Conrad-Johnson releases ART88 triode reference preamplifier

The following is a press launch from Conrad-Johnson.

The ART88 Preamplifier has been designed to function an business reference customary for line-stage preamplifier efficiency, a task crammed for greater than a decade by its legendary predecessor, the GAT preamplifier.

At the identical time, it’s notable for its comfort and ease of use. The unit options enter choice and degree adjustment by microprocessor-controlled relays, permitting degree and stability to be adjusted in 100 steps of roughly .7 dB per step. All capabilities could be managed by the hand-held wi-fi distant management. The ART88 Preamplifier might be obtainable in a numbered, restricted version of 250 items which might be offered via choose conrad-johnson sellers.

The ART88 is actually a dual-monaural preamplifier, the 2 channels sharing solely the facility transformer and chassis. The circuitry is elegant in its simplicity. Each channel’s audio circuit options two high-transconductance twin triode vacuum tubes. Gain is supplied by a composite triode of paralleled sections of 1 NOS Philips PCC88. This amplifier stage is coupled to the preamplifier outputs via a high-current buffer stage consisting of paralleled sections of a second PCC88 twin-triode. This buffer stage supplies a sufficiently low output impedance to make the ART88 suitable with a variety of interconnect cables and amplifiers. Each channel’s audio circuit is powered by its personal devoted DC energy provide that includes discrete voltage regulators that isolate the audio circuits from one another and from the AC energy line. Infrasonic noise is minimized by working the tube filaments (heaters) on a DC voltage provided by one other regulated energy provide.

Considerable care and a spotlight have been paid to the bodily facets of the design as properly. Microprocessor managed relays, used for choosing sources and degree setting, are positioned proper on the enter connectors, maintaining sign paths quick to attenuate crosstalk between channels and inputs. The degree management part and the audio circuitry are every shock mounted on unbiased daughter circuit boards to isolate the audio circuits from mechanical vibrations from the extent management relays in addition to from exterior vibrations. The elegant casework is executed in heavy gauge aluminum to help in minimizing microphonics.

Experience has taught us that the total potential of any circuit can solely be realized through the use of the best obtainable components. Each half for the ART88 has been chosen on the idea of each sonic efficiency and sturdiness. The audio circuit (together with the extent management) is executed solely with precision metallic foil resistors and proprietary CJD Teflon capacitors. Tubes have been rigorously hand chosen for minimal noise and microphonics. The DC regulated energy provides use the identical high quality resistors because the audio circuits. Capacitors for the facility provides are completely CJD polypropylene and Teflon – there aren’t any electrolytic capacitors within the audio circuits or their associated energy provides. All sign switching is completed by particular relays designed for sign purposes. These relays are sealed and have gold plated silver contacts. Input and output connectors are machined from oxygen free copper, and are silver plated with a Rhodium flash.

Analog Technology Switzerland introduces its first cartridge, the Nagra Reference MC

The following is a press release from Analog Technology Switzerland.

Swiss high-end audio firm, Nagra, announces the upcoming release of its first phono cartridge – the Nagra Reference MC cartridge. Initial units are scheduled to be delivered in December.

The Nagra Reference MC cartridge is the product of a number of years of intense R&D supplemented by extensive listening tests. This moving coil cartridge will be available in 4 and 6 Ohm variants. Designed in parallel with the Nagra 70th Anniversary Reference turntable/tonearm system, it is an ideal companion component to complete the ultimate LP playback platform.

The Reference MC cartridge features a number of significant and unique elements. While traditional moving coil transducers utilize a single layer coil body, the Nagra Reference MC cartridge employs a multi-layer transducer featuring a double layer coil body wound with hyper-pure silver windings. The 6 Ohm Reference outputs 0.45mV @ 5cm/S. The 4 Ohm Reference achieves an output of 0.30mV @ 5 cm/S.

A stiff ruby cantilever is mated to a high strength titanium structure featuring a DLC (diamond-like carbon) coating. The titanium structure utilized in the coil body/cantilever interface addresses a traditional source of resonance and substantially reduces vibration unrelated to the musical signal. The stylus tip is a Swiss produced, Fritz Gyger S profile chosen for its wonderful combination of detail retrieval and musicality.

Further evidence of the obsessive attention to detail in the cartridge’s design is found in the connector pins. Those employed in the Reference MC cartridge eliminate the commonly found connection joint between the pin and the coil. In the case of the Reference MC, the pin is a continuous single piece from itsexternal end point to its internal point of contact with the coil, resulting in a welcomed lowering of inductance.

In addition to the extensive focus on the generator system and groove/stylus/cantilever interface, Nagra’s team of engineers and designers paid great attention to the Reference MC cartridge body. Substantial material science investigation lead the team to a unique, non-ferrous alloy called EXIUM AM. Born from aerospace materials research, EXIUM AM is the result of a collaboration between the CNES (the French equivalent of NASA), the Ecole de Mines de Paris and the French firm LBI Foundries. It was developed to address the need for an alloy with very high damping properties – a necessary attribute for a particular Mars mission whose purpose was to measure minute seismic activities on the red planet. Nagra engineers determined that this high damping characteristic alloy was perfect for use in audio applications where the elimination of unwanted vibrations and resonances is an extreme priority. As a result, the Reference cartridge utilizes an EXIUM AM inlay at the critical interface between cartridge generator and the cartridge body. (An examination of Nagra’s 70th Anniversary Reference turntable will reveal that the table’s platter features a precisely CNC machined ring of EXIUM AM.) Nagra’s use of EXIUM AM is exclusive. Nagra has secured the sole worldwide right to use EXIUM AM in audio products. In order to produce a cartridge of optimal weight for the Reference Anniversary tonearm, while maintaining high internal damping properties, a proprietary super magnesium alloy is utilized for the balance of the cartridge body.

The Nagra Reference cartridge has exceptional tracking ability, resonance control and exemplary specifications. It will match most tonearms and phono stages but will reach its ultimate potential when paired with the Nagra Reference turntable/tonearm system and Nagra phono stages.

As these highlights indicate, Nagra is committed to being a world leader in state of the art LP playback products. We look forward to the upcoming release of the Nagra Reference MC cartridge. We are anxious for serious vinyl lovers around the world to experience their collections like never before.
