They work well with a wide range of amps. If you have a search way back in the thread you’ll spot a Naim NAP 120 lurking on a shelf above Jim Rogers in one of the JR brochures linked, I guess he used it whilst designing them. They sound great on anything I’ve used; Quad 303, Leak valve amps, Pass Aleph 3 etc. I bet they’d be amazing with a bit more power, e.g. a Radford STA 25. They’ll certainly show you a nice amp from an average one, but there is nothing hard about the load. I’m clearly at the bottom of the power range with the Leaks, I’d want more that 10 Watts in a larger room. I listen so close to them it is no issue and they really do sound superb.
Hello
I read somewhere that there is an attenuator for HF on the crossover that can be set to minimum, could someone explain how to do that?
My JR 149 sound is dull
My english is not very good so just to clarify - counterclockwise for more treble?
Do you know if the crossover has been recapped? Before I recapped min they sounded a bit dull/veiled but after the recap they really opened up and the dull sound went away. The treble afterwards was very clear and nothing like it was before.Hello

Is it acctualy safe to mess around with this pot with amp powered on?
A measurement mic would make it easier for us to remotely diagnose the issue, but in absence of this I'd recommend doing the following steps, one by one, and stopping when the problem is solved.Is it acctualy safe to mess around with this pot with amp powered on?
