HumminGuru: The Engineering Behind Pure Analog Performance
In the world of vinyl, high fidelity begins with the record itself — first and foremost with the condition of the groove that carries the musical information. But it also depends on rotational stability, control of static electricity, and the cleanliness of the stylus.
Analogue playback is a chain of mechanical precision, and HumminGuru understands this principle at its core. That is why the brand doesn’t simply make products or accessories; it builds a complete ecosystem for vinyl care and optimisation — engineered with industrial discipline, technological consistency, and a clear audiophile philosophy.
From ultrasonic cleaning systems to static-control tools, from precision record stabilisers to high-quality inner sleeves, HumminGuru’s solutions are made for those who treat their collection not as objects, but as a living musical archive.
At Athens Pro Audio, the full HumminGuru range is presented for what it truly is: an investment in the very source of sound.
The Science of Ultrasonic Cleaning
Before we talk about models, it’s worth pausing on the technology itself. Ultrasonic cleaning is based on the creation of microscopic bubbles through high-frequency sound waves (40 kHz). When these bubbles collapse, they generate micro-impacts that dislodge contaminants from the groove walls without mechanical abrasion.
In practice, that means:
- Deep cleaning into micro-grooves
- Removal of residue that brushes simply can’t reach
- Reduced surface noise
- Preservation of groove geometry
In a high-resolution system, the difference is not only measurable — it is unmistakably audible.
NOVA
The Ultimate Expression of Mechanical Precision
NOVA isn’t merely HumminGuru’s flagship proposition. It is the brand’s most mature engineering statement: an ultrasonic cleaning system designed with clear priorities — consistency, repeatability, and serious archive-level record management.
Unlike simpler implementations, NOVA offers an adjustable cleaning cycle of up to 10 minutes. This isn’t for show; it exists for controlled exposure of the record to the ultrasonic field. For heavily used records or discs with a long and “busy” history, the longer duration allows deeper penetration and a gradual release of contamination trapped inside the micro-grooves.
Cavitation Density: The True Heart of Cleaning
The performance of an ultrasonic cleaner isn’t defined by operating frequency alone (40 kHz). It is defined by the density and stability of cavitation — how many microscopic bubbles are generated in the fluid, and how evenly they are distributed across the tank.
With NOVA, the ultrasonic field is controlled and stable, ensuring a high cavitation density without excessive intensity that could compromise the record surface. The bubbles form and collapse consistently, penetrating deep into the grooves and removing debris without friction. The result is not cosmetic cleaning — it’s structural cleaning.
Rotational Exposure Logic: Why Stable Rotation Matters
Rotation is just as critical. HumminGuru has invested heavily in NOVA’s rotational exposure logic. Rotation speed remains stable, without micro-surges or inconsistencies. The record is exposed evenly to the ultrasonic field, avoiding so-called “dead zones” — areas that, in less refined systems, may not receive equal cleaning energy. This consistency delivers repeatable results. Every record that passes through NOVA receives the same balanced treatment. In analogue, repeatability is reliability.
Controlled Drying
The drying stage in NOVA isn’t simply airflow. It is controlled air circulation, with optimised flow that removes moisture evenly and reduces the risk of residue or re-adhesion of particles. The result is a record that is fully ready for playback, without secondary handling. In practical terms, this means a workflow that respects your collection — no extra stages, no unnecessary manipulation. NOVA completes the process with precision.
Build Quality and Design Consistency
A rigid chassis, low operating noise, and a discreet aesthetic place NOVA closer to a reference tool than a domestic appliance. HumminGuru maintains a clear design identity: understated, functional, serious. Nothing is decorative. Everything serves the process. What does this mean in listening terms? In a high-resolution system, the improvement isn’t a theatrical “change of character” — it’s a foundational upgrade.
After a NOVA cycle:
- The background becomes deeper, with a clear reduction in surface noise
- Microdynamics emerge, and previously masked detail becomes tangible
- High frequencies gain cleaner articulation
- Low frequencies become more stable and controlled
- Imaging locks into sharper focus
Across international audiophile communities, NOVA has been described as a “serious archival solution” — a phrase not given lightly.
Who Is NOVA For?
NOVA isn’t aimed at the occasional listener. It is designed for collectors with extensive libraries, owners of high-resolution systems, and anyone who treats vinyl as an archive — not merely a playback medium. With NOVA, HumminGuru makes a clear statement: ultrasonic cleaning is not a luxury, but a fundamental requirement for reference-level analogue performance.

Ultrasonic Vinyl Record Cleaner
A Benchmark Proposition
HumminGuru’s core ultrasonic unit didn’t become popular by accident. Internationally, it has established itself as one of the most balanced and meaningful solutions in its category — because it delivers the essence of ultrasonic technology without needless complexity. It operates at 40 kHz, the industrial standard for precision cleaning, producing stable cavitation. The density of microbubbles in the fluid is sufficient to reach deep into micro-grooves, removing contaminants that mechanical methods simply cannot address.
Stability and Repeatability
The value of this unit is not found in “impressive” numbers, but in stability. Its automatic wash-and-dry cycle is designed to deliver repeatable results without constant user intervention. Record rotation remains stable and controlled, ensuring uniform exposure to the ultrasonic field.
This rotational exposure logic — the right balance of speed and time — ensures every section of the record surface receives equal treatment. It’s not complexity for complexity’s sake. It’s disciplined mechanical simplicity.
Filtered Water System
A practical advantage is its water filtration and reuse system. Filtration reduces the build-up of particles in the fluid, keeping the cleaning process effective across multiple cycles.
This delivers two key benefits:
- Consistent results
- Lower resource consumption
- The philosophy is clear: functional design with respect for long-term use.
Compact Design, Serious Output
Compared with larger professional units, the HumminGuru Ultrasonic Vinyl Record Cleaner remains compact and visually discreet. It integrates easily into a listening room without dominating the space. Build quality remains consistent with the HumminGuru ethos: a rigid frame, low operational noise, and clean ergonomics. It isn’t a laboratory tool. It’s a home tool with a professional mindset.
What Changes in Practice?
The first encounter with a properly cleaned record reveals differences immediately:
- Reduced surface noise
- Cleaner silences between tracks
- Better treble articulation
- Greater stability through the midrange
As with NOVA, in high-resolution systems the gains in microdynamics are obvious — small information previously covered by noise acquires real presence. In audiophile circles, this unit is often described as an “entry to serious ultrasonic cleaning”, because it marks the first true step beyond manual methods and carbon brushes.
Who Is It For?
The HumminGuru Ultrasonic Vinyl Record Cleaner is aimed at music lovers who want a reliable entry point into ultrasonic cleaning, collectors with medium-sized libraries, and listeners who want meaningful improvement without stepping into flagship territory. Here, the essential balance is achieved: technology without excess, performance without unnecessary complication, and serious results without a disproportionate cost. For many vinyl enthusiasts, this is the first genuine move towards real record archive management.
EZ Vinyl Record Washer
The Smart Upgrade
The EZ Vinyl Record Washer is the most accessible entry into ultrasonic cleaning — without abandoning HumminGuru’s core principle: stable, controlled, repeatable performance. It was not designed as a “simplified” solution. It was designed as an approachable expression of the same technological philosophy. Operating at 40 kHz, it uses cavitation to remove micro-particles from the grooves, where manual methods barely reach the surface. The ultrasonic field is tuned to deliver meaningful cleaning without demanding complex settings or technical expertise.
Proper Mechanical Simplicity
EZ is built around balance. Stable rotation, a controlled cycle, and user-friendly ergonomics create a system that performs reliably from the very first run. Rotational exposure remains uniform, ensuring the record is treated evenly by the ultrasonic field. This isn’t a “lite” implementation — it’s a simplified way to manage a mature technology. Unlike manual cleaning kits, where results depend on pressure, angle and technique, EZ delivers consistent outcomes by design.
What Changes in Listening?
The improvement is instantly recognisable:
- Reduced surface noise and artefacts (clicks, crackle, etc.)
- Cleaner treble articulation
- Smoother transition through the midrange
- Better stereo focus
On older records, restored clarity can be genuinely impressive. On new pressings, EZ works preventatively, removing manufacturing residue and micro-particles before first play.
Build Quality
Despite its accessible positioning, EZ maintains HumminGuru’s build standards: a solid body, a clean design language, and a discreet aesthetic that sits naturally in any listening setup. It isn’t a one-use tool. It’s a long-term care device.
Who Is It For?
EZ is ideal for:
- Collectors taking their first serious step into ultrasonic cleaning
- Upgrading from manual methods and carbon brushes

Orbit Vinyl Record Static Remover
Neutralising the Invisible Enemy

In analogue playback, static electricity is one of the most underestimated sources of degradation. It may not always be visible, but it is clearly audible. Static charge attracts dust, increases surface artefacts (clicks, crackle), and can undermine tracking stability. In dry environments — or with acrylic platters — the problem can become even more pronounced. Orbit is designed to address precisely this “invisible noise”.
Dual Plasma Ion Technology
Orbit uses dual plasma ion emitters, generating positive and negative ions that neutralise static charge directly on the record surface. Unlike traditional anti-static brushes, which often reduce charge only superficially, Orbit delivers active neutralisation. The process requires no contact: discharge happens through controlled ion emission at a safe distance. The result is immediate and repeatable.
Why It Matters
Static doesn’t just add clicks — it introduces instability. Charge affects the stylus’ movement within the groove and encourages particle concentration on the surface. After using Orbit, the difference is often described as: cleaner silences, fewer micro-interferences, more stable imaging, and a less “electrical” sensation in the treble. This isn’t a dramatic change of character. It is a deeper refinement of playback.
A Perfect Partner to Ultrasonic Cleaning
Ultrasonic cleaning removes contamination from within the groove, but static can return during storage or when placing the record on the platter. Orbit is ideally used as the final step before playback. Combined with ultrasonic cleaning, it completes the record-prep chain.
Build Quality and Ergonomics
Like all HumminGuru products, Orbit combines solid construction with a discreet, elegant aesthetic. Operation is simple: no settings, no contact, no technique. Only the awareness that pure analogue performance begins with controlling even the smallest variables.
Who Is It For?
Orbit is designed for:
- Collectors who want stability in playback
- High-resolution systems where small gains are obvious
- Dry environments
- Acrylic platter users
Static is invisible — its effects are not. With Orbit, HumminGuru adds one more critical stage to analogue control, where detail becomes consistency.

S-DUO Pro
Where Fidelity Is Decided
In analogue playback, the stylus is the point where mechanical information becomes electrical signal — the moment of truth. Dust and residue accumulating on the stylus don’t just dull clarity; they alter tracking geometry. Even the smallest deviation translates into:
- Increased distortion
- Loss of micro-detail
- Treble harshness
- Accelerated wear of both stylus and groove
S-DUO Pro was designed to address exactly this microscopic but critical variable.
Controlled Cleaning Without Stress
Unlike aggressive brushes or questionable gel pads, S-DUO Pro is built around controlled contact and stable application. Its design ensures the stylus is cleaned without lateral pressure — crucial for protecting the cantilever.
Its mechanical precision allows:
- Cleaning without shifting the cartridge
- Stable vertical application
- Minimised risk of wear
The philosophy is clear: clean with respect for mechanical sensitivity.
Why It Matters So Much
A stylus reads groove modulations measured in microns. Build-up alters the effective contact area (the true contact surface), compromising tracking stability and raising perceived noise.
With a clean stylus, you can expect:
- Cleaner high-frequency reproduction
- More stable stereo focus
- Reduced micro-distortions
- Smoother performance through complex passages
In high-resolution systems, this isn’t merely noticeable — it’s expected.
Small Scale, Major Impact
S-DUO Pro doesn’t impress with size. It impresses with consistency. Used before serious listening, it becomes a stabilising factor in cartridge performance. In audiophile circles, stylus care is considered essential routine — not optional. HumminGuru translates that logic into a tool that delivers controlled results without risk.
Build Quality
As with the rest of the range, S-DUO Pro combines solid construction, clean design language, and functional simplicity. No complicated settings — just a safe, repeatable process.
It isn’t a gadget. It’s a precision tool.
Who Is It For?
S-DUO Pro is for:
- Owners of high-quality MM and MC cartridges
- Collectors seeking consistent performance over time
- Systems where micro-detail truly matters
Analogue fidelity is not only defined by the system — it is defined by the care you apply to it. With S-DUO Pro, HumminGuru reminds us that detail isn’t excess. It’s foundation.

LUMI Record Stabiliser
Stability You Can Hear

Analogue playback is mechanical by nature: the record spins, the stylus tracks, vibrations travel. Any micro-movement or imperfect contact between record and platter compromises signal stability. LUMI was designed to address precisely this: mechanical instability. This is not simply a weight. It is a controlled stabilisation system.
Mechanical Logic and Micro-Motion Control
Records aren’t always perfectly flat. Warps, surface deviations and small irregularities create micro-variations in stylus movement — both vertically and laterally.
These micro-variations affect:
- Low-frequency stability
- Phase and stereo imaging
- Microdynamic performance
LUMI improves record-to-platter contact. Through uniform pressure and balanced mass distribution, it reduces micro-movement and limits unwanted vibration — without overloading the bearing. It maintains the correct equilibrium.
Mass Loading vs Mechanical Coupling
Many stabilisers rely purely on increased mass. HumminGuru takes a more controlled approach: mechanical coupling with balanced weight distribution.
That means:
- Improved contact without bearing overload
- More stable rotation
- Reduced micro-resonances
- The result isn’t “more bass”. It’s better-controlled bass.
What Changes in Listening?
LUMI’s benefit is most apparent in systems capable of high, detailed resolution:
- Tighter, more stable low end
- Improved image focus
- Cleaner transitions through dynamic peaks
- Reduced small “smearing” in playback
It doesn’t alter your system’s character — it stabilises the whole.
Aesthetics and Build Quality
LUMI follows HumminGuru’s design language: minimal, clean, discreet. Finish quality and solidity reinforce that this is a serious tool, not decoration. Operation is simple: place it on the spindle, stabilise — no settings, no complexity.
Who Is It For?
LUMI is aimed at:
- Mid- and high-resolution systems
- Turntables with lighter platters or acrylic surfaces
- Collectors seeking mechanical consistency
- Users wanting to reduce micro-resonances
In analogue, stability is a prerequisite. With LUMI, the mechanical side of care is completed — where rotational precision becomes playback precision.
I-Brush 5-in-1 Record Cleaning Kit
The Routine That Makes the Difference

If ultrasonic cleaning is the deep-care stage, daily maintenance is what preserves the result. The I-Brush 5-in-1 kit is designed as a systematic preparation tool before and after playback. It doesn’t replace ultrasonic cleaning — it complements it.
By combining cleaning surfaces, controlled fluid application, and wet/dry separation, it allows:
- Removal of surface dust before listening
- Reduction of particles after use
- Avoidance of recontamination
Build quality and ergonomics remain true to HumminGuru’s identity: functional seriousness without excess. Record preparation matters — it is not secondary, but part of the listening experience itself.
12" Premium Inner Record Sleeves
Protection Without Compromise
Vinyl care doesn’t end at cleaning. Storage determines long-term preservation.
HumminGuru’s Premium Inner Sleeves use a 3+1 layer construction:
Three layers of HDPE (30 micron)
One layer of archival rice paper
High-density, acid-free materials protect against chemical degradation over time. Anti-static behaviour reduces charge build-up and limits particle attraction. These sleeves aren’t an accessory — they are a preservation method.

12" Anti-Static Inner Record Sleeves
Everyday Security for Every Record
For systematic use — and for replacing old, worn inner sleeves — HumminGuru’s Anti-Static Inner Sleeves are an ideal solution.
Lightweight, functional and anti-static, they reduce:
- Static charge
- The risk of micro-scratches
- Dust build-up
In many cases, replacing old paper sleeves is the simplest yet most meaningful upgrade. Protection begins with storage.
In Summary
A Six-Step Care Protocol
