I hated the day I gave up my old Marantz amplifier/tuner. It was a great piece of equipment. But, alas, it was obsolete. It didn't have a single digital bone in it's body...not a single digital input. The new set top boxes (cable/satellite) and Blu-Ray DVD players all had optical digital outputs that needed a corresponding input for sound.
So, I now have a Onkyo TX-SR501 AV Receiver. It's not nearly the machine the Marantz was and didn't cost nearly as much, but it's a great piece of equipment.
They are hard to find now...have been replaced by newer, probably better, models, but they are great! Used ones are about $50 at Amazon.
