Living room system: class A or AB amps?

PASS 250.8 or 350.8 asap!!

Would that be enough for the 374lbs a piece Focal Stella Evo’s? I’d rather risk a little overkill vs. underpowering them. Guess X600.8 monoblocks then?

Robert, it sounds like you know your answer about Class A.

Not so sure yet. Just read class A sounds good too without a warm-up (although better as temperature increases). I live in a tropical climate and my room temp is always at least 25°C / 77°F.
That may shorten warm-up times compared to a system in a Canadian basement in winter :)

For watching TV? Okay....

Luxman monos will give you superlative performance.  Don't second guess it.

robert1976 OP Would it make more sense to get good class AB amplifiers, which can be switched on permanently without drawing huge amounts of power? I wouldn’t want to warm-up an amp first before getting good sound.

Get an Gryphon Antillion, (switchable Class-A Bias) that way you can switch up the Class-A only when you listen.

Leave it on in low bias all day, then when your ready just switch it up, and remember when you listen to a Class-A amp up to a point the louder you listen the cooler they run.

Think of it as the water pressure behind a tap washer, the pressure (is the amp heat) the more you let the water flow (listen to music) the less pressure there is behind the tap washer, turn of the tap (music) and then the pressure (amp heat) is at it’s greatest.

This is why when you listened to the massive classic Mark Levinson ML2 monoblocks, they ran cool as a cucumber, stop listening and they got very hot, even though they were only 25w full power at 8ohm, but that 25w was all Class-A.

You choose between Class A or Class B
                                    Rock or Classic
A lot of power
Aestheticly speaking : no blingbling , no meters , no firecrakers.
But it is expensive .
