ELITE model years?

[TBoneSTL]

I was a little confused with all the models, what are the model years of these models: VSX-52tx, 53tx, 54tx, 55txi, 56txi. Are some 04 and some 05, or older, or are they all the same model year? Thanks in advance!

the 53tx and 55txi are '04 models, the rest are '05 models.
