Okay, we admit it—our Radialstrahler loudspeakers are power mad. Maybe power hungry is a better way to put it. But the fact remains that in order to achieve the unprecedented degrees of transparency, and the breathtaking illusion of the real thing that Radialstrahlers are famous for, they demand unusually high levels of amplifier power.
But power alone isn’t the issue. What MBL’s Radialstrahler speakers really need is an amplifier that can deliver staggering amounts of continuous and peak power, along with a refinement of sound that matches that of the Radialstrahlers themselves.
As a matter of fact, each product in our Reference Series—the 6010D Preamplifier, the 1621A CD and the 1622 SACD Transports, the 1611F Digital-to-Analog Converter, and the 9011 Monoblock Amplifier—is as critical to the MBL sound as is our loudspeakers.
Measuring three-feet deep and weighing in at a hair under 200 lbs., each handcrafted 9011 represents the ultimate expression of MBL’s power amplifier technology. A fully balanced design, the 9011 can be operated in either mono or stereo modes, and is the perfect incarnation of beauty and beast.
A technical masterpiece in the service of music. This high-end treat does not boast yet unheard of measurement data; it simply outdoes everything that was considered the “best” .
The circuitry concepts developed by MBL, such as the “DPP” and “IGC” technologies, are combined here with a uniquely new circuit board design with ultra-short signal paths. Special low-induction components in the passive area make it possible to exploit the full bandwidth.
Special technical features:
- Multi-layer PCB with heavy CU planes in the output section
- Layout in Ground-plane and Eye-of-an-needle technique
- 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
- Technical secrets that we would rather keep to ourselves.
Thanks to the uncompromising, balanced mono design, it was possible to eliminate virtually all sources of interference. Two complete power amplifiers inside the mbl 9011 keep the speaker under absolute control at all times. The input, a single balanced connector on the back, is connected in a purist direct way to the input difference amplifier using twisted 6N copper wiring.
Powerfull yet refined, detailed yet natural, fast but rich, when paired with either our Radialstrahler 101E or 101X-Treme Reference Loudspeaker systems, the 9011 Reference Power Amplifier redefines the term “high fidelity.” It is the closest thing possible to a live event.
