I've been looking into getting a DAC for my system in order to feed a new PC through it. I've read about devices from the HRT Streamer II through the DacMagic and up to the Arcam rDAC, which would be at the top of my budget. However, I like the Arcam sound, having used their CD70 player for a good few years now led through their A80 amp. What i'm wondering is, given technology having improved over the past few years, would the rDAC make a difference if I fed my CD70 through it as well as the PC? In short, would the rDAC improve my CD playing, or are they equivalent? I know the obvious answer is to go and test one in a store, but for personal reasons that's difficult and I'd rather know if there's a likely improvement before thinking about going out to listen to one. Thanks.
