Pairing Plinius 9200 pre-amp w/ Nuforce Ref 9 amps


I've been seriously looking at adding Ref 9 Mono's to
my current system:

-Plinius 9200 Integrated
-Cambridge Audio 640C
-Dynaudio Audience 82 speakers
-Tranparent MuiscLink interconnects
-Transparent MusicWave cables

I have not found any reviews or feedback on pairing the
pre-amp section of my Plinius with Nuforce Amps. Has anybody done/heard of and reported such an experience - if you do would you please share it with me? all feedback would be appreciated..

Would like to test the waters with the Nuforce Ref 9's and eventually build a second system around these if their raving reviews meet my ears expectations - even though I personally found Plinius amps hard to beat according to my experiance! The reviews and the price point for those puppies sound incredible!
Much bigger sonic improvements can be had by upgrading your source before your amplifier. As good as the 640C is, it is still a budget CD player and rather out of it's depth in your system. If you put that money into a CD player from Naim or Copland for example, I believe you will yield a much greater sonic gains than you would upgrading the amplification.
I agree with fourcheeks about the source, but would add Exposure, Arcam, and Musical Fidelity to the list.
