What class of amplifier has the most high definition sound ?

You can listen to an amp that that tested off the charts in the lab, has the greatest reviews, in your setting sounds sub par. I think end of the day, it’s the pairing, room, setting, and the hearing and how one process the sound and the music. I’ve had $$$ amps and tried low wattage boutique amps that sounded better, to MY ears. I’ve had arguments with friends that tell me I’m foolish for spending what I did on gear, and say their blu tooth speaker sounds great.  End of the day, there are more factors to the equation.

Would like to know where the Devailet amps score in this? (Class A in parallel with Class D).For those familiar with them please chime in.

I have a new definition.  With research (listening research) and a budget that matches your research, it is the amp you bought given the rest of your equipment.
