I'm using a Rega 2k as a transport with an MSB Gold Dac and there is a significant improvement in terms of soundstage, clarity, bass, etc. This is confirmed every now and then when I a/b the Rega vs Rega+MSB. That said there is a disparity in cost between the two and the Rega on its own isn't bad but overall everything is just better with the MSB in the mix.
Adding a DAC to a cdp
I enjoy the stories of transport and dac combos that come real close to sound produced by high end turntables. With over 500 cds I am not about to go to vinyl or even another digital format at this point. I currently have a Rega Planet 2000 cdp - decent but I know not the final word in cd players. I understand that my Planet has a pretty decent DAC built in. I also think that one option I might consider is the addition of an outboard dac between my cd player and amplifier turning the Planet into a Transport. Have read wonderful things about Bel Canto, EVS, Audio Note and too many other great dacs and how they can enhance the cd based listening experience and that the technology is really jumping forward. From your expierience what would I hear if I took this approach.
