I'm looking for a new hifi to replace my Cambridge A1 mk3/DAB300 combo. It's a little bit too bulky but I could live with that if it came with a remote. I'm looking at the second hand market to try and get the most for my money. I had intended on getting a mini hi fi system for size reasons, something like Onkyo CR515DAB, Yamaha CRX-M170, or Teac/Denon equivalents. But I've read separates will give significantly better sound quality, so if that's true I could deal with the larger size (would just mean moving my PS3 somewhere else). Really don't want to spend more than £100, less if I can help it. Can anyone offer advise about what I could look at if separates would give me significantly better sound? Finding it really hard to search for anything relevant on eBay. If there wouldn't be a significant difference then recommendations on which mini hi fi to focus on would help too. Whatever I buy will be paired with Tannoy Mercury V1s if that makes any difference.
