Why would anyone want class AB amp when class A always sounds better ?

I might be off here, but class A amps don’t drive lower impedance speakers very well either. Most class A amps aren’t stable into 2 ohm loads. Krell being one Of the exceptions.

The class of operation has nothing to do with what load impedance the amp can drive. They simply aren't related, plain and simple.

I have a First Watt Sit-3. (Class A)
It does not get hot.
18 Watts can provoke ear-bleeds with Cornwall IV's.
Efficiency?
YES! ;-)

Hi,
I compared the sansui AU-777A and sugden A21, i preferred Sansui, and my best integrate amp is Sony ta-5650, really better than two amps.
The sound of the Sony is the same than pass first watt SIT (V-fet transistors), the new name is SIT.

Reading all of the responses from a simpleton’s point of view is very interesting. But the ultimate measure for any piece of hardware is the one thing that’s totally unique for each person. How their complex inner ear relays information into the brain, which works out what’s pleasing to the listener. Not to mention the endless variables that change our hearing over time. You can’t tell someone there wrong when you don’t have their ear and brain.  Never mind the biases we have from where and when we were raised  

What’s the best amp made?  It’s the one I have.  

You may fire when ready

Hello. Interesting debate. I’m in the market for integrated amp to pair with my Goldenear Triton 2+ speakers. In the next couple of weeks I want to demo Pass Labs Int-25, McIntosh Ma-352, Luxman 509/507 590/550 depends what dealer will have in stock and maybe even Arcam Sa30(first 20w in class A)
I don’t care about measurements or numbers,all I want to hear is beautiful music. I rarely go over 85db in my medium size room so I think any of those can do that. A,A/B,G.One of them will win.
Cheers
