Rogue preamp owners - inverted polarity, do you???

I just received my Rogue 66 preamp back from Mark with the Magnum upgrade. Prior I had been running it without the polarity inverted as suggested by the owners manual (who reads those things anyways...unless there's a problem). I decided to try it the "factory" way and invert my speaker cable leads and found there was a difference but I am not sure if its a difference for the better. I find the sound smoother (maybe a little less detail) and the soundstage seems compressed somewhat in terms of width. Now how much of the difference is attributed to the inversion or the Magnum upgrade (obviously the new linestage tubes play a big part) is impossible to determine at this point...

For you owners of Rogue preamps - do you invert or not???

Either way is fine (polarity wise). I would follow Rogue's recommendation. Polarity inversion is dismissed by as many as it is believed. Some preamps offer the provision to change polarity at the remote. Expirementing with this reveals very little on most music/recordings,at other times a slight change in midrange tonality.
If your pre was recently upgraded, listen to it for 100-200 hours to let it burn-in. It is my belief that any new parts, wiring etc, needs time to "settle-in". Once your pre has re-settled, take a handful of your favourite recordings and do a listening evaluation with polarity inversion to determine which way sounded the best.
