As are pretty much all solid-state amplifiers regardless of class. The only thing Class A gives over AB or D is help with the winter heating.Almost all DACs are completely transparent to human ears.

Fixed that for you.ask 10 audiophiles 'Who makes the best-sounding amplifiers?' and you'll get 14 different replies.
Funny thing is, it’s not even the right question!Fixed that for you.
But... you're not saying it's a stupid question, are you?Funny thing is, it’s not even the right question!
Mine has plateau biasing so it doesn't even do that. You have to really rag it for ages it before it starts to get properly warm.As are pretty much all solid-state amplifiers regardless of class. The only thing Class A gives over AB or D is help with the winter heating.

What is wrong with mosfet amps?I have been a long term proponent of class A amps, I still own one, its in the basement gathering dust. If I where to go for very high sensitivity horn speaker, I would consider using them again. Otherwise you are favoring linearity at the expense of intermodulation distortion. I have tried all classes of amplification. My advice: Get the best high power class AB amplifier you can afford (avoid mosfet amps).
Well, in non technical terms, they don't sound very good. Some are quite acceptable for mid-fi systems. You will not find any high end or near state of the art amplifiers (Krell, Parasound, Mark Levinson Classé, Audio Research ect.) with mosfet output stage.What is wrong with mosfet amps?
All the amps mentioned are overpriced audiophile crap. I wouldn't trade any of them for anything I have including Pioneer Class A amps and a stack of Mosfet output stage amps.Well, in non technical terms, they don't sound very good.

Let's seem some legit testing to back this up. A well designed amp whether tubes or JFET of MOSFET or whatever is going to be transparent. Until someone can show that they can hear a difference all the claims of this amp sounds like this or that is just biased and sighted subjective opinion without any value.Well, in non technical terms, they don't sound very good.

Bring a big budget and watch them circle the victim like a committee of voulchers. Spewing all kinds of audiophile prose to impress the unsuspecting buyer.We seem to be getting a bunch of audiophile troll infiltrators here.
Unfortunately Ammir does not test this type of equipment: you are implying that all well designed amps sound the same under all circumstances. If none of the best and acclaimed circuit designers use MOSFET output stage, does not that tell you something? How many amps do you own or have you owned? If I tell you that a Ferrari is a better car than a Chevrolet, is that subjective bullshit of no value? do I need to provide testing backup?Let's seem some legit testing to back this up.

There is plenty of objective data about Ferrari and Chevrolet performance. I have owned and built many amps including MOSFET as well as done blind ABX testing of amps so I have some perspective. The main reason MOSFET are not popular for audio applications is that they produce less power at the same rail voltage so manufacturers shied away from them and so development stopped (MOSFET's moved to high speed switching rather than audio applications). None the less a good MOSFET design is going to be transparent compared to other well designed amps using other technologies. If you have objective data that says otherwise I am open to changing my mind.Unfortunately Ammir does not test this type of equipment: you are implying that all well designed amps sound the same under all circumstances.

I have also built tested and lived with some very good MOSFET amplifiers notably Hafler and an excellent Belgian amp kit by Velleman, simply not in the same category as the ones I mentioned.

You choosing who the Ferrari is and who the Chevrolet is without scientific measurements / method - highly subjective.Unfortunately Ammir does not test this type of equipment: you are implying that all well designed amps sound the same under all circumstances.
