MBL 9011 Reference Monoblock Amplifiers

Up for sale we have a pair of MBL 9011 mono block amplifiers. can be used as stereo amps if preferred. these are part of MBL's Reference line and are their current top of the line amplifier. They are in amazing condition. we also have available the matching Preamplifier,Transport and DAC as well as a complete HRS MXR rack system and amp stands specifically made for the MBL system.

Power to Spare?
The 9011 is rated at 440W into 8 ohms, 840 into 4 ohms, or 1390 into 2 ohms. Its "Peak Pulse Power" rating is 5000W into 2 ohms. But really, if you own 8 ohm speakers, all that physical heft gets you just 440W—still plenty, but somewhat surprising given the 9011's weight and size: 19" wide by 13" high by 34" deep. If you look at MBL's spec sheet, you might notice that the 9011's maximum output power into 8 ohms is identical to that of MBL's Reference 9007 amp, which I reviewed in September 2006 (Vol.29 No.9). Into 4 and 2 ohms, however, the differences become obvious between the 9007's single 400VA transformer, four 3300µF capacitors, and 12 output transistors and the 9011's three 400VA transformers, eleven 3300µF capacitors, and 24 output transistors.

The 9011 is capable of delivering three times the long-term power output and twice the short-term current delivery compared to the 9007 and that becomes important when you ask an amp to deliver power into a complex real world load, rather than into a simple constant-impedance test bench load. Of course, brute-force power isn't everything. The 9011's peak current output is 50 amps compared with the 9007's 30 amps, which is a significant increase.

The 9011's frequency response is claimed to be DC–200kHz! Its distortion is rated as an impressive <0.001% at 50W into 4 ohms at 1kHz. The signal/noise ratio of 118dB, A-weighted is also impressive.
