Advice on Phono Cartridge

Go with the Ortofon 2M Blue as it's compliance is a much better match for the Pro-ject tonearm that is pretty low mass.  The Denon is way too low in compliance and would result in a unwanted resonance of around 17 Hz. 

Also the Denon is a low output MC and without knowing what phono stage you have, you have to make sure you have a very good one.  Entry level MC phono stages just don't cut it and are often way too noisy (audible hiss) when you need 60db of gain for a LOMC.

Thanks Paraneer!  My phonostage is the phono module in a NAD 375BEE.  I also have a Pro-Ject phono stage (the cheap one), but I think I prefer the NAD module.

What does that mean, that the compliance is a better match for the tonearm?  How do you determine if a cartridge will mate well with a tonearm?  Do high end tonearms work well with all cartridges, or is that not necessarily true?

Thanks! 

The compliance rating of a cartridge refers to its suspension or "springiness" while playing a record with mass bearing down on it.  In this case, the mass is the tonearm.  Years ago most cartridges were high compliance as low mass tonearms (like yours) were the rage.  Today, MC cartridges are in favor and these tend to be low compliance and work better with medium to high mass arms.  At an effective mass of 9.5 grams, your tonearm would be low mass.  The Ortofon has a compliance rating of 20 while the Denon is only 5. 

And the Denon is very low output MC and I would doubt that the built-in phono stage on your NAD would be quiet enough to reduce any hiss.  Assuming that it has a MC setting.

I would stick with higher compliance MM cartridges for your Pro-ject TT. The Ortofon 2M Blue is a good choice for it.

You need to know the effective mass of the arm, the compliance rating of the cartridge and the cartridge weight (add a 1/2 gram for mounting hardware) to determine if its a good match.  Here is a handy link to a tool that will help determine the cartridge/tonearm resonance with regards to its compliance rating...

You can also google cartridge compliance to learn more about this.

So it is not necessarily true that high end tonearms work well with all cartridges. 

Thanks Paraneer!  That is a handy tool, I'm curious as to the math behind the chart.

As with most things, every answer seems to generate 2 more questions.  I will definitely do some more research on this.

Do you have any actual personal (listening) experience with the 2M Blue?  If so, do you think it's worth the hype?

Thanks for the suggestion wolf_garcia.  I hadn't really looked into the Pearl.  It does appear to be a good fit for my tonearm also.  The price is good,  but I would probably tend to lean towards the 2M Blue, just because of all the good reviews.  It's too bad you can't go to "the store" and compare all these cartridges side by side.

My inlaws had an old Marantz turntable (6100 I think) and that sounded better than my Debut III.
