Inverting and or non inverting amp?

Can anyone tell me if they know if a Musical Fidelity A308cr is an inverting or non inverting amplifier?
Good eye and good advice. I have a tube based preamp (Rogue 99) and just found out that I should have flipped speaker polarity at the speaker ends. (doh!!) Have to be totally honest though, it doesn't sound MUCH different than before. I just wanted to know what amps do invert?
Typically for preamps the number of amplification stages with each inverting the signal determines whether overall it is inverting. Three stages would be inverted. I had a preamp once that had a invert switch. When you pushed it, another tube was in the circuit uninverting the three stage preamp. While there are two and three stage amps, I cannot think of a circuit that would need to have the output inverted.
If you can't tell the difference in sound use a CD with vocals , to hear the difference. If you still can't your speakers aren't setup to image correctly. There are lots of threads on speaker setup to help you out. Also the bass will be kinda sucked out, though keep in mind it is a subtle difference.
Not that simple. Almost half of all vinyl and CDs have the absolute polarity inverted. So you really need a polarity inversion switch on one your components (mine is on the DAC). Some of the labels with reverse polarity are RCA, Mercury Living Presence, MCA, Capital, DG, London and some Sony. So a CD with vocals will not help unless you know the polarity of the CD itself.
Thanks guys for all of the responses. I have a test disc from my car audio days and I can now hear the difference with a track specifically used to judge relative polarity and phasing in and out.
