My IN100 from Atoll it's working very well with 8 ohm speakers. I'm very satisfied , It's a great amp for hi's money . It haz a good midrange, very clean and detailed and very realistic and neutral. The highs are also very clean and realistic. On the bass it's good too with a tide and defined bass. Now I have thre pairs of speakers: M5 from Epos, Evolution 3 from Visonik (German company) and a pair of ELS 3 from Epos too in bedroom.I've got cables from Symphonic Line (harmonie, the basic and chipest one). I still haven't got a CD-player but I think to a Jadis ( expensive but good!).
