Which is better.

Looking to replace my Carver TL3200 CD player. The laser pickup is going out and the cost to repair is roughly $200.00. For that money i think it is time to replace it.

I am looking at an NAD C-538, a Marantz C-5005 ( refurbished) or a Marantz C-6006. All are in the $400.00-$500.00 range.
