I have used an Adcom GTP 500 II for the past 13 years, that is just now requiring some servicing (power switch relay needs replacing). I always thought that it was a smart way to combine components and share a power supply ... as they are not in the same physical unit as the power amp. The Adcom's tuner performed well, as long as it had a good antenna. FM was highly listenable and the preamp married well with the Adcom 545 power amp, that I used. Another clever combination is the Musical Fidelity preamp/ cd player, given how a good deal of listeners do not care about FM anymore.
