Denon DL103 is a MC (moving coil) phono cartridge made by DENON company.
The DL103 was designed for professional broadcast use in 1962 using the arms and turntables of the day. Production has continued uninterrupted since then. There are available different versions upgraded by other companies or individuals involved in DIY audio.
Despite being designed in the 1960s it is still one of the masterpieces in audio technology and can easily compete with contemporary constructions. Due to its construction, Denon DL-103 is recommended as one of the very few cartridges suitable for heavy tonearms. (like in Lenco or Garrard turntables) As a low-output phono cartridge it requires either a step up transformer for a standard MM phono preamp, or phono preamp with built-in MC input.
The RCA connector is a type of electrical connector commonly used to carry audio and video signals. The name RCA derives from the company Radio Corporation of America, which introduced the design in the 1930s. The connectors male plug and female jack are called RCA plug and RCA jack.
A DI unit is an electronic device typically used in recording studios and in sound reinforcement systems to connect a high-output impedance, line level, unbalanced output signal to a low-impedance, microphone level, balanced input, usually via an XLR connector and XLR cable. DIs are frequently used to connect an electric guitar or electric bass to a mixing console's microphone input jack. The DI performs level matching, balancing, and either active buffering or passive impedance matching/impedance bridging to minimize unwanted noise, distortion, and ground loops. DI units are typically metal boxes with input and output jacks and, for more expensive units, “ground lift” and attenuator switches.
A magnetic cartridge, more commonly called a phonograph cartridge or phono cartridge or (colloquially) a pickup, is an electromechanical transducer that is used to play records on a turntable.
Line level is the specified strength of an audio signal used to transmit analog sound between audio components such as CD and DVD players, television sets, audio amplifiers, and mixing consoles.

Denon is a Japanese electronics company started in 1910 by Frederick Whitney Horn, an American entrepreneur. Denon produced the first cylinder audio media in Japan and players to play them. Decades later, Denon was involved in the early stages of development of digital audio technology, while specializing in the manufacture of high-fidelity professional and consumer audio equipment. Denon made Japan's first professional disc recorder and used it to record the Hirohito surrender broadcast. For many decades, Denon was a brand name of Nippon-Columbia, including the Nippon Columbia record label. The Denon brand came from a merger of Denki Onkyo and others in 1939. In 2001, Denon was spun off as a separate company with 98% held by Ripplewood Holdings and 2% by Hitachi. In 2002, Denon merged with Marantz to form D&M Holdings. On March 1, 2017, Sound United LLC completed the acquisition of D+M Holdings.
Roksan is a British manufacturer of high fidelity audio products for domestic use, based in Rayleigh, Essex. It is best known for its influential and innovative design for hi-fi equipment, and in particular its Xerxes platform for playing LP records.
RIAA equalization is a specification for the recording and playback of phonograph records, established by the Recording Industry Association of America (RIAA). The purposes of the equalization are to permit greater recording times, to improve sound quality, and to reduce the groove damage that would otherwise arise during playback.
Musical Fidelity is a British producer of high-end audio equipment focusing on streaming music players, and its core product range of amplifiers of various types. Other products have included headphones, Digital-Analog Converters (DACs), CD players, Bluetooth Receivers, ‘all-in-one systems’. Founded in the United Kingdom in 1982, they are known for their unusual industrial design, Nuvistor tube use and Class-AB amplifiers.

Scratch Live is a vinyl emulation software application created by New Zealand based Serato Audio Research, distributed by and licensed exclusively to Rane Corporation. Serato was first known for its Pro Tools plug-in, Pitch N Time, which was sold predominantly to the film industry.
The Technics SL-10 is a direct-drive, linear tracking automatic turntable, which was produced from 1979 to 1985.
The TRM-800 was a high-end solid state integrated stereo amplifier made in Japan, using NEC power transistors, by Nikko. It was the top-of-the-line model in the Nikko amplifier range of TRM's series; housed in a wooden walnut-finished cabinet and a brushed aluminum front panel, was introduced in 1975 the same year as the Marantz 2235. It was a two-channel amp; however, it had three sets of speaker connections; those powered selected by buttons. At 8 ohms, the amp could put out 65 Watts per channel RMS, delivering superb high fidelity sound with exceptional tone quality. Unlike many amps of this time, however, the TRM-800 was stable at lower impedances than 8 ohms; down to 4 ohms. The TRM-800's frequency response ranges 10Hz to 40.000 Hz ±1 dB with T.H.D. less than 0.1% at rated output. Its preamplifier and main amplifier were separable for multi-channel amplifier systems. The amp has internal circuit breakers which prevent it from clipping or overheating. Its power consumption is 250 watts. For equalization it has only a bass and a treble knob; however the frequency of these are selectable; between 250 and 500 Hertz for the bass, and between 2.5 and 5 kHz for the treble. It also has a high, low, and a subsonic filter. There are two phono stages; phono 2 is provided with impedance matching selection, for using different types of cartridges (MC/MM).
Nominal impedance in electrical engineering and audio engineering refers to the approximate designed impedance of an electrical circuit or device. The term is applied in a number of different fields, most often being encountered in respect of:
The Roksan Xerxes transcription turntable is a record player named after the Persian king Xerxes I and produced by London-based Roksan Audio. Designed by Roksan co-founder, Touraj Moghaddam, the Xerxes is a belt-driven turntable with a solid plinth. Launched in 1985, the sound quality of the product positioned it as a strong competitor against the established industry leader, the Linn Sondek LP12. Many reviewers use the Xerxes as a reference turntable.
The Naim NAIT is an integrated amplifier from the British hi-fi manufacturer, Naim Audio. The original NAIT is one of the most recognisable pieces of hi-fi equipment ever made. Hi-fi critic Lucio Cadeddu recognised its legendary status, referring to it as "one of the most controversial and famous integrated amps in the history of HiFi".
Naim Audio is a specialist British manufacturer of high-end audio amplifiers well known for their self described qualities of "pace, rhythm and timing".
The NAD 3020 is a stereo integrated amplifier by NAD Electronics, considered to be one of the most important components in the history of high fidelity audio. Launched in 1978, this highly affordable product delivered a good quality sound, which acquired a reputation as an audiophile amplifier of exceptional value. By 1998, the NAD 3020 had become the most well known and best-selling audio amplifier in history.
Compatible Discrete 4, also known as Quadradisc or CD-4 was as a discrete four-channel quadraphonic system for phonograph records. The system was created by JVC and RCA in 1971 and introduced in May 1972. Hundreds of recordings using this technology were released on LP during the 1970s.
The Audio-Technica AT-LP120 is a mid-range direct-drive turntable introduced in 2009 by the Japanese audio equipment manufacturer Audio-Technica. The AT-LP120 was intended to be a viable replacement for the long-running Technics SL-1200 series of turntables that was set to be discontinued in 2010. It supports both phono and line-level output using a built-in preamplifier.
