ESRI ArcView to check the values). Perhaps my problem is really not

My first transformation is below:
C:\proj4>cs2cs +proj=latlong +ellps=GRS80 +to +proj=utm +zone=11
790277.46 5694492.75 0.000

Type: Zone 11
Projection: Transverse Mercator
Central Meridian: -117
Ref Lat: 0
Scale factor: 0.9996
False E: 500000
False N: 0
And get - 790298,5694496.266518
You can see it is close but not quite on. Any suggestions would be most
