Turntables

Whether it be Ortofon, Sumiko or Grado, there will still be a difference, though I don't know how big a difference.
You could talk to people at needledoctor.com
I once asked them a few questions about cartridges, and they were straightforward enough. I didn't follow the advice but because of cost not because I disagreed. They know Pro-Jects, and they will most likely mount and align the cartridge for free if you buy both from them.
Grado hum with some tables, by the way.

Thanks so much for the great advice and so sorry for the late reply. This does seem the best site to get advice. Over the past few months I have been looking hard and have now got the Clear audio concept wood MC. I have the CA nano phono stage also. I thought long and hard about what you said and decided to take a look at OK at other brands. For what I see all the components are evenly matched. Agin some of the comments I would never have thought of. As you can tell I'm new to the game. Thanks again 

The Pro-ject 6 Perspex can now come bundled with a Sumiko Bluepoint EVO III HOMC, not too surprising since Sumiko distributes Pro-Ject in the US. Still, I also concur with the previous comments because the phono stage is really where it’s at before you can completely hear what you’re paying for in cartridges.

Bundled Pro-ject 6 Perspex

I purchased the  Perspex 6 a couple months ago.  I got the package deal with the Sumiko Bluepoint evo III.  It is an amazing combo.  Just starting to get broken in and sounding better every day.  Just be careful with the cartridge if you go that route, it is very delicate and exposed.  Sounds amazing though.
