ADA 1000 features.  Click to enlargeGetting the most out of your home theater and music listening depends on one thing: feeding it with enough power to really show off the quality of the system. High-end speakers need high-end power to show their capabilities, and the new 1,250 has that power in spades!

Why Power Is Paramount

If you under-power speakers, when they reach a challenging passage your amplifier will go into what is known as clipping, creating distortion as it struggles to keep up with the signal. That distortion is what we typically mean when we say something sounds 'too loud' - the displeasing noise stands out for us and we want to turn the sound down.

But when you have enough power going to all channels of your system, you'll never hear distortion. All you'll hear is the thrill of the action taking place - dynamic explosions, rousing crescendos - and the true capabilities of your high-end audio system.

How To Get It

Getting enough power means understanding the numbers. It seems straightforward: look at the number of watts-per-channel and get the one with the biggest numbers, right? But that's not really how it works. You see, traditional Class A/B amplifiers lose up to half their power in heat - totally inefficient. But the proprietary Axiom Digital Amplifier closely controls our Class D power supply at over 90% efficiency, translating into 1,250 watts of pure power available at any time for your system. Let's look at how that breaks down over the number of channels you're playing:

The amplifier features a toroidal transformer and a large storage capacitance, housed in a heavy-duty steel case with an aluminum face channel.

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.

Experience the life-like sound levels possible with a no-compromise amplifier like the 1,250: no clipping, no distortion, just sound that goes on and on. Hear everything with the 1,250 amplifier.

 

Professional Reviews

Industry Reviews of the ADA Digital Amplifier Family

"[The ADA-1000] is a great-sounding amplifier. I was impressed by the sound quality of this budget-friendly amp, and was more than happy to have it in my reference multichannel system for an extended period. At only $1340 for the five-channel version, few products compete with it at anywhere near its price. If you're looking for an amplifier to add some power and refinement to a budget-minded system at an almost unbelievably low price, look no further."
-- Roger Kanno, SoundStageExperience.com

"As the garbage truck plowed through the street jam-packed with cars, this powerful scene was filled with smashing metal, breaking glass, screeching tires and dozens of horns, among other sounds.  The ADA 1500 easily sorted through all these sounds and reproduced them with a frightening realism.  In many other parts of the movie, the sound of people screaming and gunshots were chillingly real.  With the  volume turned up, I was getting a true movie theatre experience from the comfort of my couch. . .The audio reproduction was so very realistic, I got goose bumps when familiar songs came up. . . The sound was so engaging I simply got completely lost in the performance."

Customer Comments

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
