Often overlooked, the humble power amplifier has an
enormous job to do within a modern hifi or AV system. With over 30 years of
audiophile engineering experience, Arcam is one of the UK’s most respected
audio companies with unique skills in power amplifier design. The new P38
stereo stereo power amplifier is the latest in a long family line of award
winning HiFi amplifiers and is the perfect match for the A38 in bi-amplified
systems or the C31 pre-amplifier in a pre/power combination.
The A38/P38 design team was given a simple goal; to
develop the best performing stereo amplifiers Arcam had ever produced.
Although a huge task, the team dug deep into the basic structure of amplifier
design and the result was a remarkable improvement in fidelity.
An in-house research project yielded a wealth of
information concerning the influences of thermal conditions on power amplifier
performance. As a result the P38 features a number of new technologies which
practically eliminate thermal modulation of audio signals and ensure truly
dynamic and enthralling reproduction. New Sanken output devices and
dramatically improved thermal coupling provide an extremely stable device
temperature resulting in much improved linearity.
The massive torroid based power supply delivers
effortless power with a new low noise topology improving transient response.
The ultra-wide band design of the P38 offers an
extended frequency response that is perfectly suited to the demanding
requirements of high resolution audio formats. High resolution formats such as
SACD, DVD-Audio and new surround codecs like Dolby Digital+ and DTS-HD can
deliver much wider frequency and dynamic ranges. The P38 delivers the full
potential of these new formats with control and finesse..
