High End Amplifiers
About AmplifiersThe power amplifier has the challenging task of taking the audio signal that comes in and muscling your speaker into reproducing it at whatever volume your heart desires. Ultimately, it is responsible for making sure that the speaker drivers move about their business as quickly and accurately as possible, all while not introducing any distortion. Whether your cup of tea is solid state or tubes, we have a variety of superb-sounding amplifiers to complement your system.
● Arcam
Arcam makes digital components, preamplifiers, surround sound processors, amplifiers, and tuners.
● Audio Research
For those lucky few for whom price is no object, the REF600 Mk II Mono Reference Power Amplifier is available. It has enough power to drive any conceivable speaker system and is obviously designed and built to an absolutely cost-no-object level. Also, a 300 watt per channel version, the REF300 Mk II (pictured at left) is now available which is a "best buy" in ultra-high end tube amplification—as most systems would never need more power than what this has to offer. Audio Research also makes digital components, preamplifiers, and cables.
● Boulder
Boulder amplifiers have immense power reserves, terrific dynamics, bass power galore―and yet are sweet sounding and delicate. The 300 watt / channel stereo Boulder 1060 is pictured at the left.
● Halcro
● Linn
● Musical Fidelity
The A3.5 integrated amplifier are pictured at the left.
● Nagra
● NAD
NAD has just released the new M2 which will play all PCM sampling rates. Not only does it function as a D-A converter in that it takes in digital signals and outputs analog, but the M2 functions as a complete digital integrated amp and has an analog input as well. NAD makes analog preamps as well as analog power and integrated amps. The NAD M2 is shown on the left.

Soulution
makes digital
components, pre-amplifiers, amplifiers.
A pair of Soulution 700 mono power amplifiers are pictured at the left.
Note: Soulution is a manufacturer that recently started making high end audio electronics and we do not have this new line on display at the store. The reason that we have included this new line in our line listings here is that the Magico Ultimate II speakers are extremely efficient—and at over 110db efficiency it is nice to have the quietest amplifier possible in terms of circuit noise both at system idle and during the quietest passages of music. (Of course this particular aspect is not normally of consideration with the vast majority of speakers which are in the 85-95db efficiency range.) We have heard the Soulution amps on the Magico Ultimate II's and so we know that the amps are a good match for the speakers. If you are interested in knowing more there are links below.

Founded
in 1977, Spectral is one of the most respected names in high end audio today. Spectral
Audio makes
wide bandwidth, extremely fast, high resolution amplifiers. Their
amplifiers use many smaller power supplies, rather than one big
one. This locates a power supply (capacitors, rectifiers,
regulators, and secondary windings) closer to each FET output
device. Spectral amplifiers have a very transparent sound, with
excellent settling (the ability of the amplifier to stop the
speaker after a transient).
Note: Whereas other Spectral Audio components (i.e. their preamplifiers and digital source components) may be used with any other brand of equipment, Spectral mandates that their non-Universal amplifiers be driven by a Spectral preamplifier to ensure reliable operation. Spectral Universal amplifiers however may be driven directly by any brand of preamp, D-A, or surround sound processor. In addition, Spectral amplifiers need to be used in conjunction with the proper Spectral-approved MIT interconnects and speaker cables. These usage guidelines are now a condition of Spectral's warranty on their amplifiers. There are several reasons for these guidelines:
- Because of their wide bandwidth, Spectral amplifiers can amplify high frequency signals in the MHz range at massive power levels. Therefore radio frequency noise must be kept out of the amplifier. The MIT interconnects contain RF protection, and Spectral preamplifiers are stable at these high frequencies.
- Unlike most all solid state preamps, Spectral preamplifiers are true discrete designs, are DC coupled, and can output the high current that the (non-Universal) Spectral power amps are designed to be driven by. Other brands of preamplifiers often use integrated circuits or other devices which will probably not be able to drive the amplifier properly.
- As part of their stability design, Spectral amplifiers use an output network found in the proper MIT speaker cables. (Spectral has found that by placing this network close to the load, i.e. the speaker, they can achieve superior results.)
What will happen if you don't follow these guidelines? Well, it's a probability thing. You may not encounter any problems—or you may encounter premature failure of some components in the amplifier. Or (worst case) your amplifier may suffer severe RF problems, and you will have to pay to have all the output devices replaced (which is expensive). Therefore, we highly recommend that you follow Spectral's warranty and operational guidelines. If you have further questions, please don't hesitate to call us as 781-893-9000.
So why would anybody bother using an amplifier that needs such precise conditions to be operated properly? Because for music lovers who value linearity—i.e. who truly wish to hear what the musicians played in an acoustic space on a recording—Spectral offers an incredibly transparent window on recorded musical events. And for the many satisfied Spectral clients, nothing else meets their demanding criteria for emotional involvement with the music.
Spectral also makes digital components and pre-amplifiers.
