I got a CJ preamp a few months ago. In the manual it clearly describes how it uses an inverted phased amplification. SOOOO you MAY need to reverse your speaker leads for better sound.
Of course I NEVER tried that!!!! Until today. I'm still laughing at how darn good it sounds now that I reversed the speaker leads.
I just love when I find something on my old toys.

At least I did read it. DOING it was another thing! Ok I'm a little lazy and stupid at times.

What am I supposed to hear that is different?
If they're phase-coherent and have minimal or no crossovers, you'll likely hear a difference. Whether you prefer the sound in normal or inverted polarity (phase) position is then up to you. Since there is no uniformity (to put it mildly) in the way stuff is recorded in the first place, you may well decide the hell with it. I wouldn't be without the switch myself, but the hardest-core audiophile I know can't be bothered with it.
Thanks for the info, I really hear no difference myself...

Nutty,
considering that there is NO standard for music recording as to absolute phase.
I've experimented with this when I had an amp with a phase switch and SOME recordings did benefit. But an entire album? Not. And most albums, or single SONGS on an album did not benefit, since no attention was paid to phase of individual tracks. Some tracks might have even been laid down in another CITY.
Somewhere ONLINE is a test you can take. I'd use HEADPHONES or a good set of buds. 50% is 'chance'.
Too much is never enough
Congrats for recognizing the polarity issue.
One of my audio friends played with a Conrad-Johnson Classic (non-SE) preamp. Immediately under the IEC jack is the Classic's fuse holder. I don't know what the fuse's value is, but for relatively little cost, you can change the Classic's sound, by experimenting with after-market fuses.
My friend said that the Hi-Fi Tuning Supreme usefully maintained top end extension, and gave the Classic a better ability to stave off bloated imaging. Moreover, the Supreme is known for lowering the noise floor.
But don't miss out on other after-market fuses, either.

I've had a couple phase inverting pre-amps including a CJ. Always switched the speaker leads as suggested. That said( and already mentioned by another inmate) recordings are all over the board in that respect, so I wouldn't beat myself up over it. I've always felt the only really useful way to sort this out would be to have a phase switch on a remote for example. But this isn't a feature you'll see on the majority of DACs or pre-amps. Bottom line, I'd reverse the leads and continue listening as always.
Although, sometimes I do wish I had a polarity switch. You know, just to see if it really does make a difference sometimes...

I've had my eye on a DAC with a polarity switch for the same reason. With my two way speakers that have the ribbon tweeter crossed over around 10 KHz you can really hear the difference. It does vary between recordings.
I always test phase both ways with new amplification, because IME it makes a huge difference. Now, of course some recordings have mixed phase tracks, but that's another issue...
CJ makes outstanding gear, IME.
because I've owned their equipment for over 20 years.
My DirectStream DAC has a polarity in/out switch on the remote. For whatever reason, I usually cannot tell the difference when switching it on the fly. And yes, my conrad-johnson CA200 integrated/control amplifier does invert phase and I have reversed both speaker cable leads to compensate.
