I had the mmf 2.2 for 4 years. Everything broke on it, after the warranty expired. I had to learn how to fix things, luckily it’s simple enough.
It sounded good though.
Rega 1 or 2 are not upgrades to the mid-level Music Hall. Rega 3 is. Pro-Ject and Music Hall share some parts, so there is why I didn’t go with Pro-Ject.
You got a lot of choices, Fluance with the Ortofon blue, for example.
I would avoid built in Phono and auto anything. Keep it simple. A simple but quality Phono stage in the future, new cartridge, etc. Also consider the resale options: who buys Rega vs Music Hall in the used market? If you want to upgrade.... the whole rig.
