Adcom GTP-350


The true triumph of Adcom's design and production techniques lies in the radical improvement that has been brought to sensibly priced components. Although the GTP-350 Stereo Tuner/Preamplifier is Adcom's most affordable, it has much in common with its more costly counterparts.

Both engineers and audiophiles acknowledge the superiority of Class A biased linear amplifiers. But it took Adcom to bring this enhancement to an affordable price range. Proprietary Adcom circuit topology affords the listener the stability, headroom, tonal balance, superior resolution and accurate spatiality once reserved for the world's very best (and most expensive) components. At other critical circuit points, discrete components are used in place of generic, off the shelf ICs.

The tuner section strikes the perfect balance between sonic performance and ease of use. The quartz-referenced, digitally synthesized tuning system achieves tuning accuracy of 99.99% locking the station instantaneously without drift or signal error. Sound quality has been optimized by preventing digital control pulses from bleeding into the very sensitive sections of the tuner's front end. This virtually eliminates the synthesizer noise, distortion and phase shift all too common in other designs.

The GTP-350 interfaces perfectly with all of Adcom's legendary power amplifiers, so you need only invest in the amount of power your loudspeakers and environment dictate. Seldom have both sonic performance and value been so well served by audio technology.
