Cambridge 840C or Rega Apollo CD Player?

I have the Cambridge 640C, which does not offer the upsampling feature included with the 840C, but I must say it is superlative with better quality CDs. It uses dual 24-bit Wolfson DACs, and I have compared it to the Rega Planet and Apollo, and the Cambridge sound is more pleasing to me; crisp with good bass response, without being too "bright". I run it through a Threshold amp into Meadowlark Shearwater "Hotrods", and I couldn't be happier. -David
