Living room system: class A or AB amps?


Would class A be suitable for a living room system? Apart from hi-fi listening sessions, it's also used a lot for watching TV.

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.

For this system, I have so far only purchased the speakers: Focal Stella Utopia Evo. Room is big: 1,200 square feet with openings to hallways.

I'd consider to pair them with Gryphon Mephisto and Pandora. But that's class A...

Opinions and amp suggestions are welcome!

robert1976: "Did you just call your fellow forum contributors "schmucks"?"

Hello robert1976,

     I believe he actually called his fellow Audiogon members "schnucks".

     According to The Official 2020 Audiogon Forum Discussion Rulebook, often informally referred to as "The Bible", it unequivocally states the following:

     "If an Audiogon member calls another official member a derisive name but misspells that derisive name, for example intending to call another member a "schmuck" but misspelling it on a post as "schnuck", then it is not only officially permitted by Audiogon for fellow members to refer to this mentally challenged member by numerous similarly derisive names without penalty for a period of 1 year, it is in fact highly encouraged.               Furthermore, if the offending misspelling member is a repeat offender, such as our especially dimwitted member bigdaddy2, then members shall feel free to strike down upon thee with great vengeance and furious anger those that attempt to poison and repeatedly misspell the English language.
     According to a recent statement from the author of The Official 2020 Audiogon Forum Discussion Rulebook, Samuel L. Jackson, "our rulebook committee has just unanimously decided that fatdaddy2's misspelling of 'schmuck' as 'schnuck' represents such a major mental malfunction and high degree of schmuckery, that, beginning with the 2021 edition of our Official Audiogon Forum Discussion Rulebook's Supplemental Dictionary, we will be placing a picture of fatdaddy2 as an example in the dictionary's entry for the word 'schmuck'. "

Thank you,
 Tim
Clayton Audio Class-A amps fly under the radar but get stellar reviews and most models have a high/low-bias switch.  The S2000 would sufficiently power pretty much anything and costs $11,500.  Just another option to consider, and best of luck. 
Personally, I have my stereo on most of the day if not 24/7, so AB for me.

If you are looking into class A, consider the Lusman 590, which has much more power than it's spec.

Class A amps do sound good very quickly after fire up, and I prefer the ones I have, anyway, to many Class AB amps.

The downside is that the smaller versions of my amps put out 25 watts of sound and 300 watts of heat, and power consumption is accordingly high. (I believe mine put out 40 w and emit around 400 watts of heat)
