Question on Pre amp to match with Cambridge Edge W


Hello all,

Got a great deal on a new Cambridge Edge W and loving it so far.  In the next couple months id like to upgrade into a pre amp to match with it.  Obviously the Edge NQ is a perfect match, but not sure if the longevity for the price is there.  

Would a Macintosh C49 /53 or C2600 / 2700 be a better experience and better resale?  

Any input would be greatly appreciated!
