Octave Audio integrated amplifiers

Hello All.,
Thanks for your suggestion and Please recommend me the best tube for v-70se? Becoz I am not tube guy also no knowledge on that lines.

Rabbani - Best tube?? Which tube?? Input (12ax7 qty 1) - Driver/inverters (12at7 qty 2)- Output (qty 4). Any or all tubes will make a difference in sound. Which tubes are in yours? Are you to wanting to change the sound? If so in what way.

My V70SE came with SED KT88's for outputs and all SED input and driver tubes. Others I've seen had Sovtek 12ax7lps for an input and Rca 12at7wa's for driver/inverters. Even though I'm no big fan of the Tung Sol KT120 you might be. For me I found I need to change both the input and drivers to make the KT120's sound pretty good. I like the Rca 5751 (lower gain) triple mica black plate for an input or a Telefunken 12ax7. But for drivers I like the Mullard CV4024 or the Telefunken 5965 (12at7 long ribbed plates not short plates) for the KT120's. Again I found the KT120 to be a bit on the forward/bright side and changing those 'little' helped tame the sound for my tastes.

BTW Andreas Hoffman (owner and designer of Octave) states the KT120 works fine in the V70SE.

Forgot to mention I own quite a few tubes Like the original Tung Sol solid black and grey plates (my favorite) SED EL34 - 6550 - KT88's - Gold Lion KT88 re-issue - Ei KT90 type2 and 3 - KR Audio branded Tesla KT88's - Gec/MO KT88's and EAT KT88's along with some 'little' tubes.

I would steer clear of the Tesla and Eat tubes. I have heard those work most reliably with a 450 plate voltage where the V70 has a 540 plate voltage. I did hear that after losing 4 out of 7 EAT's and 1 Tesla.

I have a V70 SE with black box using KT88 Gold Lion re-issue power tubes. I run it into Dynaudio Confidence C1 (original mk1). I use a Meitner MA-1 DAC or a modded EAR 834p as source. Speaker cables and XLR interconnects from DAC are both Nordost Tyr (mk1) while Luminous Audio Silver Reference from the EAR. I'm extremely happy with my setup. When moving to a larger space, I am considering Dyn Confidence C2 MKII or Signatures and will use same amp. I hardly ever turn the volume knob past 9 o'clock.

Xti16, To be frank I have used only SS amps all my time also no knowledge in tubes. Please suggest me below...
-Input suggested tubes & co (stack unit comes with what tube?)
-Driver suggested tubes& co (stack unit comes with what tube?)
-Output suggested tubes& co (stack unit comes with what tube?)
I know the tubes selection depended on own taste but here in my region not easy to try diff. tubes. Hence, I need to purchase the unit with right tubes form dealer. Thanks in advance your feedback.
