hello there, New to this forum and needing some help pretty badly. I`m looking for a new amp or reciever to replace my ancient pro-logic Yammy. I am considering various brands, at present mostly Marantz and Yamaha. Music reproduct i.e 2 channel stereo is no issue to me at all since I already have a very good power amp a vintage valve as it happens. So with this is mind how does say the Marantz SR5400 fare with the Yamaha DSPAX-640SE? (I did write RXV originally!) All I am thinking about it home cinema performance where reviews always consider music too. All comments would be most appreciated.
