Octave v70se OR v80se


Hello Everyone!
I recently bought the amazing Dynaudio Contour 20 speakers and am about to purchase the Octave int amp. I have listened to the v70se but have also heard great things about the v80se model (have not heard v80se in person). So far this is the best integrated amp I have heard in this price range!

My question is should I get the v70se WITH a black box and call it a day OR just get the v80se? The price difference between v70se and v80se is pretty significant.

I have a 20x25 foot room and I listen to all kinds of music. Any suggestions?

Thanks in advance!

Thanks!
The unit has not arrived yet and once I get v70se settled in I'll post my feedback.

xti16 I think they were kt120 but I'm not too sureĀ 
The KT120's were standard with the V110 when I got mine. Higher plate voltage and higher grid voltages made the for extra 40W. Other than that it was made off the V70se chassis with a switch to select the higher voltages.
Thanks! for the update -danimaz

what other gear is in your system?
Happy Listening!
