Yeh ok i know its sounds like a stupid question (grottyash), but it sounds ok in both , and i thought hight output mc were designed for that exast reason. I was just looking for a definative answer .
But then again i must remember were i am
You are exactly right. I know people do sometimes use the MC input for high output phono stages, but you shouldn't, as it can cause distortion, particularly if you start ramping up the volume.
Generally, I wouldn't do it and stick with the MM input. It's true it may give you an imbalance in volume compared to other components such as CD, but the circuitry is designed for higher output, whereas that for MC is not.
