elg2001, I would agree with Dusty. It makes sense to buy components from one manf. if possible. I just did that. First I bought the D200s and the PLC together. Then the VDA2 and VAC. Then the Harmonic Tech cables. Its a bit messy buying everything bit by bit, but each step proved to make a positive difference. If you already have good cables, then probably you can skip these. The D200s are extremely revealing and if cost is an issue, then these would be the ones to get followed by the PLC. The only thing that the D200s lack is a 12V trigger cable, but just listen to the transparancy.... and you will be not care about the triggers. Make sure your speakers are up to the job....!
A few years, back I bought an amp and speakers. I went into the shop and I decided upon a pair of B&W 110i speakers. Next I chose the stands and then we tried out a bunch of amps. The best sound came from an Aura amp. I had never heard of Aura before and never since, but the combination was really perfect. I found out later that in fact the Aura was designed by B&W to match with their speakers - but for some reason they never advertised the fact.
Manufacturers go to great lengths to match up their components, so really the only question is whether you and Dusty share the same sound objectives - I like a lot of detail and depth but not at the expense of smoothness and I don't like my music to be as warm as tubes produce and definitely not clinical like an all digital amp or cold like a solid state. The D200s do this for me. When connected into your system its almost like they are not there between the source and the speakers.
