Red King

This is RED KING premium

This amp is made in premium finish (white + piano ebony).

We have optimised dual power supply, which is totally separated for right & left channel and can work in all world’s AC voltage standards.

The new bluetooth is on board – this newest BT 4.0 goes in lossless streaming fashion to cancel distortions in sound and this really works. It sounds as good as your best CD can do and needs no pin code.
Power transformers are double shielded to minimize hum.

The main wood boards are 20mm thick and covered in high gloss on both sides.
The circuit is executed in point to point, pcb and smd method – depens on temperature ratio, power due to current and function of each internal submodule.

SUPERIOR tube amp

Many times we see EL84 power tube paired with ECC83 pre-amplifing ones. The ECC83 and similar triodes are weak in term of power. Bearing in mind such lack of full power kick for the most crucial power stage (EL84), we have developed one of a kind “Totally Open Throttle Concept”, which boosts astonishing sound force hidden for many decades in famous EL84 tube! It all depends on how good you will kick the power tube.

We do strongly believe, that you never had a chance to expect, that 6Watts per channel are able to move your room’s furniture. Neither do we, but for sure our 6 Watts will make them shake now! That is why our newest tube amp has been given best name for its unique sound quality: SUPERIOR.

This amplifier surpasses great majority of other SE, class A designs in terms of power punch and beam-focused sound. The SUPERIOR will bring hard kick even to your massive floorstanding speakers. To build an elegant set match the SUPERIOR with our Superioro – one-cone fullrange loudspeakers. In the SUPERIOR tube amp all five tubes work in top notch class A mode and are of specially selected military grade (5000 hours durability, instead standard tube supposed to last for 1000 hours)!

On the rear panel you can find one pair of rca analog input & optional with losless wireless extra input for any hi-tech device.

The Superior brings optimum synergy in tube design idea & sound air-streaming innovation – other reasons for calling it SUPERIOR again.

You can choose from any colour finish or even go for premium version made in ebony and white piano!

Broadband Sound Concept:
Mid-low, medium and treble frequencies go through full range double speaker system with linear characteristic, giving sound source so desired cohesion and neutrality. In practice this provides a precise and spatially-arranged musical spectrum.

Double Loudspeaker Concept:
In the KETSUS instrument power is distributed into two woofers – the main effect being two times higher output & reduced distortions.

The box in Ketsus is a multiple-reinforced casing, featuring a diagonal inner partition to prevent unnecessary acoustic reverberations. The fullrange speaker and woofer units have been adapted for separate encloasures: closed and bass-reflex type.

The cabinet structure is bulid from 20mm to 40mm panels with strong internal bracings. Additionally different wall connecting system for front and rear panels has been developed to minimize the box resonances. In KETSUS perfect damping process goes into four ways : wool blocks, bitumen mats, pyramid foam and low density damping material.

How about my room?
KETSUS are best suited for 18 to 60 sqm rooms. The lateral subwoofers in the left and right KETSUS speakers should be positioned on the system’s inside or outside – dependant on your room’s acoustics. The front panels should be exactly directed at the listener’s head.

Your KETSUS will be custom finished to suit your special needs. Just let us know your idea.

Modesty and majesty in design and golden proportions are three features placing NUVO in the eternally “simple elegance” class.

NUVO instrument combines state-of-the-art technology with innovatory engineering.

NUVO crowns 15 years of intensive work to develop high-fidelity parameters for every reproduced sound, note and beat. The system’s simple stylistics and advanced solutions make listening to music a tangible experience.

Your NUVO will be custom-made to suit your special needs. Just let us know your way.

Additional DescriptionMore Details

NUVO offers high reproduction dynamics and scope going hand in hand with acoustic precision to produce a unique tri-dimensional sound effects even from standard stereo track.
The NUVO instrument is a two-way speaker system, which works in bass-reflex mode. Despite their small dimensions the speakers have a considerable bandwidth ranging from lowest bass to ultra-treble tones far beyond human reach.
Selecting an optimum quality components for a construction makes only half of its success, although many producers believe this is all that is needed. Only continuous and painstaking adjusting will raise it to the peaks of acoustic perfection and bring the best out of each of its elements. Now you know why NUVO are the exquisite instrument beyond compare.

The EDS system consists of three chambers, two tightly packed with a special micro-sand, the third – main – chamber built with variously-angled walls to eliminate parasitic resonances.

The walls are of special 25 mm high and medium density fiberboard. Additional damping is provided by bitumen mats and fleece.

The result is a perfectly stable box made of four different materials whose specific acoustic qualities help considerably reduce and disperse all negative resonances inside the speaker.

Additional stability is provided by the system’s mass – 18 kilogrammes each!

How about my room?
The room works like an acoustic chamber often creating ill-suited surroundings which are the cause of unpleasant sound distroitions, colourations.

Below are some tips on safe loudspeaker placement. Loudspeakers should stand:
• no less than 1m* from the listener
• no less than 2.5m* and no more than 5 m from each other
• no less than 30 cm* from the back wall
• no less than 80 cm* from the side walls
• stand-mounted and free-standing loudspeakers should be positioned so that the point between tweeter and woofer is level with the listener’s ear.

This means Fresh Quality for small power tube or solid amp enthusiasts and money-pocket savers!

The speaker’s dimensions are equal to NUVO, but in FRESHQ you get super light ceramic tweeter with carbon woofers. All this to enable two times louder sound volume, comparing to NUVO at the same power – this Concept is suited for tube amplifiers in SE, PSE or P-P mode or for solid state A class amplifiers, when every Watt is of great importance.

Also with this Concept we have gained highest value for money ratio in this category.

Additional DescriptionMore Details

The FRESHQ’s woofer works in semi-labirynth cabinet. The rear port is made of wood. Woofer has been equipped with allu basket and double power magnet motor with three types of cooper rings, which delete all kind of distortions.

The ceramic tweeter is also based on double motor, plus resonance damping chamber. the above drivers are so well engineered, that simple cross-over here was enabled.

NUVO has 85dB efficiency > FRESHQ scored 4db higher – so finally they go two times louder, when getting same amount of power.
