Thanks Naturelover.
Actually I downloaded a lossless version of a song of 1979 Tamil film from saregama website. Though I have the same song( since it is my favorite), purchased from iTunes and Nokia Music store( mp3 @256kbps), just to compare this song,yesterday downloaded from saregama site, their lossless version in wav format. When I played this file, I really surprised to hear the diff. in SQ, though it is expected when comparing a wav with aac/mp3. the lossless version has a clear HF as well as LF response with a good soundstage.
As everybody told, I too do not like the SQ of saregama CD which literally equals to a high mp3 file and that is the reason I stopped buying CDs nowadays.
