Zonder meer de mooist klinkende tuner die Pioneer ooit heeft gebouwd. Technische staat is 10/10, visueel 9/10. Alleen op één van de houten zijkanten zitten een kleine vlek.
Bij het ontwerp is heel veel aandacht besteed aan details. Uit de folder van Pioneer: "Elite Reference Digital Synthesizer Super Tuner: We`ve pushed the level of FM sound quality to record highs with the addition of two Pioneer exclusives to the F-91. The first is the ARTS (Active Real-Time Tracing System) included in the IF section of the tuner. With some tuners, especially expensive ones, you have the choice of using a narrow or wide IF bandwidth. The first lets you avoid interference, but you have to settle for an increase in distortion. The second provides lower distortion and better sound, but interference may get in the way. Pioneer ARTS - it`s simply the best of both worlds: its IF filter actively follows the desired signal while rejecting interference. Now you can enjoy both the low distortion of a wide bandpass and the high selectivity of a narrow bandpass. Sensitivity is much improved, too. The second Pioneer feature is the Digital Direct Decoder Type III. It takes the output from the ARTS IF circuitry and converts it into digital form before directly turning it into stereo analog signals. Thanks to pure digital operation, our DDD Type III is less prone to signal degradation. Moreover, in the Type III, we`ve simplified the circuitry using a new PLL detector, which has reduced noise even much further. Improvements extend to other circuits of the tuner as well. The front end, for instance, features an ID MOSFET to improve reception. Indeed, the front end is as highly sensitive and selective as an elaborate 4-ganged tuning capacitor. The F-91, like Pioneer amps and CD players, is designed based on our anti-vibration concept to damp harmful resonance and vibration for improved sound. We`ve turned circuits into modules and filled them with epoxy resin. And we`ve added honeycomb ribs to the chassis and used large insulators to shut out external vibration."
