Adcom GTP-400 Pre-Amp / Processor AM/FM Digital Tuner Excellent Clean Works Flawlessly
The Stereophile review concludes "... the performance offered is simply superb for anything close to this price [at the time, $350 MSRP], and is always in the service of the music. The GTP-400 allows you to enter the realm of high-end audio without spending a high-end fortune. ...The GTP-400 sets a new standard in the cost vs performance category, and you'll have to spend close to $1000 for a separate pre-amp and tuner in order to move to a higher level of perfomance."
