I have no experience with the Mani 1. But I bought a Mani 2 for a family member as an upgrade to the built in phono pre on an Audiolab 6000A integrated. Trying it in my own system with an AudioTechnica AT 150Sa MM cartridge and the Mani 2 totally cold out of the box, there is no denying it is a great phono pre for the money. Detailed, fast, quiet, with a decent soundstage between the speakers. And the bass is remarkably deep and accurate. I would say the presentation is neutral, just presenting the facts.
The Mani 2 is hands down the best deal in new budget audio gear I have seen. Period. Wonder how good it will be once it is run in a bit. While I did not fiddle with different cartridges or settings, for use with a decent MM cart it is terrific. Highly recommended.
