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?

Phono preamp is for cartridge, not for turntable. If you have Moving Coil cartridge look at the cartridge output first and then look for MC phono stage designed to run a cartridge with such output. Almost any dedicated phono stage will be better than Yamaha, the rest depends on your budget. 
That is an extremely nice cartridge on what is a very nice table.  Yes, you will get much more out of it by moving to a standalone phono stage.  Frankly, you would get more out of the Ortofon 2M Bronze as well.  

Budget is relevant.  I run a cartridge that is not much more expensive and put it through a $5K phono stage.  You could see significant improvement with a $500 phono stage though and just about everything in between.  

Are you interested in tubes or SS?  Any space constraints?  Does it need to be small or do you want a full size component?

If it would make a significant improvement, I could see spending up to $1K on a separate phono pre amp. Can I run both TT out of such a pre amp? I have not thought about size, but I don't think it would be of concern, unless it was huge. I've looked at the specs of the cartridge, I see it's low output, but with limited knowledge, I'm a little over my head. Thanks for the response.

It appears to be low output, but the specs on the VDH are hand written in the box, not sure what they all mean. I'm a little over my head.
