I wish I could compare the different brands but I own the Octave V70SE. Great build quality with some great features. Easy biasing - soft start which helps extends tube life and a protection circuit that really works (Yes I've had a couple of tubes go bad). I might add that the black box option lowers the noise floor and allows for greater dynamics. Also with the V70SE you have a choice of KT88 6550 and EL34. I have all 3 and the EL34 doesn't have as much power but a magical mid range. BTW I'm using mine to drive Dyn C1's which are 85db/1 watt
That being said it would be ideal, if possible to demo them yourself so you can compare sound and features.
Good luck and happy holidays
