PMC Fact 3 with hegel h160 or accuphase 350

I don't know what other brands you have access to.  There are several other solid-state integrated's that are a little more "forgiving" than the Hegel, Luxman, Ayre, even Simaudio (in my experience).  PMC's Fact series is also less forgiving than their Twenty and now Twenty5 lines.  Otherwise, as already mentioned, start looking at tubes.

I often read that  the pmc need a lot of power for to play well
100watt could be enought???

Although I haven't heard it I'm sure the Accuphase would be great and unless your room is huge and open 100 quality watts should be fine.

Two other amps to consider would the Marantz PM11S3 and the Yamaha A-S2100. They, along with the Accuphase have a reputation of being a bit warmer and smoother with a big full sound. Musical Fidelity also has a fuller warmer signature. Good luck.

Cheers,

You wouldn't be asking this question had you heard the Accuphase. I would suggest making that happen. Hegel is nice gear but the Accuphase is in a totally different league. (I owned the H200 and now own Accuphase E600).
