Many Thanks folks for your interest and replies. With respect however I think that you might be missing my point a little bit. My issue is that I am more than happy with the sound I get from my analogue front end so, as I see it (but will be corrected) there is no point in thinking about upgrading amp or speakers. I accept that doing this would likely give me an overall improvement but the performance gap between Vinyl and CDP would still be there. Anyway, to give you a bit more info for you to comment on my system is as follows:- Rega Planar 3 with Denon DL160 Cartridge. Marantz CD17 KI Sig CDP with Van Den Hul D102 Mk3 interconnects feeding - Unison Research 'Unico' Amp Gale XL315 speaker cable Castle Avon Speakers. I am using just standard Mains supply and cables as I live in (I think) a relatively 'clean' Mains area, ie well out in the countryside. I did audition one or two Mains cables at home a while ago and failed to be excited by them. Yes, I would be prepared to go for a separate DAC if you feel strongly this is my best option - any suggestions on what make/model ??. I note that 'The Record Spot' suggests valve based CD players. What are the strengths and weakness's of these ?. Compared to vinyl I would say that my Marantz sounds closed-in, hard and 'glassy'. It also has a less firm and tuneful bass and generally less attack. In summary, when I go to listen to vinyl after CD it's like someone has removed a thick blanket from front of speakers. Majority of music listened to is Soft Rock and Blues with a bit of Folk mixed in for a change. Very interested to hear what you all think. Lydeard
