Turntable upgrade

I too own a P6. As evidenced by the many posts, there are disparate opinions. One thing perhaps on which all can agree is that there are multiple upgrade paths, each of which can improve sound quality. My P6 has a Sumiko Songbird cartridge, similar in price and design to your Ania, elliptical not line contact, but preferred by my dealer to the Ania. 
 

I chose to upgrade my Musical Surroundings Phononena II solid state phono stage. I purchased a pre owned Modwright SWP 9.0 SE, a well regarded tube phono stage that originally retailed for about $3,000. The improvement in sound after adding this phono stage was more noticeable than the upgrade from my ProJect Debut III with Ortofon Bronze cartridge to my P6 and Songbird. Instrument timbres are more natural, imaging is better with deeper soundstage. Bass is deeper with no loss in tightness, and background noise to my ears is equally inaudible. The sound is simply more analog, more lifelike. 

Whatever you choose to do, try to audition any upgrade in your listening room with your equipment. I purchased the Modwright from a dealer with the right to return it. Once it was hooked up I never thought about sending it back. 

I had the chance to compare 3 different phono preamps if u care to upgrade there. I compared the rega aria, the rogue ares II and just the phono pre amp in my receiver. I didn’t think the rega was a huge difference from the receiver. However the rogue had more detail to it. I liked the fact it had separate power supply and tubes. I didn’t get a chance to try Hegel v10. Like sameyers1 I’m also running an ortofon bronze which was a great improvement over the red.

To be clear I agree a better phono stage will give the OP better sound with what he has, my take is go to the next level turntable and a decent mm will give a better sound than option one and from there improve down the line....better cart and better phono stage.
