Octave v70se OR v80se

Thank you both for your responses. The thing is that I understand that v80se is twice as much in power, and that dynaudio like power... however is the price difference of almost 3500$ worth it or not to go with the v80se. That’s the question I have in mind which I am unable to get an answer to. Would the v80se sound 'significantly' better at 50% or higher volumes when matched with the Countor 20s? May be that 3500$ gap can be filled with a black box? 

Thanks inna.
Usually dealers don't have all the models to compare and that's the case here. The reason I don't want to talk to octave is I want to hear from customers to get their unbiased opinion. But u do have a point. It is subjective !

@willemj
'It will sound cleaner because of hefty power output' 'Yamaha'? Your kidding right? 

Thanks everyone.
I have decided to go with the Octave v70se!
V80se is an excellent unit no doubt but reality is that it is out of my range or else I would have gone with it.

Why no v110se? Two reasons:

1. I heard the V110 (non SE version) and I did not like it as much as the v70se. It was punchy and felt powerful but it was a bit boomy and not as refined as the v70se. I have not heard the v110se btw... but heard the v110 (non SE version) and it sounded a bit too boomy and not as refined as the v70SE. PLUS it is also out of my range!

To my ears v70se and the tubes it comes it are an excellent match for the c20s!

One more thing:
I heard the Pass Labs INT - 60 with my c20s! It is a very good amplifier. A bit more on the relaxed side of the spectrum. Or may be I am not a huge fan of warm laid back sound. I don’t know what it is. To me it did not sound anything like a $9,000 amp. However the Octave v80SE DID :-)...

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 sure
