Meet The Family
The family of Atoll power amps sounds SO GOOD, at such fair pricing, that I want to be sure you’re aware of all three. Each is a class leading performer at its price point.
All Atoll products start with massive power supplies that make their price similar competitors blush with embarrassment. As you study these power amps, be sure to check out the inside photos we’ve provided- and compare them to what the other guys offer.
Even a casual look will make clear that Atoll provides you with a generous array of hardware. Their construction is a work of art. Virtually all competitors are a spaghetti bowl of wires connecting multiple PCBs.
Atoll amps are built with through hole parts vs surface mount parts. These sound better, resist heat build up, and make any repairs down the road no problem.
All of these amplifiers use a PAIR of very large transformers. They’re true dual mono designs. They all use a high value of filter capacitance. They all use MATCHED MOSFET output transistors. As you go north in the line, you get larger, and more, of these outstanding parts.
The benefit of employing very substantial parts is that you get deeper, stronger bass, and superior dynamic range compared to flimsier built amps.
You will find that all three of these amps produce much more power, and specifically deliver more testosterone in the bass, than like priced competitors.
You can flat out dismiss watts per channel ratings when you evaluate Atoll amps. Due to the formidable supplies and exquisite build quality, Atoll provides cleaner, quieter sound with power and dynamics you didn’t know your speakers had.
Atoll’s MATCHED MOSFET output transistors are essential to smooth sound. Output transistors have sonic fingerprints, because in the real world, none of them are 100% spot on to a beta design.
Imagine the ideal transistor performs like a perfect circle, meaning, there’s no distortion. In reality, since none are perfect, we want to match transistors that have fingerprints that are so close to each other that it’s impossible to distinguish differences among them. To do this, Atoll measures and matches transistors before they get installed. This is a painstaking effort that few companies will take the time and trouble to do. Atoll has created its own test gear to accomplish this at an efficient pace.
The other guys out there buy thousands of transistors and just slap them in amps as they come out of the box. The particular amp that ends up at your house can have all manner of distortion characteristics that results in a beehive of grainy sound.
If you have a power amp in your system that’s a couple decades old, please consider updating. You’ll hear smoothness, weight and impact from your speakers that you had no idea they could produce. Time has marched on. Even AM100 will trounce high brow names from a couple decades back- at much less money than you spent then. AM200 is stronger and more refined. AM300 is 25% stronger and a match for the best speakers going. Further, AM300 can be run in monoblock config at 500 watts per block. It’s ALMOST too much fun!
