Phono pre amp


I recently purchased a new TT a VPI Prime with a VDH DD2 special MC cartridge, I'm very happy. I still want to use my previous TT which was a Denon DP51F with a Ortofon MM2 Bronze cartridge. My VPI is plugged into the phono stage on my Yamaha AS2100. The question is, will I get more out of the VPI if I buy a (better) separate phono stage for the VPI and use the Yamaha phono stage for the Denon? If so, what phono pre amp would be good for the VPI?

This is an amazing and black phono stage for the money designed by the preeminent phono stage designer John Curl. It will only handle one turntable but that will be enough. What will most likely happen is your new turntable will be so much better that the old one will sit and languish until you finally decide to sell it. Sell it now to support the slightly higher price of this phono stage. I do not think you can do better in this price range. Parasound has a habit of giving you much more for your money.
Otherwise listen to Lewm. I can not improve on his advice.
It is hard to find, but MAGI phonomenal tube phono stage would be a good choice at $1000. It has two MM inputs. I have had a few preamps with phono cards -- Rogue Magnum 99, BAT VK 30, Plinius M16P, and Audible Illusions M3B MM. All of them had pretty good MM, but MAGI is far better than them.
If you like MC cartridges, you can add an SUT like Live! MC-10 at $1000.
So, with $2000, you can have both MM and MC cartridges.

A used Allnic H1202 sells at around 2K, and it would be a good choice.
I have both of them (MAGI, Live! MC-10, and H1202). I prefer MAGI+Live! MC-10 over H1202. Currently I am using Ortofon SPUs, Ortofon MC20 super, Denon 103R and AT150mlx cartridges. All of these cartridges work quite well with my phonos.
