i bought my entry level Hi Fi system some years ago,one recommended at the time by What HiFi sound and Vision.Marantz C.D.6000,C.D. player,Marantz PM60100SE amplifier,and Tannoy R1 Speakers.I added Atacam stands and Van Den Hul intoconnects.Iam retired and cannot afford to upgrade,i am not interested in Computer Streaming,MP3 and M.P.3 Docks,all i wish to do is buy a C.D. and sit and listen.I have read of D.A.C. and would like to ask if a £40 Lindy D.A.C. adde to my system would improve the sound.I would also like to know if a present today entry level system such as Marantz CD6003 C.D. player,Marantz PM6003 amplifier +Mission MX1 Speakers would give me better sound than my getting on a bit system.
