If you tried to sum up the Axiom Amplifier philosophy in one phrase, it would be "You can never have too much power." We're not all talk, either: we crave power so much we decided to design our own amplifiers to get enough! Introducing the 1500: a spectacular powerful performer that will enhance the dynamic realism of movies and music in your system.

Your System Is Starving

Without enough power, the dynamic scenes in movies lack the excitement of a movie theater experience. When your system runs out of what is called 'dynamic headroom', it often clips, adding distortion to the signal and deflating the sonic energy of the scene in front of you. But when you feed your system pure, clean power, those same scenes come to life with a realism you may have never experienced before.

Power isn't a matter of just 'loud', it's a combination of loud and clean that together create an impression of depth and dynamism, responding instantly to signals coming from your source material and ricocheting it back at you, driving your system to its full potential at last. Without distortion, you can turn the volume up and up and up without it ever becoming annoying or clipping.

Satisfying the Hunger

Look beyond the amplifier's rated watts-per-channel output to its power supply: home theater enthusiasts know that it takes strength and suppleness to deliver power to multiple channels all together, and the 1500 amplifier delivers both. By combining a class-D amplifier with a toroidal transformer and a large storage capacitance, you have the muscle you need to deliver power where it's needed, when it's needed. You won't hear distortion or compression: just clean, endless sound that never clips, overheats or runs out of headroom.

The massive analog power supply partners with the Axiom Digital Amplifier to exceed 90% efficiency: compare that to the typical Class A/B design you find in most amplifiers that waste nearly half the output from the amplifier in heat! Think about the numbers: a typical wall plug is capable of producing 1800 watts on a regular 15 amp circuit. The Axiom Digital Amplifier is so efficient, you can easily achieve 1500 watts of total output: approximately double what a Class A/B design can provide. What does that transfer into in your system?

	8 Ohms	4 Ohms
Max Output per Channel One Channel Driven	325	650
Max Output per Channel Two Channels Driven	325	650
Max Output per Channel Three Channels Driven	325	500
Max Output per Channel Four Channels Driven	325	375
Max Output per Channel Five Channels Driven	300	300
Max Output per Channel Six Channels Driven	250	250
Max Output per Channel Seven Channels Driven	214	214
Max Output per Channel Eight Channels Driven	188	188

Understanding the Equation

Although output with eight-channels driven looks small, the fact of the matter is that the power demands from surround channels in a home theater system are much smaller than the power demands of the front left, right and center speakers. As a result, the real-world experience with these amps is lots of power available for the power-hungry front section. a seven-channel amplifier used in a home theater system acts more like a five-channel amp for power-per-channel, as shown in the chart above.

For rooms under 2,500 cubic feet and normal sort of volume levels the 1000 series is perfect.

For rooms over 2,500 cubic feet or if you like to really crank it once and awhile then the 1250 series is the one.

For huge rooms and/or the desire to achieve the nirvana of loud and clean the 1500 series is the answer.

Axiom amplifiers can be connected to either the pre-amp outputs on your receiver (check your receiver has these) or to a stand-alone pre-amp processor.

The force you need to make your music and movies come alive

Find out how enough power can create the realism you're yearning for in your home theater system: experience the energy efficiency provides and get spectacular performance from your movies and music with the Axiom 1,500.

Customer Comments about the Axiom Amplifier Family

Below are a few of the many reviews that our customers have been kind enough to send us.

Sound is delivered so crisp and clear. You can keep pushing it more and more without feeling like you'll damage your speakers. I listened at near reference levels(short amount of time) during Lord of the Rings and Saving Private Ryan and there was no distortion, just clean sound. I didn''t get this with my old Denon receiver. Separates do help. Detail, accuracy and punch is what you will receive with the ADA 1250. It's a great match with the Axiom M60's, VP160 and QS8 speakers and a Marantz pre/pro. -- Brad P., ON, on the ADA 1250 I have been using this amp for a while now and this is my conclusion - THE BEST amp I ever had. I doubt that I will have to replace this one for at least the next 10 years, and that's saying something when in this fast moving world, today's technology is often - old. Not so with this amp. I like to listen LOUD to both music and movies. As I have excellent hearing, this is a blessing. I can hear every little detail, especially in Blu Ray DTS master audio discs. I have the Axiom Epic 80-800 speaker system, including heights, and the Marantz av 7005 processor. Anyone looking for a super amp that will give you all the power you want and need at a great price, and, will still be the heart of your system years from now, what are you waiting for? -- Egbert R., NB, on the ADA 1500

With the ADA-1000, I'm able to hear greater sound depth from my M60s that I wasn't getting with my A/V receiver alone. My system sounds great now, and if I ever get the itch to upgrade to M80s and a VP180, I have peace of mind knowing the ADA-1000 is ready to supply good, clean power to these thirsty speakers. -- Derek K., VA, on the ADA 1000 I am running a 3 channel 1500 with my Paradigm Studio 100s and 690 center. I am no audiophile for sure. But I did indeed hear a major improvement. What struck me most was how the whole range just opened up. Everything got cleaner and more transparent. At higher volumes there is no "pain" in listening. None of that garbage getting in the way of the music. It has made listening a much more enjoyable experience. Oh, and for movies? Yes, all the slam you could possibly want. Never a hint of stress from the amp or the speakers. Love It! -- Jim R., NE, on the ADA 1500
