No sorry that is not possible - it would be using very little power though as it is sitting at idle.
Looking at the specs for the
cubed series -
B135³ integrated amp listed at ≤ 70W at idle
2.5B³ power amp listed at ≤ 40W at idle
- I would think that the power amp section may be consuming ~ 40W at idle above what would be the idle power consumption of the stand-alone BP17³ preamplifier? (specs not yet available for BP17³ preamplifier)
