Phone pre advice - Would I benefit from this upgrade?

Try a Puffin, you’ll never go back.

If you want LP wow maybe an AT 540ML,  740ML or 750SH first.

You could put the 2m Bronze on that turntable, I think it’s the same weight. I think even the Musical Fidelity lx2 lps phono would be better than what the Yanaha offers. It can still be had for about $379. So, an $800 investment. On second thought, the fact you mention a new table @ 2k makes me think the music hall mmf-7.3 with the 2m Bronze already installed. For that table, I’d move up from the aforementioned musical fidelity to the pro-ject tube box DS2, which I think is still available @ about $899. The 2m Bronze matches well with tube preamps.

@jwaller50 I've had great sonic success with the DL-160 it's older sibling. I am told they are very similar. 

If the Orbit is not the special, the platter upgrade should probably be considered for purchase. The platter upgrade makes quite an audible difference. Also consider their record weight or anyone else’s weight for that matter. Once those items are added, the Orbit is quite a nice unit. Also the newer units have an improved tonearm. 

Phono pre's are my favorite upgrade. I can honestly recommend all that I've had. Musical Surroundings Nova III and Manley Chinook. Both fantastic and fun upgrades. I can also recommend the Clearaudio Concept Wood coming from a Rega P2. Whatever path you take, you're in a fun place.
