Matching octave with audio physics codex speaker

Thank you for your response mk

This quote from the SoundStage Ultra review of the Codex may be germane.

"With the Audio Physic Codex, I found that the volume setting needed to be a bit higher before I could hear the frequencies at or near its specified lower limit of 28Hz. In fact, it wasn’t until I’d turned up the P-8’s volume to 35% that the Codexes began to sound properly balanced -- which surprised me, considering that this speaker’s claimed sensitivity is 89dB."

It seems you need to crank the volume a bit with these speakers but on paper 130 tube watts would seem to be a good match.

As an ex Octave V70se/V110 owner I have to highly recommend the super black box with those speakers. It lowers the noise floor and gives a hair more headroom.
