Solid State amp to go with Audible Illusions Modulus 3a preamp

I recently acquired a newly factory refurbished Audible Illusions Modulus 3a Preamp. I was wondering if any one with the experience with this famed vintage preamp could recommend a solid state amp that would pair well.

I am currently using a Willsenton R8 in El-34 mode with a Hsu sub woofer wired using High level inputs. My speakers are vintage Linn Nexus 2 way stand mounts at about 86db efficiency. My current set up sounds excellent to my ears.

I came into this tube based preamp on a whim, and wonder if it can compete with the R8 with solid state amplification. I would like to wire the sub using high level inputs from the amp if possible.

Thanks
