I have not, but I have been listening to passives and they are great with the right amp. I think the Atma-spheres are not ideal for an external passive, but I suspect that with Ralph building it into the unit customized for the specific load and sensitivity of the amp and no ICs that it is great, of course you loose a bit of flexibility compared to an standalone preamp. Would love to A/B a MP1 versus the integrated passive volume control.
