With a perfect blend of tube smoothness and an almost unbelievable level of detail and transparency, the new RP-7 essentially redefines what a reference level tube preamplifier can achieve.

The RP-7 is our first balanced preamplifier designed on the cutting edge RP-X hardware and software platform and every aspect of the RP-7 design is aimed at maintaining near perfect signal integrity. Beyond the computer optimized circuit topology, all of the capacitors, resistors and other critical parts are of ultra-high quality assuring the highest sonic integrity. The sophisticated electrical design is based on pure class A tube amplification with mosfet output buffering to provide huge drive along with a super low output impedance.

Beyond the excellent sound, the feature rich RP-7 provides all of the functions demanded of a luxury hi-end preamp. Included are a home theater bypass, processor loop, mono button, defeatable display, slow start circuitry, and a host of other features. A full function remote provides additional convenience. Two pairs of XLR balanced inputs and three pairs of RCA line level inputs allow for numerous source components while two pairs of XLR balanced outputs along with two pairs of RCA variable outputs facilitate a wide range of output connectivity. Also included is a high power tube based headphone amplifier capable of driving even the most difficult headphones.

The attractive industrial design includes an easy to read OLED display that further enhances the preamp's sleek and elegant appearance. The display provides all relevant information in large easy to read azure tinted characters. The ultra-high quality tactile buttons and knobs further add to the exclusive feel of the RP-7.

Elegantly simple yet technically sophisticated, the RP-1 is our latest tube preamplifier based on the innovative RP-X platform. Stunning in both performance and design, the RP-1 provides all of the features you need for a truly high end system. Boasting outstanding specs and remarkable sonics, the RP-1 sets a new benchmark in affordable performance and functionality.

Beyond its superb preamplifier capabilities, the RP-1 offers numerous features to further enhance your listening experience. The onboard MM/MC phono has user adjustable gain settings of 43 and 58 dB to accommodate most popular cartridges. A wide variety of loading options also means your favorite cartridge can be configured to sound its very best. The discrete 1 Watt headphone amplifier will thrill you with its smooth and refined sound. Other features include home theater inputs for easy integration into your theater system, two pairs of variable outputs and a pair of fixed outputs. The seven button remote allows you to conveniently access volume, balance, selector and mute functions from your listening position. The elegant appearance of the RP-1 is further enhanced by an easy to read OLED display that provides volume, balance and source information in large easy to read characters. The display can also be turned off if desired.

The RP-5 is our first preamplifier based on the groundbreaking new RP-X platform. Silky smooth yet extraordinarily high tech, the RP-5 sets a new benchmark in performance and functionality. Utilizing four 12AU7 tubes in a mu-follower configuration, the computer optimized circuitry boasts outstanding sonics as well as industry leading specs.

The RP-5 offers much more than just sonic excellence with numerous features to further enhance your listening experience. The onboard MM/MC phono has user adjustable gain settings ranging from 40 to 60 dB. A wide variety of loading options means your favorite cartridge can be configured to sound its very best. A tube based headphone circuit offers smooth and detailed sound for your late night personal audio sessions. Other features include home theater inputs, a processor loop and mono button. The ten button remote allows you to conveniently access volume, balance, selector, mute, mono and on/off from your listening position.

The elegant appearance of the RP-5 is enhanced by an easy to read VFD display that provides volume, balance and source information in large easy to read characters.

​New for 2014 the MK II version of Belles LA-01 line stage preamplifier features state of the art performance and musicality. The LA-01 achieves its ultimate in musical performance by keeping the signal path as simple and direct as possible. In order to accomplish this, it uses a totally minimalist design approach. This preamplifier is strictly a dedicated stereo pre-amplifier of the highest calibre.Those listeners wishing to immerse themselves inside the envelope of 'pure musical connection'. The MK II LA-01 delivers with aplomb.

The LA-01 MK II features a ultra low noise high quality separate power supply, housed in an dedicated enclosure that is perfectly matched to the preamplifier structure. The power supply is balanced designed with six stages of decoupling and filtration to totally isolate it from the incoming mains power line, making it seem like a battery powered unit. The areospace materials used in the LA-01 aids in providing a rigid structure to eliminate mechanical feedback vibrations. For, example the top and button covers are constructed from 6mm thick aluminium. The side and rear panels are 9mm, the front panel is constructed from 16mm aluminium. Both enclosures are decoupled from its mounting surface with Black Ravioli O.E. feet as standard.

The LA-01 has four unbalanced stereo line inputs and two main stereo unbalanced outputs. The line stage features an ultra low distortion high input impedance direct-coupled amplifier with zero output impedance. The output stage features power mosfets which can drive vitrually an power amplifier to produce incredible dynamics, and realism. Yet portray musicians with a delicacy and naturalness whilst delivering the interplay, textural rendering and spatiality that only some of the very best units can provide.

LA-01 Mk2​     $8,495

​The performance and engineering found in the Belles 22A is typically reserved for higher priced components. Internally the 22A utilises a hybrid vacuum tube design.

The unit uses two 12AU7 valves in conjunction with power mosfet regulators. Also providing isolation from the power supply, which in turn greatly improves the stereo imaging.

Distortion on the Belles A22 is extremely low, which brings out the dynamics and detail, within the music. The emitter follower output is biased with a constant current source instead of a resistor.

Belles 22A pre amplifier has been designed to remove variances in vacuum tube behaviour due to manufacturing indifferences and tube aging.

Externally the Belles A22 is visually a work of art. The entire chassis is made of brushed anodised aluminium. The front panel is 38mm thick, machined and engraved, come in either Black or Silver.
