Jeff Rowland amps, any coments?

What happened to your Model 12s that caused you to send them back for repair? I am considering a Rowland 8Ti so any information about reliability is appreciated.

i've had a jrdg 8ti (upgraded) for >9 years. the only "repair" that's ever been needed is the replacement of bulbs in the power switch. they're built like tanks and last as long as redwoods. well, "redwoods" may be a bit of hyperbole but you get my drift.

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...

The 12s went back to factory because of failure of the switching power supplies on one and noise from the switching power supplies on the other. The 8 doesn't use switching power supplies.

Yeah, I have a comment: I wish I could afford one! I would love to get the Concentra integrated. One day possibly. JR is some of the finest audio gear in the world at any price. My recommendation: Like Nike says: Just Do It!
