JEFF ROWLAND Model 201 Monoblock Amplifier Pair. $0. At $4,000 you'd be hard pressed to find a stereo amplifier with this kind of build quality and performance. The fact that these are actually monoblocks will make it nearly impossible. Nearly mint and tested very well in the lab. Perfectly matched and balanced.

The JEFF ROWLAND Design Group, in the few years that they have been internationally visible in the audio high-end, have become solidly entrenched as one of the industry's heavyweights. But their Model 1 amplifier is almost petite, a significant departure from their flagship—the three-men-and-a- (husky)-boy-required-to-lift monoblock Model 7.
The design concepts and circuit topologies of the Model 1 are similar to those of Rowland's higher-powered amplifiers. The smaller physical size and reduced power-supply capacity—reflected in the more modest power output—are the only significant differences.
The Rowland Model 1 also provides for adjustable input impedances of 600 ohms, 20k ohms, and 100k ohms. Rowland makes a case for 600 ohms input impedance being the proper load when used with a source capable of driving it (their own preamps are designed to do so).
The monoblocks JEFF ROWLAND model 7 last model , are absoluteky the est if the best in Audio hi end at any level of the price and with constructive and manufacturing quality at top 5 stars. Infact them having been built in very few examples and handcrafted by hand.
