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

I would pair your Plinius pre with a Plinius amp.

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.

I agree that the Cambridge CDP is the weak link in my system so I went for an adeventurous upgrade - swapped it with E5 Esound from cattylink.com in HKong. I can summarize my experience as follows:

- The unit has arrived in excellent shape and it was a
timely delivery - the packaging was immaculate and
very professional. The documentation is great!

- The sound in my system has improved profoundly. It has become very lush with great detail and an amazing imaging and soundstage. It has also become very natural and has a tube vibe to it.

Note that the player has costed me USD 1000 including delivery by DHL - I find that it surpasses its league in terms of price point.
