Mola Mola’s original engineer was Bruno P. Who is no longer with Mola Mola. He started Purifi a few years ago and they make the amp and speaker parts for others.
Not sure about the new guys designing at Mola Mola.
@deep_333 You should have a listen to the new SimAudio North Collection amps. These amps have a similar level of detail as the AHB2 but does not have any edge to it. I mentioned this before on this thread. I heard the 761 amp, and I agree with what the reviewers have been saying about it. The price range is $100k+ | $24k | $15k. I heard the $USD 15k one and that should be powerful enough for my Yamaha NS5000. A local dealer carries both and I may have a listen this Friday.
