Who is the KING of MONOS?


WHO IS THE KING OF MONOS???

Mcintosh 501:
Big. Heavy. Reliable. Built like a tank. Smooth and pleasing. This chuck of metal will flow liquid sound at you all day and not even get warm. It is Fun to listen to and fun to look at. Arguably the best looking amp of them all. Some accuse it of being too laid back. Others would consider selling an appendage to obtain a pair.

Krell Evolution 600e.
Pretty. Maybe not Mac pretty but still pretty. Unlike lesser Krells it is smooth and articulate. Possibly possesses the best bass of any amplifier anywhere. Expensive. If it can be the King it should be expensive.

Cary SA 500.1
Probably has one of the best reviews ever written. Cary is said to be a perfect middle ground between Krell and Levinson. Not too laid back. Not too harsh or dry. Just perfectly nestled in the middle. Not big or heavy. A little plain to look at. Middle of group price tag. A few complaints floating around about reliability. A few complaints that Cary is cheaply made. Is it worthy of a King’s Crown? 10 Audio thinks so………

Levinson N 53.
It is pleasing to the eye. It has lots of clout. It has cost no object claims. It costs a lot of big American Dollars. It has a non typical switching power supply. Levinson is sometimes accused of being too warm. Is this the case the N53? The company has encountered a lot of turmoil in the recent past. Can it overcome the negatives and beat the rest? Will the new D technology be its demise?

Classe CA-M600.
Aesthetically pleasing but doesn’t match anything else. Another smooth operator. This amp has also been accused of being too laid back and polite. Sometimes polite is a good thing. Can it be the polite King of Monos?

Pass Labs XA600.5
Can anything negative be said for this beast. Another block of beauty that has a glowing meter. A little magic and a little hocus pocus maybe. I can see the others getting a little nervous with the Pass in the mix. If only the company would answer the phone and tell me who the dealers are. I hope the product is better than their customer communications.

Wyred4Sound SX-1000
Can it even fit in with names like this? According to the reviews and the manufacturer it can. Its Class D. Its Light. It looks good. According to a lot of people it does things Class A / AB cant. It is by far the cheapest or cost effective of the group. Can this economical wonder compete or beat any of these brutes? Will it wimper and run away with its tail between its legs? We shall see.

Let us discuss who the King should be. Let us discuss who it shouldn’t be. Who cares about price. This is a Royal group. Who is the best of the best? No one wants to hear “They all sound the same.” Don’t waste our time. These boxes have magic inside. Who has the most? Which one should we all be dreaming of when go sleepy at night?. Who is the King Of Monos?

Are there any Class A amps that do not run hot?

None that I know of, but of course some run hotter than others. For example, the Pass Aleph 3 seem to run considerably hotter than the XA30.5 -- don't know why.
On a related note, I sold the fantastic sounding CAT Jl2 because it raised the temp in the room 5-7 degrees in the summer, I can only imagine what their mono-block would do in terms of heat. That is the price you pay for Class A, but it does sound great.
Husk01: "Are there any Class A amps that do not run hot?"

The answer is no. An amplifier biased in class A at it's theoretical best is 50% efficient. This means that 50% of the power delivered by the amplifier is dissipated as heat. In the real world however, efficiencies run from 15% to 25%. The worst case for a class A biased amplifier is when there is no input signal where all of the power is dissipated as heat. Such is the price we pay for zero crossover distortion.
No Question about it FM Acoustics. I have the the FM Acoustics 115 Mono's and if anyone would like to come hear them you are welcome. They are by far the best amps we have ever heard. and we have had many including the 811 MKII and most of the amps that are said to compete against FM. You may think we are biased but I will challenge you to bring any amp you wish to compare..
