I have just upgraded my project debut 3 se by adding a orfoton om-30 stylus and speedbox, although it's still a entry level deck it now sounds in a different league. I'd like to add a better phono amp replacing my pro-ject phono (£70). I will eventually buy a better deck so spending as bit more on a new phono isnt a problem as it will eventually be partnered with something like a decent Rega. I was think about buying a Rega fono mk2 or pro-ject tube box, would either be good a choice? How much of an impact does a better phono make and can it add warmth or make the sound brighter? Any advice would be welcome.
