Hi. I just bought 2nd hand for 300€ a Cambridge Azur 651A amp (condition excellent) and Azur 551P phono stage. My LP`s sound wonderful. The same seller also has the matching CD player (651C) for 350€, also in excellent condition, and of course, they look great together. Would I notice an improvement over my Denon 1930 which is essentially a DVD player which plays CD`s? As I have been collecting since the 70`s, CD`s of course later, I shall continue to use them. About 1000 CD`s and 500LP`s. And finally, how do these new streamers compare on quality?? At the moment in my town somebody is selling for 200€ a Cambridge Audio NP 30. Not quite sure if it`s simply plug in and play? Anything more complicated and I`m, well, you know!! My speakers are B&W XT4 and Transcriptors Hydraulic Reference with Ortofon VMS 20e MkII cartridge. Many thanks.
