The 777ES is a classic, and only one notch below the SCD-1. You're unlikely to find anything better than the 777ES for a grand.
I'd consider having your 777ES modded by Reference Audio Mods (RAM). If you RAM exactly what sound you're looking for in a new player, they would be able to suggest the best use of $1000.
Otherwise, consider a DAC and use the 777ES as a transport. There are many excellent used DACs available for ~$1000.
