Thanks Dover, I did not think about having to modify the Rega using certain cartridges. There seem to be so many well reviewed ones in audio land. It's also true that there are reviews that marry the Rega to the Allnic H7000 with great synergy. That's a very expensive direction to travel.
The Goldring carts are great to as I understand.
It's hard to know with the collection of pieces mentioned, how it will sound in the end but they are all high performers. I'm sure some tweaking would get the magic I'd be looking for.
