Octave v70se OR v80se

No I don't. I think another thing that has to brought up is the protection the Octave has to offer and soft start circuitry. It's second to none IMO. I had a few tubes 'arc over' and NO damage to any circuitry. Biasing tubes is very easy too. If I had a complaint regarding the V70se or V110 is swapping out the 'little' tubes. Hard to get a hold of. Not a problem with the V80. Another feature that could be taken either way was the auto shut down to standby when no music is present for about 10 min.

Both the V70se and V80se are excellent IA's. I used to own a V70se and later the V110 with the black box. I also had Dyn C1's and later the Signatures. I had an in-home demo of the V40se for a week. As you move up the line there is a bit more control in the music. IMO the black box or super black box is a must. Lowers the noise floor quite a bit and provides a touch more headroom. I have not heard the V80se only the V80. I got out of tubes just before the V80se came out. The V80 had better transformers. One nice thing about the V110 is it has a switch on the back to change the plate voltage down to accommodate tubes like EL34's 6550's and KT88's that way you are not limited to KT120's. Honestly I hated the KT120's. I'm guessing the V80se also has it so your not limited to KT120/150. I did find Ei KT90's worked great and sounded better at the higher plate voltage.
Per Andreas the super black box was designed for speakers with multiple drivers. I never tried the SBB with my C1's but my friend with the a V80 - BB and Dyn Sapphires demoed a SBB. the difference was IMO was huge. So I can't say what gain would be had with the C20's.

@david_ten I would say the V80se would out perform the V70se with the SBB.

The beauty of tubes is if you ever want to change up the sound signature just swap out some tubes instead of buying a new amp. When I had the C1's I rolled many different tubes and found the original Tung Sol 6550 black plates sounded the absolute best to me and my dealer. BUT when I decided to upgrade my Dyn C1's for Raidho D1's I hated the the TS 6550 bp's. I liked the Ei KT90's much better with the D1's. Now with the Dyn's the V70se or the V110 never ran out of 'steam' when pushed extremely hard. But with the Raidho's they would only when pushed hard. Maybe the SBB would have helped.


So I would go with the V80se and consider a BB at a later time.

Dan those prices may be euro's. Right before I traded in my V110 Octave dropped its pricing about 1000 to reflect the drop in the euro. So add approx 1.18% for USD
I did find this with Google but I don't see a datehttp://www.music2.nl/octave-audio-tube-amps/pricelist-octave/

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.

Congrats Dan - Did the V110 have the KT120's. I thought the V110 was punchy boomy and not as refined. But like I had mentioned the KT120's were the culprit. By the time I got it I already had many different output tubes. Which tubes came with the V70se. Mine came with the SED 6550's and later purchased some SED KT88's. SED is no longer in production. The SED KT88 is a warmer sound and the 6550 is more linear. That said I have GEC KT88's that are very linear where the original TS 6550bp is much warmer. Guess what I am saying tubes from different manufacturers sound very different.Again Congrats
