Reviews: Rolls RS81B Quartz PLL Synthesized AM/FM Tuner
Nice model
Finishing not perfect
High power consumption
Another little point but to be mentioned, the power consumption is high: 45 watts. This is of course not so important for people in pro audio business but Rolls could have done better on this.
Those points behind, the sound quality is astonishingly good, even better than the Yamaha one I have in my Hi-Fi system! very high audio definition, clean reception and for that reason, I will yes recommend this tuner to other potential buyers.
