use, the Lavricables V5 Master is genuinely satisfying: it’s lightweight and beautifully finished. The sonic gains may be subtle, but combined with the build and aesthetics, they add up to a cable that’s easy to enjoy as a long-term daily driver — with the sound quality very much the icing on an already tempting cake.
