Inverted phase preamps?

Blue Circle BC21.1 inverts and Gilbert said to reverse the cables at either end since this accomplishes the same thing.

The Wood Effect by Clark Johnsen may illuminate this discussion/query. Clark writes w/ uncanny skill for Positive Feedback. May the audio nervosa continue unabated!

Since 50% of all recordings are phase-inverted, and from one to the next you can't tell except by playing, I would say it does not really matter!!!!!

So just mark on the record sleeve or CD case whether the recording is in phase or out of phase. It does matter! And I don't buy the idea of reversing speaker cables, as not only does it cause undue wear and tear on the connectors, it is too easy to short something out. The only sensible, convenient solution is a phase switch on the preamp or source component.

Amp end or speaker end - it makes no difference.

Lots of recordings are made out of phase and you can hear it. I got some new Cream remasters which have songs out of phase and I'll play with some switching later tonight.
