Yba amp and Classe pre-am ?

Hello, I have Classe SSP25 and I would like to buy a YBA amp for the music because I hear that YBA and Jm lab is a good combo. I already tried the Classe amp and it's very good but my friends told me that YBA is much much better. BTW, I've read all the people's reviews and all of them using YBA amp and pre-amp with Jm lab. So, what do you think? Should I buy the Classe amp or Yba amp? Please give me your inputs. The reason I picked the SSP25 pre-amp because I also want hometheater Thank you very much DT
