First phono stage upgrade

Hi everyone,

Looking for some perspective on upgrading my phono stage.

I got a Rega RP8 and a Vincent PHO 8 as a first step into analog a few years ago.

My Exact cartridge got damaged during a recent move so I sought out advice here on a replacement.

I traded in my Exact for the Ania Pro and arranged to sample some phono stages at a local shop.

After replacing the cartridge, they demoed my table with Musical Surrounding Nova III and a Black Ice Audio F159.
 

After several hours, the sales guy says they're closing up in a few minutes and asks if I would like to try these units at home.

I ended up taking just the Nova III with both the stock Wall Wart and optional ($650 ish) power supply.

I wanted to A/B test the power supplies first.

Then A/B test against the F159.

Are these units (or this "range") a good next step?

Am I shooting too high or low?

Still very new at this.

Thanks!
