For those without the space required to house a pair of MBL’s massive 9011 Reference Power Amplifiers, may we suggest the next best thing? While the 9008A Reference Power Amplifier is similarly authoritative, transparent, and beautiful sounding, it takes up a foot less of space, and weighs in at a mere 132 lbs.

 

It’s still no small fry. But the fact remains that in order to achieve the unprecedented degrees of transparency, and the breathtaking illusion of the real thing that our Radialstrahler speakers are famous for, a powerful amplifier is an absolute must.

 

But power alone isn’t the issue. What MBL’s Radialstrahler speakers really need is an amplifier that can deliver enormous levels of continuous and peak power, along with a refinement of sound that matches that of the Radialstrahlers themselves.

 

Measuring 24-inches deep, each handcrafted 9008A exemplifies MBL’s perfectionist approach to everything we do. A fully balanced design, the 9008A is essentially a slightly smaller version of the 9011, with the same basic parts and circuitry.

 
This true analog power amplifier is built only with discrete components of highest quality. Neither integrated circuits, nor microprocessors are involved in this design. Our engineers have created a true balanced design. In mono operation 2 full range high quality power amplifiers (in- and off- phase) driving the speaker without any ground connection. On the rear panel you will find a balanced connector with gold plated pins to connect the amplifier section direct with the input signal. Though, there is a possibility to drive this amp in Stereo too, for this operation you will find RCA connectors for unbalanced Stereo operation. The Stereo input signal is connected by using drilled pure 6N copper wire direct to the input of the electronic board. There is no relays to switch between Mono/Stereo operation to avoid any influence by contact distortions. This power amp is offering incredible flexibility, but mainly sheer power for passionate music lovers. Using this High End power amp in a home theater setup you get a sound quality level you never believe that this can be happened. In short, the mbl 9008 A is a technical masterpiece manufactured in the service of music.

The circuitry technology concepts developed by MBL, such as the "DPP" (Direct Push Pull) and "IGC" (Isolated Gain Cell), are combined here with a unique new circuit board design with ultra-short signal paths. In addition, special low-induction components in the passive environment make it possible to exploit the full bandwidth of this amplifier.

- Special technical features:
- Multi-layer PCB with heavy CU planes in the output section
- Gold plated copper planes
- Layout in "ground-plane" and "eye-of-an-needle" techniques
- Low-induction MPC resistors and MHz-type RSH capacitors
- Super-fast ring-emitter transistors in X-crossed array
- Regulated power supply for the Class-A drive electronics
- Custom MBL-built binding posts made of pure copper
- No output relays
- 198.000 uF custom built "long life" power capacitor bank
- Pure copper internal wiring 6NCU
- DC servo coupling
- Flat frequency response to beyond 350 kHz
- Outstanding mechanical structure, in a compact housing
- Technical secrets that we would rather keep to ourselves.

This fully balanced differential amplifier employs 2 custom built toroidal transformers for the power stage and 1 custom-built, fully-shielded transformer for the driver stage. All transformers are mounted on a metal shield and encased in epoxy for ultra-effective damping. The output stage and the driver stage employs separate supplies to fully isolate the output stage from the input stage.

But as proud as we are of our technology, it all comes back to the music. MBL’s music systems leave listeners stunned by their extraordinary levels of detail, transparency, tonal beauty, and jaw-dropping presence. Can’t get to the concert hall tonight? Not to worry.
