I've used Rowland gear for over ten years. Old original Coherence One preamp and Model 7 monoblocs. Very very good sound and completely bulletproof. My preamp and amps have been on (the preamp doesn't even have an "on/off" switch) for over ten years and have performed beautifully and without complaint. Can't say anything first hand about the "new" generation of stuff from Rowland, but their reputation is first rate.
I don't think you can go wrong if you like the sound...
