To the TS:
Always a good place to start is a Marantz or a Philips CD player. I highly recommend the Marantz CD-63SE MKII, which is a very musically sounding player. You can pop-in any kind of music and it will play well. Furthermore, service parts and components are widely available if repair is need. Ideally, the 'entire' CD player should be separated into a two components- a transport and a DAC (Digital-to-Analog Converter). There are brands like Meridan, Musical Fidelity, Linn, Primare and Estoric that sell the transport and DAC separately.
For pre and power amps, Rotel is makes wonderful budget systems. If you want a slighter higher-end pre-power amp, try Aragon, Carver or Adcom. For an integrated amp, try Exposure or Audiolab (many people find Audiolabs bright and metallic sounding, but it is probably the most neutral and revealing integrated amp I have listened to so far... at least to my ears it does).
Choice of speakers depend on your listening habits and where they are to be placed. If you stay in a HDB flat or a smaller condominium unit, and the speakers are to be placed in your bedroom. Your choice is pretty much limited to bookshelf speakers. Mission, Monitor Audio and KEF makes some of the better sounding and versatile bookshelf units. For higher-end speakers, try Epos, ProAc, or Sonus Faber.
And if you intend to place your system in your living room or an area with larger floor space, I suggest you listen to B&W, Infinity or Paradigm. For higher-end units, try those from Martin Logan, Vandersteen or Thiel.
Keep in mind that that Hi-Fi 'siao' (the Hong Kongers termed it "Fatt Siew" or "Fever" in Cantonese) is more costly than photo 'siao', so you may want to take it step-by-step. A good pair of interconnects cable can cost as much as a prime lens. Similarly, a good pair of speakers cost more than a Canon EOS 1Ds MkIII with a 50mm f1.2.
For an audiophile, a good Hi-Fi 'system' consists of not only the electronics, but the entire listening area as well. A well setup 'system' can costs more than S$1M for some.
A word of advice. Never, never, never doubles a DVD player as a CD player, unless you use it solely as a CD transport.
