Onkyo A-9070 overview

  • 1Description

The A-9070 Integrated Stereo Amplifier from Onkyo offers four discrete modes; integrated amp, power amp, pre-amp, and split power/pre-amp to provide great flexibility when incorporating other components into the hi-fi system. Alone, it provides ample power with a parallel push-pull amplification design, three-stage inverted Darlington circuitry, dedicated Wolfson 192kHz/24-bit DACs for symmetrically designed L/R channels, and four large 15,000 µF capacitors.

To preserve signal integrity, the unit features DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry). Closed ground-loop circuits and vibration-damping construction combine to produce clear sound across a wide dynamic range. An independent headphone amplifier, a phonograph equalizer, and gold-plated audio terminals/speaker posts are evidence of high build quality.

The A-9070 Integrated Stereo Amplifier is for hi-fi newcomers and more seasoned music lovers looking to upgrade their equipment.

New DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry) dampens super high frequency distortion
Closed ground-loop circuits, HICC (High Instantaneous-Current Capability), and vibration-damping construction combine to produce a startlingly pure sound across a wide dynamic range
The unit's four 15,000 µF capacitors keep plenty of power at the ready
Efficient parallel push-pull amplification paired with three-stage inverted Darlington circuitry works at reducing distortion to almost nil
Separate Wolfson 192kHz/24-bit DACs for both left and right channels improve performance
The unit is also equipped with 192kHz/24-bit HD audio playback to handle modern formats
Four discrete amplifier modes-integrated amp, power amp, pre-amp, and split pre-amp/power amp-offer flexibility when integrating other hi-fi components
Details like an independent headphone amplifier, a phonograph equalizer, three digital audio inputs, four analog inputs, and gold-plated audio terminals/speaker posts speak of the highest build quality
The superb craftsmanship, technological refinement, and attention to detail invested in the A-9070 make it worthy of serious consideration for those in the market for top-shelf hi-fi gear

    Onkyo A-9070 reviews

    A-9070 Integrated Stereo Amplifier is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from Onkyo A-9070 More for your money The A-9070 is use in a two channel L/R platform. At first it was use as the hub for my different audio units both old and new, and with it 192/24 bit Wolfman DACs the sound is outstanding. Now I added a pre amp to this system and the A-9070 is working as a power amp and the sound is even better than before. The sound is good using LPs,CDs or using a dock with USB or iPod. So if you are looking for a amp that is flexible for now and the future - check out the A-9070.

    Rated 5 out of 5 by from Fantastic performer ...great amp. with tremendous dinamic and musicality.No meter what you put in this beast the result will be pure joy - more you listen more you wish to continue listening .It's a true hi end amplification and can be compared with much expensier competition like with Vincent VS 237 costing more then twice.Listening both amp 1 hour ,I decided to buy Onkyo despite Vincent was a bit better in some area but in over all impression,Onkyo was a winner

    Rated 5 out of 5 by from Great sounding amp Extremely good sound for the money with lot of power reserve and dynamic.It is very important to use headpones time to time because there is a contact problem with phones switch in the amp - this switch switches off and in the speakers and when it gets dirty,the sound quality can be somewhat bad....or put the contact spray in the phones socket
