Should I use an external Phono Preamp

For the OP, I have never been able to describe what I am looking for in an end sound heard with great conviction, until it is heard.

I have heard many end sounds resulting from a Phonostage Influence that I have not wedded to, but in the same system, also heard Phonostages I have felt are worthy of learning more about and how they can sound in another system, especially the home system.

Today, my main interest is in SUTs and Head Amps and how sound is produced using these as an upstream of the Phon' add-on. I have a few to try out on a list. 

Used with my newest Speakers, my very recently acquired custom design/built SS Phon' is exceptional in its early usage condition using the MC Input. Using owned SUT's into the MM Input, has caused me to reevaluate previous thoughts on the owned SUT's; a relegated model is now the go-to model for this Phon', totally unexpected that outcome.

I didn't mention I am using a Nordost Valhalla 2 tonearm cable. Maybe that could be improved?

Is this a real Valhalla 2 or a Chinese fake? 
 

While you’re answering this question, I’ll answer yours. Phono stage makes an enormous difference. Even before you upgrade your cartridge you should consider upgrading your phono stage. If you want to stay with McIntosh, their MP100 is very nice and should be a noticeable step up in performance from your in-built phono. 
There are many other phono stages, solid state and tube, that would improve your listening experience. 

What @elliottbnewcombjr said above. Configure the phono input to your cartiridge and then play around in tiny increments to improve the sound --IF necessary.

Complete and utter nonsense - the phono in the c12000 is far superior to the mid price stand alone MP100 phono.

I would have thought the more logical next upgrade of this system would be to upgrade the turntable and tonearm - Technics SP10R plus top end tonearm.

In my view to upgrade the phono input of the McIntosh you would be looking at 10k phono to get some improvement, but as I said, upgrading the turntable and arm will give more fundamental improvements.

For a different sound, perhaps look at some alternative cartridges.
