I'm pretty sure you would like one of our preamps better, but I must say that I have not listened to a RS phono pre in maybe 20 years.
Regarding the cartridge, Eros should easily handle the ones you mention, and Reduction would work very well too if the cartridge has a reasonably high nominal output, say 5mV. The S.E.X. amp is certainly capable of letting you hear the differences between the RS preamp and ours, as well as the differences between the Reduction and the Eros, which is more or less a matter of slightly better resolution and perhaps a bit better bass control and little more natural vocal presentation from the Eros.
If there are budget constraints (something that I am very familiar with!) I think the Reduction could be a great match with your setup. The Eros will dig a little deeper, but might inspire you to try different cartridges, cables, etc.
