I am surprised that just from reading the phrase "entry level high end" you

I'm assuming you have something ccomparable to a NAD or Rotel or maybe a
notch above that.

With normal speakers and listening volumes, you'll never really hear the
differences, though you may swear you really do(ie - it's your mind playing
more $$=better sound tricks on you). Extremely difficult speakers like
Martin Logans and such of course, will tax any amplifier. A pair of
Joseph Audio or Tannoy or simmilar speakers? No problem at all for most
100wpc or so amplifiers.

Of course, change to better speakers... Watch your eyes open wide at how
much it immediately improves. You are far better off auditioning speakers
in your home first - because you'll get far more improvement for your
money here than by a few percentages here and there by replacing components.
