Cambridge Audio 540C Version 2 vs CD6

Cambridge Audio 540C Version 2 vs CD6 which is better?Cambridge Audio 540C Version 2 is this a good up grade?
i have owned linn audio, krell, cary , and cambridge is not there, why should it be , the other is three and four times its price range, i have dropped down to a smaller system and sold everything off and bought a 640 player and amp because of the pricing and i think they are very good, very good is and understatement... they sound like tubes at times but they are solid state without the hassle....they have alot of great inputs and the player is excellent with the dac it has enjoy...if not let it go....
