Tube or SS


Opinions please: For a variety of reasons I decided to declutter and simplify my life and thus sold my turntable, my LP's, my CD's and most of my all valve system - except for the McIntosh 275 amp.   my current set up comprises a Cambridge NQ streamer through balanced connects to the Mac and Harbeth C7 ES-3 speakers.  Now, Harbeth recommend using SS amps and I am considering replacing the Mac with the Cambridge Edge W power amp as the two items are designed to work together.  My dealer won't allow me a home demonstration to allow me to compare the amps without actually purchasing the Cambridge ( would give me a refund if I don't like it )  Before I take this route I would appreciate any comments regarding the suitability of either streamer/amp combination.
Thanks all

It’s a no brainer for me if I am getting the opportunity to audition a gear in my home at no obligation. 

What do you have to loose if dealer is willing to refund your money? It’s your system, your room and your ears that are the only and most important factors in determining if Edge W amp stays or goes back.
Of course, but before I do that I wonder what other members views are and maybe if any have had a similar situation
