General description
The Accuphase A-48S is a Class A stereo power amplifier that excels in sound reproduction and dynamics. With an output of 50 watts per channel into 8 ohms, the A-48S delivers a rich and detailed soundstage, even at low volumes. Thanks to its six-channel parallel push-pull configuration with MOSFETs, this amplifier maintains control over the speakers, resulting in a precise stereo image and impressive dynamics.
The A-48S is designed to drive a wide range of speakers, with linear power output up to 400 watts at 1 ohm. This ensures consistent and stable sound reproduction, regardless of the load. The high damping factor of 1000 contributes to tight and controlled bass reproduction, while the advanced circuitry ensures minimal distortion and maximum detail.
Would you like to experience the Accuphase A-48S for yourself? Schedule a listening session to discover its exceptional sound quality, or contact us to discuss trade-in options.

Background information
The Accuphase A-48S embodies the essence of Accuphase’s philosophy: uncompromising sound quality through innovative engineering. Designed by top engineers in Japan, it utilizes high-quality materials such as specially selected transistors and capacitors to minimize distortion. The internal wiring is meticulously crafted using premium copper, and the chassis is made of reinforced aluminum for optimal rigidity. This craftsmanship and attention to detail are hallmarks of Accuphase’s quality standards.
Brand history
Accuphase was founded in Tokyo in 1972 as Kensonic Laboratory by brothers Nakaichi and Jiro Kasuga. The company name changed to Accuphase Laboratory, Inc. in 1982 to unify the brand name and company name. The brand introduced its first products, the preamplifier C-200, the power amplifier P-300 and the tuner T-100, in 1973. These models were produced with high-quality components and sophisticated workmanship, and immediately received positive reactions and awards. Since 1973, Accuphase has operated from Yokohama, Japan, where its headquarters are located and the brand has expanded its product line to include various audio devices.

Reviews & awards | Accuphase A-48S

Hi-Fi i Muzyka

emphasizes that the Accuphase A-48S is capable of easily delivering sufficient power in a home listening environment, even for those who enjoy higher volumes. The bass response is described as deep, smooth, and resilient, with an emphasis on musicality over strict control. Although the microdynamics are impressive, the macrodynamics may be perceived as slightly subdued when listening to genres such as heavy metal. This underscores the distinctive character of Class A amplifiers, which prioritize refinement and detail.

Hifiverse

emphasizes that the Accuphase A-48S is an amplifier that utilizes a current-feedback amplification topology and a powerful power supply, resulting in ample headroom and stable output in pure Class A. At an 8-ohm load, the amplifier delivers 50 watts, and when the load impedance is halved, the output power doubles. In the event of a brief drop in load impedance to 1 ohm, the amplifier is capable of delivering 400 watts of power.

High Fidelity NEWS

emphasizes that the Accuphase A-48S is the successor to the A-48 and that, although the name change seems subtle, its design is virtually identical to that of the A-48. The amplifier operates in Class A with current feedback and balanced signal detection, and utilizes topologies such as the instrumentation amplifier and the MCS+ circuit. It also features comprehensive protection circuits against overload and short circuits. A glance at the specifications, however, suggests that this is more than just a simple facelift.

hxosplus

emphasizes that the Accuphase A-48S is a high-end Class A power amplifier, representing the manufacturer’s fifth generation, with increased power and improved driving capability. The amplifier delivers 50 W at 8Ω, 100 W at 4Ω, 200 W at 2Ω, and 400 W at 1Ω. It utilizes 6 parallel push-pull MOS-FETs and incorporates technologies such as the Current Feedback Amplification Topology and MCS+ Circuitry for improved performance and stability. In addition, it features a large toroidal transformer and 68,000 μF filter capacitors, and includes protection circuits with MOS-FET switches to prevent short circuits. The amplifier has two pairs of speaker terminals and both XLR and RCA inputs. Its dimensions are 465x211x464 mm, and it weighs 34.8 kg.

CD

De Compact Disc (CD) kwam zoals de meeste uitvindingen niet uit de lucht vallen. Na de uitvinding van de laser in 1958 werd in 1961 het eerste octrooi voor optisch leesbare schijven ingediend. In 1972 werden de eerste digitale videoplaten geïntroduceerd. Na een flop van Philips kwam de fabrikant in 1979 samen met Sony met de eerste cd, wat erop stond weten wij niet maar in 1982 kwam de eerste cd voor de markt uit, het was het album Visitors van ABBA. In dit jaar kwam de eerste speler beschikbaar en zo begon de verdrijving van de lp uit de markt. Velen hebben hun lp’s letterlijk bij het vuil gezet… sommige bezoekers zien wij nog steeds balen als ze dit vertellen. Heb je cd’s, geniet er vooral nog eens van, ze hebben immers geen oneindige levensduur.

CD

The Compact Disc (CD), like most inventions, did not appear out of thin air. After the invention of the laser in 1958, the first patent for optically readable disks was filed in 1961. The first digital video records were introduced in 1972. After a flop by Philips, the manufacturer, together with Sony, released the first CD in 1979. We do not know what it contained, but in 1982 the first CD was released for the market, it was the album Visitors by ABBA. In this year the first player became available and so began the elimination of the LP from the market. Many have literally thrown their LPs in the trash… we still see some visitors being disappointed when they tell us this. Velen hebben hun lp’s letterlijk bij het vuil gezet… sommige bezoekers zien wij nog steeds balen als ze dit vertellen.
