Which is Better? Musical Fidelty A5 (used) or new Rogue Sphinx?


I currently have an NAD C 375 BEE integrated amp running a pair of BW 804S speakers. Have urge to get new integrated amp. Have considered a used Musical Fidelity A5 (it has lots of power) or a new Rogue Sphinx (not as much power but sweet sound). Listen mainly to classic rock and blues with some classic jazz and little classic country and western music. I also like it on the loud side. Can't decide. Which choice will give me the biggest upgrade over the NAD? I'm counting on some input from the membership.

Thanks

My 2cents worth.

I have the A5 Int, and run B&W CDM1NT bookies.

A good pairing; the B&W's respond well to the grip and grunt of the A5.

I too like scare the neighbors from time to time - the A5 has the power to keep it clean.

Let the B&W hate begin.....
I can't see the A5 as a good choice. I used to have one. It does have a lot of power, buts a very forward and aggressive sounding amp. It takes the concept of PRAT way to far. All attack and no body. That's the last thing your speakers need. A higher end NAD would probably be a good choice.Also have a look at Marantz or the new Parasound Halo integrated.
That’s what makes this hobby so difficult -everyone's 'end result' experience is different.

There isn’t one review of the A5 that describes it as forward or aggressive, nor has it been my experience.

The advantage of either as a used buy will be the ability to flip it back with little/no loss which affords the user to get direct ears on experience.  Both will hold their value in the short term.

Different strokes.
