Arcam alpha 4 review
Arcam Alpha 1 Integrated Amplifier. Review at a Glance Sound Gentle sound that makes up for what it lacks in bass power and overall incisiveness with an amiable character. Features Bass and treble controls that can be switched out of the signal path; preamp-out jacks for adding a separate amplifier or bi-amping; good-sounding headphone jack. Use Some may find the Alpha under-powered, in which case adding an Arcam amp is an easy solution. Although the company makes separates -- a remote-controlled preamp, three power amps and even two different tuners -- it is their integrated amps and CD players that have brought them the most honor.

Review: Arcam Alpha 5 integrated amplifier
There are now two system of high fidelity, monophonic monaural and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.
Scott ' Posta un commento. Pagine Home New Classic Disclaimer. What is stereo? Arcam Alpha 2 amplifier. The improvements that have been taking place in turntables, CD players, and loudspeakers demand a new level of performance from the amplifier - the heart of every hi-fi system. The discerning buyer expects that today's amplifier should combine a natural yet dynamic and powerful sound quality with good looks and ease of operation.
Until now, only a handful of designs were able to meet all of these stringent criteria. Unfortunately the prices of amplifiers in this select group often made them incceassible to those on a limited budget.
Arcam, recognising this unfulfilled demand, has now designed and produced a modern, top quality amplifier that is truly affordable - the Arcam Alpha 2.
Offering many of the sonic benefits of more expensive models, the Arcam Alpha 2 would be regarded as a fine amplifier at any price. However, when its outstanding performance, facilities and construction are compared with other amplifiers at its price level, it is clear that the Alpha 2 is destined to become a classic, setting the new standards by which all others will be judged.
The Arcam Alpha 2 is a product of Arcam's many years of experience in amplifier design and manufacture.
Detailed theoretical analysis and extensive listening have produced a design that is technically outstanding. This design has been realised in practice using high quality components selected for optimum electrical and sonic performance. The result is an amplifier that maintains the full dynamics of a musical performance while reproducing the subtleties and emotion both accurately and naturally.
Not only does the Alpha 2 produce a generous 30 watts continuous output per channel into 8 ohms, but its special high peak current output stage will drive loudspeakers whose impedance dips as low as 2 ohms. Unlike many other amplifiers the Alpha 2 can be run continuously at high levels because its coolrunning aluminium chassis will not overheat. As well as working properly with all commonly available loudspeakers, the Arcam Aplha 2 is fully compatible with a wide variety of programme sources.
Five inputs are available; four are selected by a rotaty switch and the fifth by the nearby tape monitor button. The Alpha 2's cartridge input is specialy optimised for use with any moving magnet cartridge or high output moving coil cartridge. The highest quality low output moving coil cartridges can also be accommodated using our optional plug in MCA pre-pre-amplifier board. There is a dedicated input for a CD player, further inputs for a Tuner and Video playback and finally a set of line level input and output sockets suitable for use with a tape recorder.
A quality domestic hi-fi amplifier can and should possess those genuinely useful facilities which can improve the performance of the complete system. Typical of Arcam's attention to detail is the Alpha 2' volume control which has been psychoacoustically designed to allow ease of adjustment at the low volume levels often used in the home. These allow precise adjustment of the frequency extremes without coloration of the critical midfrequency band. Used sensibly they can help correct for imperfections elsewhere in the system, particularly those associated with cartridges and loudspeakers.
The constant power law balance control also helps in this respect. The tone and balance controls all have a centre click stop to provide a reference response in the centre position. The Alpha 2 has a front pabel socket which will suit a wide variety of stereo headphones. The headphones and loudspeakers will normally work together as the main loudspeaker sockets are wired directly to the amplifier's output to obtainthe best possible sound quality.
However a second pair of loudspeaker socket is also fitted enabling the loudspeakers to be muted automatically whenever headphones are plugged in. Electronic Design. This ensures a clean, accurate sound. Uniguely the Alpha2 is also configurated to accept out plug in moving coil cartridge pre-pre-amplifier board, the MCA. The MCA and Alpha 2 combination has a much lower noise level and correspondingly greater fidelity than other similarly priced amplifiers.
This allows the Alpha 2 to be used successfully with some of the world's finest MC cartridges. All other inputs are fed directly to the Alpha 2's volume control to ensure a virtually infinite overload margin. The preamplifier stages which follow the volume control again employ low noise professional quality ICs and make minimal use of coupling capacitors to avoid degradation of the sudio signal. All preamplifier circuits are powered by two lownoise, low-impedance regulated power supplies.
The Arcam Alpha 2's power amplifier is an advanced bipolar, high slew-rate design with direct coupled fully complementary class AB output stages. Constant bias circuitry for the driver transistors maintains a clean, dynamic output throughout the entire operating range. The amplifier has a very high transient current capability, made possible by use of watt power transistors combined with high value low ESR reservoir capacitors and a generously rated toroidal mains transformer.
Together these permit instantaneous peak output levels of some watts from a single channel into a 2 ohm load. Nevertheless the amplifier is effectively protected against overload. They are connected within the main feedback loop to prevent degradation of the signal. In addition the layout of the PCB has been optimised for such factors as maximum transient power capability and minimum on-board interaction. Finally, the loudspeaker outputs use ultra high quality PCB mounted 4 mm sockets.
These employ silver loaded contacts amd are soldered directly to the PCB to ensure integrity of the signal path. High quality matching plugs are supplied as standard. Output Power:. Overload Margins:. Disc Inputs : 32 dB at 1 kHz. Other Inputs : 50 dB. Frequency Response:.

Review: Arcam Alpha 8 CD-player
The model 6 provides a lustier output than the 5 but still features the same complement of four line, tape and MM disc inputs. Incidentally, this disc stage, which has been upgraded over the Alpha 3 using a new PMI op-amp, can also be bypassed in favour of a fifth auxiliary input for line-only systems. No sooner had the Mahler CD been loaded into the CD player than lamenting horns soared out into the room, creating a marvellous sense of anticipation that was just sustained by the final flourish of the orchestra as a whole. This made the Alpha 6 a whole lot more interesting than many of its rivals but there was always that nagging sensation of not quite letting go, a hint of restraint that prevented its music from exploding into a larger and even bolder acoustic. Yet the Alpha 6 maintained a steady grip through the tricky rock and pop CDs that had flummoxed others In this test. Any restraint in this instance was interpreted by our panel as a little extra smoothness, keeping any hardness or aggression in check without squashing the dynamics en route. There is some slight muting of dynamics via the MM disc input. However, its sweet balance seems perfectly suited to the lush sound of classical woodwind and strings. With these instruments in particular, the Alpha 6 revealed a wealth of gentle detail without sounding sat-upon.

Arcam Alpha 5 Plus CD-player
Arcam Alpha II integrated stereo amplifier in original packing, marked with serial number. Mature and sweet sounding, a boon to any hi-fi separates system. Cash on collection only. Fully working amplifier includes power cable and unit Arcam alpha 8 amplifier.
The lowest-priced item that has been used or worn previously. The item may have some signs of cosmetic wear, but is fully operational and functions as intended. This item may be a display model or store return that has been used. See details for description of any imperfections. The amp was extremely well packed when I received it, not in the original packing this has doubtless been lost along the way in the last 20 years but in bubble wrap and polystyrene.
There are now two system of high fidelity, monophonic monaural and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.
The new model does not differ by appearance and functional possibilities from the old one. The difference is only in the circuit of the clock generator. Significant differences in the sound of Alpha 5 and Alpha 5 Plus allow you to consider the last to be a competent new model.
Surely. I join all of the above. We can talk about this topic. Here, or in the afternoon.
Bravo, this very good phrase will come in handy.
