"...You should listen to what your ears are telling you. If it’s not something different you might need to abandon this hobby and try needlepoint..."

The guys that believe all amps sound the same, if not driven into distortion, have either never heard a good system, or have never bought a premium amp, or believe all audiophile products are made just to extort money from the unsuspecting. Frankly I feel sorry for them because their systems must really suck.
Any particular choice of amplifier above a basic good design (about $400 seems to be enough) would be justified only if you deliberately seek some distortion type of your choice.  

Check it out: Totally admits there are differences, but only if you deliberately want them, and defines all the differences as distortion. Intellectual insanity. Pure blather. But there's loads more where this came from.  

Personally, I think we could use a few more people like this. Really high quality components are hard enough to find as it is. Their prices are high in part because so many people want them. Wait times on Tekton and Decware are in the months, to pushing half a year. The last thing we need is more talented discriminating quality-oriented listeners competing for them. The more noobs buying Bose the better. Let's hear it for 'em! 

Louder! I can't hear you! Well no actually I can. But they can't. Hard of hearing. Obviously.

So I guess it’s time to sell all of our amps and buy Chinese $400.00 amps. They don’t make a difference? Nor does anything else. Lamp cord for speakers, interconnects, power. My world just got a whole lot cheaper...

To the OP, Musical Fidelity makes some good products for the $$, best thing to do is audition... really, it’s the only thing to do. Then choose which you prefer. 
the ’all amps with the same power sound the same’ bs got a lift when alan shaw of harbeth openly pushed that line of thinking in his manufacturers’ user group, which he runs with a heavy hand and shouts down points of view contrary to his own

anyone with good ears and some experience in this pursuit knows that this is total nonsense, purely self serving from a guy who sells pricey speakers - even more hilarious to then see him admit he 'just happens to use' a hegel h360/h390 in his in-house speaker testing, listening and at hifi shows... 🤣🤣🤣
The only way to know is to plug it into your system and listen.  Specs are meaningless on a printed page
