Some preamps (Atma-sphere & Sonic Frontiers to name a few) have phase inverter switches to let you A/B the sound. This is a really nice feature. Happy Tunes!
Question about polarity-inverting preamps
You will see that I am technically challenged...
Many tube preamps invert polarity. Why don't (or why can't) the designers simply reverse the leads at the out jacks to make the polarity correct? Then we wouldn't have to reverse them ourselves at the amplifier or speaker.
