Marantz 8802 Vs 8802A As PrePro

I had an 8802A and upgraded to a Lyngdorf M-60.
8802A is great but at this point in the model cycle, I'd probably move up to the 8805 as another poster suggested.

The 7700 series is also worth taking a look at.  I went from an AV8801 to the AV7704 when I got my 4K TV and there was no noticeable difference in sound quality or picture quality and the AV7704 has all the connections I need.

If you're open to refurbished, I'd recommend taking a look at accessories4less.  You can get either the 7705 or 8805 with a 3 year warranty for way below retail price for a new one.

You want the 8802A to support 4K UHD.
