from Alamo Summary:
I am a former designer of amplification equipment, designed a hybrid trnsistor array back in the 1970s for IBM.
The Rowland Research Model 7 is perhaps the finest amplifier ever conceived.
It has the power capacity to play any speaker with sonic accuarcy heretofore unknown. It can be as warm and authentic as a vacuum tube amplifier and get just as hot (BTUs) too.
IT is best served with a speaker that can take advantage of its ability to deliver sufficient power for any musical passage. working best with active electrostatic speakers like Martin Logan's CLS-IIs. THese speakers demand gobs of power and will alter their impedence during the course of any musical passage. The Model 7s can deliver from 350 watts at 8 ohms to a whopping 1200watts at .2 ohms without changing any settings further with built in power conditioning you plug the Martin Logans right into the Amp's power supply.
For listening to jazz there is no better combination, the Logans and model 7s give a live sound stage with extremely accurate 3 dimenisonal imaging even in a stereo (2channel) only envirnoment.
I also recommend matching the MODEL 7s with one of Rowland's superb Coherence preamps.
I send my Model 7s and Coherence preamp back to Jeff Rowland once every four years for calibration and updating, there is a high cost of freight but Jeff usually finds something new to tweak evrytime and rarely charges for the enhancements.
the last time internal wiring was upgarded to a silver gold alloy and the sound improved dramatically.
i also recommend using the highest signal integrity cables available. Cardas usually workd very well. And in a fully balanced set-up if you can. Strengths:
Sonic Accuracy
Signal to noise ratio.
Awesome Power delivery
Onboard power conditioning
3d sound stage Weaknesses:
weight
power consumption
placement of two mono blocks
needs heavy isolation stands. Similar Products Used:
