OK I'll give you that.  A 592 signal  WILL in fact, sound different from a 599 signal.

What you just posted is a combination of fact, fiction, and oversimplification.
I can absolutely discern the difference between signals received from better and lesser transceivers if the disparity in transmitted signal quality is sufficiently large.
Conversely, I am routinely complimented of the "clean" quality of the signals I send and the fidelity maintained in them from folks that have no idea what my equipment is.
Not ALL 5 watt transmissions are created equally....  that can be demonstrated both qualitatively as well as quantitatively.
Some transceivers are superior to others.  Tyat is a simple fact.  Even with two identical transceivers, one then must consider proper calibration, setup, and ancilliary equipment....  power supply, microphone (huge potential diff especially in concert with pre-processing of signal put into transceiver front end), grounding, and then of course....  the ANTENNA SYSTEM composed of everything from the antenna connector to the tip(s) of the radiator(s) and return paths.
5 watts into a dummy load is most definitely not the same as 5 watts into a practically perfect radiating system....
Even into 2 practically perfect radiating systems, ground, elevation, et al. come into play....
Enough of that...  point made...
To the OP....Great QRP contact, N9AA....  keep it up, Scott!

As the saying goes, "Five watts is five watts".

I think what you're actually saying is that you're amazed at what can be accomplished at QRP power levels.

Remember, if you are being received at 20 dB over S9 while running a kilowatt, you'll still be S5 at 100 milliwatts.

Just worked TX5T on 14.028 with 5 watts on the KX3. I don't usually brag, but this was a nice QRP contact.
