Greg makes a valid point, but if the Denon DL103 is a little low on the output side, consider the Denon DL110 - another top performer. Should be a great match for the Mani, but you will need to add a spacer to increase the mass to be compatible with the Rega arms.

http://www.needledoctor.com/Denon-DL-110-Cartridge?sc=2&category=369In the past I’ve tried a couple of Nagoka’s, but despite their Very clean, extremely detailed and well behaved performance, they were not quite as warm and as well balanced as the Denon’s.. Perhaps compliance was the issue?
The Goldring was an OK performer, but lacked the dynamics of the Denon 103.
The Rega Elys was just an all round disappointment - lacked details, clarity and dynamics. Perhaps the phono stage was the problem? Maybe, but the other carts fared much better. It should have been excellent, not mediocre.
The Grado I had was returned because the hum increased as the cartridge got closer to the motor on the Rega. It was a very nice cart, but has poor shielding - if any - such a shame.
I must admit I have a bias towards Denon, but that’s because they are so easy to setup and they are very forgiving when it comes to less than perfect setup. They are also top performers if you get setup spot on. And they can be tweaked to a level of excellence reserved for carts costing much much more
As far as turntables - I own(ed) a Rega and have spent 30 years tweaking and upgrading to get it to where I am happy - if I had my time over I’d look at a VPI. But there are some stellar performers from Music hall and Project.
Here are my tweaks -
http://image99.net/blog/files/category-turntable-mod0027s.htmlTry to get a turntable that has the drive belt that goes around the edge of the platter - it puts far less stress on the drive belt and gets the platter up to speed much quicker. Having the drive belt driving a subplatter, like the Rega, requires the operator to perform the "Rega Nudge" to reduce startup time.
Also - the glass platter on the Rega looks cool and keeps wow/flutter to a minimum - and that’s all it’s good for. you will spend time and money trying to get the perfect mat, or end up replacing it with an acrylic platter for best results
Hope that helps
