"What amplifier will the preamp drive? What is the amplifier gain and input impedance? Do you need XLR connections? 
There’s no one answer. You have to match the preamp to your amp."

The amp, while very high quality is a very little know cult model. And I do clearly understand preamp/power amp matching. XLR connections are not needed, The amplifier spec of importance is:

amplifier input impedance 180k ohms

I appreciate the Audio Research LS suggestions, but it's always been my understanding that, being true balanced designs, you need a power amplifier thats also XLR to truly reach the best performance level. My amplifier is purely single ended. 

Do you want the phono stage or is a line stage what you're looking for?

All of the Audio Research LS models recommended have rca and xlr inputs and outputs. You are not restricted to balanced only.

@nightfall the ARC LS-25 is an outstanding preamp and offers gain adjustment and will work well with 180kohm input imp amplifier. Might be worth looking into it if you can spot one used. But sounds as if the XLRs aren’t a requirement. You then have CJ and even Rogue RP5 in that price range.
