I went with the MSB Link DAC III with the P1000 power base. The Marantz CD67SE is basically built well. I would suggest getting a good digital cable to hookup between the D/A converter and the CD player. The MSB sound good out of the box, but it sounds alot better after about 100 hours of play time. You can look at specs and reviews at www.msbtech.com. I purchased mine from www.amusicdirect.com out of Chicago.
CDP upgrade
I am considering up grading my cd-player. Right now I have a Marantz 67se. I was considering a Rega Planet or an Arcam 7se. On the other hand Iwas considering a DAC like the MSB link III. Anyone have any suggestions? I would like a clear upgrade, but I have limited $$$. By the way, the rest of my system is an Arcam 10 intergrated, Aegis one speakers, MIT T2 speaker cables, Nordost blue Heavean IC. I listen to mostly jazz and pop.
