Dazed and Confused - Upgrading System But Too Many Options!


Help! I am upgrading my stereo and just have too many options. Every time I think I have it figured out I go down another rabbit hole. I’ll start by saying what I have.

Speakers: Paradigm Monitor 9
Amp: B&K ST2140
Preamp: Rotel RC980BX
CD: Arcam CD72
Phono: Rega P3

I have settled on the KEF LS-50 monitors. I am looking to add a network media streamer and either a new preamp or integrated amp.

So to keep this short, I see these as my main options:
  • Do I get an integrated amp like Rega Elex-R, Creek Evolution 50A/100A with a Ruby DAC or something else?
  • Do I leave off the Ruby DAC and get a streamer like Cambridge Audio CXN?
  • Do I forget about both of the above and get a Cambridge Azur 851N that is a preamp and solid media streamer?
  • Do I keep my B&K and just get a new preamp and media streamer (leaning toward Cambridge CXN)? I really like the B&K and think it’s very solid but then I would need to get another amp to power the Paradigms in the basement. 
  • Do I say “screw it all” and just get a PS Audio Sprout?

My listening style of late has been headphones on my Android phone but I want to return to where I was BC (before children). The monitor speakers will be better for listening anywhere on the main floor, not just in the sweet spot. I plan to convert my CD collection to FLAC (currently it’s all 320 kbps mp3). So I have some work to do but I need to make it easier for me to listen to music at home and upgrade the quality.

I know I rambled on, so if you made it this far, thanks for reading through.

I think I am asking too many questions.  Let me refine.

Should I keep my B&K ST2140 and spend more on a preamp or should I replace the ST2140 with an Integrated amp?  Either way I'm getting a new preamp. I'm open to used equipment as well as new as long as the used equipment can accept current digital technologies.

Set up your digital front end prior to the other changes. I would go with an external DAC for down the road flexibility. Keep your amp/pre for now.

Have you listened to and are you set on the KEF LS-50s?

When you say "either way I am getting a new preamp" do you mean phonostage? If so that will cover your vinyl needs. Again adding flexibility for down the road.

Take it one step at a time, removing the confusion.

Enjoy the journey!
