Hey! I'm an octave user as well but only the HP500se pre, although i've i have heard quite a few octave amps on various setups.
I think XTi16 has summed it up very well.
They first question you have to ask yourself here is are you happy with the V70se with 6550 tubes in your set up? do feel the need for more power or a different tonal signature?
If not then get it with a SBB straight away, but it you feel that it's not floating your boat then the choice of V80se is more obvious,which in my opinion is a better amp. The SBB can always be purchased latter.
Hope it helps.
All the best
Cheers
