If you mean Sony STR-VA555ES it is hard to find, more stock is coming in to Sony end of September ( they say ).
You may find Sony STR-VA333ES is easier to locate, it seems almost the same specification, except for an extra rear speaker channel output , two 7.1 inputs not one 5.1 input, but has one subwoofer out instead of two, hasn't the 2nd room outputs and also the 333 has four fewer Sound Field Programs ( so what ? ) and a different remote.
Whether it is the same as the Sony STR-VA555ES in audio quality is another question, it weighs the same 21kg so isn't a lightweight as 1080 vs 1070. Sony has a track record of releasing inferior updated models so possibly a 333 may not impress Nic Rhodes as 555 did ?
If you mean older STR-V555ES as far as I know they are drying up in Richer Sounds but it's nothing like the VA555ES.
