I think you should take a look Klyne;Stan Klyne makes some of the best solid state pre amps in high end audio;either a series 6 or 7 is what I would be looking for;if you don't need balanced inputs and outputs then the series 6 would do the job.
Check his website if you need more info or even call Stan as he is a great guy to talk audio with.
