Amplifier brand/designer with the most unique and consistent “house sound?”

McIntosh has quite the house sound. Muddy and grainy or lush and detailed. Depending on how much your drinking.

I love it.

Conrad Johnson has literally sounded the same for 40 years. From a PV2AR & MV45A to ET3SE and MF 2550SE, more refined as time goes on, but to my ears still lush and detailed regardless of how much I drink.

Hey @jjss49 

Not sure if I can be as articulate tonight as I have been in the past, but to my earst the Ayre amps seem to darken the room, as if they could suck the noise out of it and leave you with less of your room and more of the music. It's a very distinct feeling.

SONY. Not only amplifiers over decades, but other items, too. Very strange. To me, at least.

Digital Amplifier Company.  Tommy O'Brien's class D's are not an off the shelf module purchased from another company.  He designed the amps himself, and they do everything right.  Airy, soundstage, wide band frequency response.  I have two different versions, the original DAC 4800 upgraded to a Mega version and two STM Cherries.  I also have a DTM on order.  For me, they just present the music better.
