hi the Marantz NR series is excellent. the power output is 50W RMS into 8 ohms but dont let that put u off. it goes loud. u cant really tell the difference between 50 W and 100 W.. the sound is excellent and it has all the features u can possibly want. I have heard them and they sing..if u dont want to buy new look for a used onkyo or denon. These cme around 15-20K dpending on age.the older machines are solid performers and can be repaired unlike the newer ones.and they sound great.
