Hi, I am having Sony SS-VX77 front speakers and SS-RS155V surround speakers. (these are speaker with model Sony MHC-VX55.). Please refer http://pdf.crse.com/manuals/4226942111.pdf for technical specification of the speakers. It would be great if anyone can suggest me a suitable good sound quality amplifier for these speakers, so that I can connect my DVDplayer/DTH's audio ouputs and listen music through these speakers. Also I like to have USB interface(with MP3 player) and FM tuner integrated with the amplifier. Thanks in advance. Regards, Kumar
