Amps with meters ...

Any added piece of electronic that is not totally justified added also noise to the floor level noise...

Preference here is for no fancy stuff.  I am having a pair of monoblocks made and the faceplates will have one very small LED and the manufacturer's name engraved, without the model name/number or anything else.  After it is engraved, the whole faceplate will be powder-coated black so the engraving will show as a somewhat subtle shading contrast.  Since all my gear is kept in a heavy, well-braced mission style cabinet, except the amps and speakers, my listening enjoyment does not rely on my being able to look at the gear.
All that said, I still remember being awed by the first high-end system I ever saw.  My friend's dad was an attorney and had a full McIntosh system with meters everywhere!  I also appreciate the retro look of Ralph's Atmasphere gear.

I like meters. They look like little conductor's batons keeping in pace with the music.

Yes no doubt amps with VU meters are better than amps with LED. Unless maybe lots and lots of LED. Whole bunch of them in rows by frequency. With dials. And sliders. Lots and lots of sliders.

"Some listeners may find that the amplifier sounds better with meters."

Count me in. Maybe not "sounds" but "overall experience".

"...and the manufacturer's name engraved, without the model name/number or anything else."

Why put the manufacturer's name there? I would skip that first.
