Integrated Amplifiers - Musical Fidelity

An integrated amplifier goes in between your bookshelf or floorstanding speakers and music source (streamer, DAC, CD player, etc). An integrated amplifier combines a "Pre Amplifier" and "Power Amplifier" in a single box. These are the most popular type of amplifiers and offer excellent value for money. Many of the models below are award winners and all are available to demo in our showroom by appointment. If you need amplifier and/or speaker matching advice, call or email us for advice. All prices include free UK delivery and we offer low cost international shipping (check prices when you've added the items to your basket).

An integrated amplifier is an all in one unit which combines both a Pre Amplifier and a Power Amplifier, eliminating the need for extra boxes and ultimately saving space. When purchasing an amplifier or hi-fi system on a budget, an integrated amplifier is virtually always the best sounding and most cost effective solution, and many models can sound stunning. Integrated amplifiers can vary in the technology used, whether that is Class D, transistor or valve amplifiers.


Musical Fidelity presents best-in-class quality hi-fi components conceived from over thirty years of audio expertise. They design and engineer impactful hi-fi separates hosting excellent sound, high technical performance, exceptional value for money and remarkable build quality.

Musical Fidelity has designed and manufactured Hi-Fi electronics for more than thirty years and are among the best-known brands in the Hi-Fi industry. They aim to deliver exceptional music and tackle the challenge of world-class engineering. Each new design approach seeks the absolute best solution and embraces cutting-edge technologies as well as refining traditional methods for better performance.

Founder Antony Michaelson designed and produced his first amplifier, The Preamp, for his own home as he was frustrated by the mediocre preamp in his audio system. It was heard by an audio dealer who placed an order for some and they were so successful that they all sold over their first weekend on display. Consequently and almost by accident, Musical Fidelity was launched in 1982 and The Preamp received glowing reviews. It was then followed by the shoebox-style Dr Thomas power amp.

Over almost four decades, Musical Fidelity has introduced an impressive line of products from the A1 integrated amp in 1984, A370 Power Amp and Digilog; the World’s first high-end DAC. Their technologies were always at the forefront of the industry; The MVX preamp was the first in the world to combine tube circuit topology with transistors, the SA470 power amp ran 99% in Class in 1988 which facilitated the release of the A1000 four years later featuring pure Class A power amp section.

The 90s saw in the classic valve-driven Tubalog DAC, X Series with X-10D Class A triode line stage, X-ACT DAC and X-24K upsampling DAC as well as the X-Ray CD player. The Nu-Vista Preamp employing compact, metal-cased nuvistor tubes sold out within three months of launch in 1997. These formed the basis for upgraded models like the futuristic CD-PRE 24 combining a high-quality CD transport/DAC/preamp and the Nu-Vista M3 pre/power amp with discrete Nu-Vista power amp modules and choke regulation.

The Tri-Vista series offered the world’s first audio application of trivistor tubes and the kW 500 super integrated amp employed twin-triode tubes. In 2003, Musical Fidelity released their first turntable; the limited-edition M1 which was regarded as one of the best-engineered decks then went on to become a collector’s item fetching above its original price.

The supercharged X-DAC V8 introduced switchable tube buffer and extra-heavy-duty power supply and the brand won their first EISA award with the X-150 (2004-2005) for European Stereo Amplifier of the Year. KW250S packs in dual 250-watt monobloc amps, tube hybrid preamp, phono stage, 24-bit 192K upsampling CD player, FM/DAB tuner and iPod input.

Titan, launched in 2009, is a 1kW p/ch twin monobloc design with external power supply alongside the Reference-standard Primo pure Class A pre-amplifier with 14 hand-picked ECC81 tubes. Their most recent additions aim to satisfy all budgets and hi-fi needs. These include the EISA award-winnng M1 CLiC which brings together analogue and digital sources, their finest digital AMS CD/DAC and the world’s most advanced pure Class A amp; the AMS100.

Now owned by an Austria-based independent specialist Audio Tuning, the brand retains its proud British heritage and preserves the natural authentic audio performance that has become synonomous with Musical Fidelity across the world. The unique product series accommodate traditional and contemporary requirements from high quality vinyl listening, bit-perfect CD playback or increasingly popular wireless music streaming. For each source, Musical Fidelity supplies a broad range of powerful, state-of-the-art amplifiers that sound at home anywhere.

Integrated amplifiers feature speaker terminals to connect to a pair of speakers. These terminals typically accept banana plugs, spade plugs and bare wire, though they can vary so it is worth checking the amplifier offers the type of connection that matches your speaker cable. Naim amplifiers for example only accept 4mm banana plugs or Naim’s own proprietary plugs and therefore cannot be used with bare wire. Other manufacturers such as Cyrus also use their own speaker connections, known as BFA, which require speaker cable terminated with BFA plugs rather than spade plugs, banana plugs or bare wire. Some integrated amplifiers feature two sets of speaker outputs, allowing you to switch between two separate sets of speakers or even use multiple pairs simultaneously.

When purchasing an integrated amplifier, just as with a power amplifier, it is important to consider its power rating and whether it is suitably powered to drive the speakers you intend to use. Most speakers are given a recommended power rating, stating the range of amplifier power outputs suitable for optimum speaker performance. If your integrated amplifier is too low powered for your speakers then the overall sound, impact and soundstage will suffer from your speakers not being driven properly. If an amplifier is too powerful, sound can also suffer and you may even risk damaging your speakers.

Integrated amplifiers feature a range of input and connectivity options, thanks to the pre amplifier which is included in the design. This enables you to connect a range of sources to your amplifier, typically via RCA inputs, although a range of other connectivity options exist. Some amplifiers will feature a headphone output, allowing you to use a pair of headphones rather than your main speakers, making private or late night listening very simple. Many integrated amplifiers will also feature a phono input, which enables you to connect a turntable directly to your amp without the need for a phono stage in between. Some models even include an on-board DAC, allowing you to connect digital sources such as a computer, CD player or streamer and enjoy high quality play back. Bluetooth functionality is a recent addition to some amplifiers, allowing you to eliminate the need for wires and direct connection and enjoy the effortless simplicity of high quality wireless Bluetooth playback from a Bluetooth-enabled device.
