Amps with meters ...

The meters on my ARC 160  monoblocks are not accurate. But they sure are pretty when I choose the lowest level of light in the window from which you can see the tubes within (one can adjust the brightness within the double paned plastic window on the face of the amp) . Call me shallow--- but since the amps are in my living room, it is an added bonus to the sound when they look good.  I would never buy a component based upon looks, but I would certinly not avoid one because it looks good.

Ha! Awesome 😎 

Everyone has their preferences. Life would be boring otherwise. Let the 'meter talk' sink in a bit. Now imagine building a custom home for a client...

Tuners with oscilloscopes are the best tuners 

I have Mac MC2600 and Pioneer SPEC-4 power amps.  I like their  meters and rotary left/right gain controls.  I use them with pre amp volume controls to get much finer output control.
